DETAILED DESCRIPTION

[0091] It is clear from FIG. 1 that individual elements of a measuring instrument assembly 1 are connected via data and/or energy lines. The measuring instrument assembly 1 comprises a measuring instrument apparatus 2 for measuring electrical measurement variables, wherein the measuring instrument apparatus 2 comprises a measuring unit 4 comprising measuring electronics 3, and an output unit 5 comprising at least one output means 6. It can be possible for an item of information generated from the measuring unit 4 and/or relating to the measuring unit 4 to be output via the output unit 5. In this case, the output unit 5 can be or is detachably, i.e. non-destructively detachably, connected to the measuring unit 4, cf. FIG. 2.

[0092] The measuring unit 4 and/or the output unit 5 comprises or comprise an electrical energy store 7, 8. At least one energy store 7, 8 can for example be arranged or able to be arranged detachably, i.e. non-destructively detachably, in or on the measuring unit 4 and/or the output unit 5. For example, an electrical energy store 7 is inserted or fixed in a receiving portion of a main body 9 of the measuring unit 4. The main body 9 of the measuring unit 4 can for example receive the measuring electronics 3. At least one securing means 10 can be arranged in or on the main body 9 so as to be detachable, preferably without dismantling a housing or housing component that forms the main body 9. A charging cable 12 provided with a plug 11 can be connectable to the main body 9 of the measuring unit 4 and/or to the output unit 5, by means of said plug 11 the measuring unit 4 and/or the output unit 5 can be connected to an external energy supply network (e.g. household plug socket), and used for the operation of the measuring unit 4 and/or the output unit 5 and/or for the charging of an electrical energy store 7, 8 arranged on the measuring unit side and/or on the output unit side. The plug 11 and/or the charging cable 12 can in particular be designed purely as a power pack, such that it does not form a charging device, and influencing of the charging event (control and/or monitoring of the charging process), which may be required for charging the electrical energy store 7, 8, is arranged or can be implemented on the measuring unit side and/or the output unit side and/or the energy store side.

[0093] The main body 9 of the measuring unit 4 comprises at least one interface, in particular a testing instrument connection socket 13, for supplying a test current into the measuring unit 4 or to the measuring electronics 3. At least one testing instrument 14, in particular a test probe, can be connected indirectly or directly to the at least one testing instrument connection socket 13. In this case, the testing instrument 14 is preferably connected to the measuring unit 4 via a connecting body, in particular via a connection cable 15.

[0094] The output unit 5 can comprise at least one input means 16, wherein a control signal acting on the measuring unit 4, and/or an item of information that can be associated with a measured value that is determined and/or is to be determined via the measuring unit 4, and/or an item of information that modifies a measured value determined via the measuring unit 4, can be input via the input means 16. The input means 16 can be designed for example as a button and/or as a touch screen and/or as rotating means 17, cf. FIG. 4. An input means 16 designed as rotating means 17 can for example comprise an axis of rotation which extends in parallel with an outside edge of a housing forming the output unit 5. The rotating means 17 is preferably arranged off-center, in or on the housing. In the embodiment shown in FIG. 4, the rotating means 17 is designed as a cylindrical body, wherein at least the lateral surface of the rotating means 17 is exposed, at least in portions, in particular completely, over the axial and/or radial extent of the rotating means 17. It can optionally be provided for the rotating means 17 to overhang or protrude, at least in regions, beyond at least one surface 18, 19 of the housing of the output unit 5 that forms the output unit 5. The rotating means 17 is preferably raised, at least in portions, relative to a main extension surface 18 and/or over a lateral surface 19 of the, preferably cuboid, housing of the output unit 5. Comfortable operation of the rotating means 17 can be achieved by the region of the rotating means 17 that protrudes, at least in portions, with respect to at least one surface 18, 19 of the output unit 5. Thus, for example, the rotating means 17 can be touched or operated by the thumb of the left hand, and in the process the output unit 5 itself can be held with the right hand and/or with the left hand. It can thus be possible for the rotating means 17 to be arranged close to a lateral edge or to a lateral surface 19 of an, in particular cuboid, output unit 5, in such a way that, despite holding laterally or on the lateral surface 19, by means of a hand, the rotating means 17 can be operated using a finger, in particular using the thumb and/or the forefinger and/or the middle finger, of the holding hand.

[0095] The output means 6 shown in the figures can be designed for example as a screen, in particular as a touch-sensitive screen (e.g. touch screen).

[0096] FIGS. 6, 7, 8, 9, 14, 15, 16 and 17 show carrier units 20, some of which are designed differently, via which a measuring unit 4 and/or an output unit 5 can be indirectly or directly carried by a person. In the following, the term “carrying device” 21 means a carrier unit 20 for carrying at least the measuring unit 4, and the term “carrying means” 28 means a carrier unit 20 for carrying at least the output unit 5. Of course, a carrier unit 20 and thus a carrying device 21 and/or a carrying means 28 can be designed or configured for carrying the measuring unit 4 and, simultaneously or alternately, the output unit 5. Consequently, a measuring unit 4 can be or is connected in or on a carrying device 21 which can be carried by a person. In particular the carrying device 21 is designed or configured such that the measuring unit 4 can be carried in the region of the back of a person, via the carrying device 21, cf. FIG. 15.

[0097] The carrier unit 20, in particular the carrying device 21 and/or the carrying means 28, can be designed for example as part of an outer garment. Thus, the measuring unit 4 and/or the output unit 5 and/or a functional unit 46 can be detachably fastened to a piece of clothing which is designed for example in the manner of a jacket, a coat or a waistcoat. In particular, this detachable fastening is achieved using connecting means 47, 47′.

[0098] The carrying device 21 can for example comprise a receiving region 23 which is defined at least in portions, in particular completely, by a wall portion 22 and is intended for indirectly or directly receiving the measuring unit 4.

[0099] In the embodiment shown in the figures, the measuring unit 4 is arranged in a receiving body 50 and is fastened to the carrying device 21, together with the receiving body 50. The receiving body 50 can be designed for example in the manner of a case or container, cf. FIG. 11.

[0100] The receiving body can be provided on at least one surface with at least one connecting means 47 which can be connected to a connecting means 47′ arranged on the carrying device side. In the embodiment shown in FIGS. 17 and 18, the receiving body 50 comprises at least two, in particular three, connecting means 47 which, in the assembled stated of the receiving body 50 and carrying device 21, correspond or connect to connecting means 47′ arranged on the carrying device side. In this case, a locking means or a closure element 31 can be arranged at least one connecting means 47, 47′ and/or in the region of at least one connecting means 47, 47′, which locking means or closure element secures the assembled state and prevents unintentional detachment of the receiving body 50 from the carrying device 21. For example, said connection can be released or detached only by intentional action, e.g. an actuation of an actuation means 49.

[0101] For example, the receiving body 50 comprises two receiving chambers 51, 52, wherein the receiving chambers 51, 52 can be separated or can be at least temporarily separable by means of a partition wall 53. According to the embodiment shown in FIG. 13, the partition wall 53 can be provided with at least one aperture 54. The aperture 54 makes it possible to guide a cable, connected in a first receiving chamber 51, into a second receiving chamber 52. Thus, the measuring unit 4 can be placed in a first receiving chamber 51 for example. Thereafter, said receiving chamber 51 can be spatially separated from the second receiving chamber 52 by closing the partition wall 53. The aperture 54 of the partition wall 53 can be dimensioned and/or formed such that a measuring unit 4 received in the first receiving chamber 51 cannot be guided through, such that the measuring unit 4 can be “trapped” in the first receiving chamber after closing the partition wall 53.

[0102] The aperture 54 can make it possible to guide a connection cable 15, connected to a measuring unit 4 received in the first receiving chamber 51, and/or a charging cable 12, through the aperture 54, such that said cable reaches into the second receiving chamber 52 or can extend, at least in portions, as far as into the second receiving chamber 52. A connection and/or charging cable 15, 12 located in the second receiving chamber 52 can now be guided towards the outside of the receiving body 50, via an opening region 55 that connects the second receiving chamber 52 to an outside of the receiving body 50. This makes it possible to guide a cable out to the outside region of the receiving body 50, from the first and/or second receiving chamber 51, 52, via just one interface. The just one interface reduces the risk of contamination or penetration of dirt into the first and/or second receiving chamber 51, 52.

[0103] The opening region 55 for guiding out at least one cable, in particular a connection and/or charging cable 15, 12, can for example comprise a resilient element which keeps the effective opening cross section as small as possible. For example, in the case in which no cable is guided through the opening region 55, the resilient element can close the opening cross section as far as possible. For example, the resilient element is a preferably foamed, resilient plastics material, or is designed in a brush-like manner.

[0104] The opening region 55 can be formed for example in the region, in particular on an end region, of a slide fastener which temporarily closes the opening of the first receiving chamber 51.

[0105] For example, the output unit 5 can be received in the second receiving chamber 52. In particular, the aperture 54 is dimensioned and/or formed or designed such that, in the state in which the second receiving chamber 52 is closed by the partition wall 53, it is not possible to guide the output unit 5 through from the second receiving chamber 52 to the first receiving chamber 51. In other words, the aperture 54 can be dimensioned and/or formed or designed such that, in the state in which the second receiving chamber 52 is closed by the partition wall 53, the output unit 5 received in the second receiving chamber 52 is trapped.

[0106] In the embodiment shown in FIG. 14, the cover wall portion 56, which closes the second receiving chamber 52 to the outside, is shown broken open in part, see arrow 57, which shows the region that is broken open. The region broken open makes it possible to see the aperture 54 of the partition wall 53 and the plug socket portion of the measuring unit 4 located therebelow and arranged in the first receiving chamber 51. In this case, the plug socket portion can for example comprise at least one testing instrument connection socket 13 and/or a charging cable connection socket. It can prove to be advantageous if, as shown in FIG. 14, the plug socket portion, in particular at least one testing instrument connection socket 13 and/or at least one charging cable connection socket, is arranged or formed relative to an aperture 54 of the partition wall 53 such that insertion and/or unplugging of a plug, to be inserted into or removed from the plug socket portion, can be carried out during a state in which the first receiving chamber 51 is closed by the partition wall 53. In other words, when the second receiving chamber 52 is open, by means of guiding a plug through the aperture 54, said plug can be connected to or disconnected from the measuring unit 4, while the measuring unit 4 is placed in the first state, closed by the partition wall 53, of the first receiving chamber 51.

[0107] FIG. 11 shows a receiving body 50, the second receiving chamber 52 of which is open, and the first receiving chamber 51 of which is closed. At least one bag or a fastening means can be arranged or formed in the second receiving chamber 52, which allow for fastening and/or secure receiving of the output unit 5 in the second receiving chamber 52. A similar bag and/or fastening can be arranged or formed in the first receiving chamber 51, for fastening and/or receiving the output unit 5. For example, a fastening of this kind can be formed by a belt (not shown), which can be secured and fixed, at least in portions, via an output unit 5 and/or measuring unit 4. For example at least one, in particular three, connecting means 47 can be arranged in the first receiving chamber 51 such that fastening of a measuring device 4 received in said first receiving chamber 51, in particular of a receiving body 50 received in the first receiving chamber 51, can be achieved via said connecting means 47 on the receiving chamber side. For this purpose, in the state in which the receiving body 50 is inserted into the receiving chamber 51, the connecting means 47 on the receiving body side can be brought into engagement with the connecting means 47 on the receiving chamber side, cf. FIGS. 13 and 18.

[0108] In FIG. 12, the receiving body 50 is shown partially transparent, wherein the measuring unit 4 is arranged or formed in the first receiving chamber 51, and the output unit 5 is arranged or formed in the second receiving chamber 52, which is separated from the first receiving chamber 51 by the partition wall 53. It can be provided for example for a cable, in particular a charging and/or connection cable 12, 15, to be guided or to be able to be guided from the measuring unit 4 arranged in the first receiving chamber 51, directly to the outside of the receiving body 50, cf. arrow 58 in FIG. 12

[0109] The wall portion 22 of the carrying device 21 can for example surround the receiving region 23 in a U-shaped manner, such that the measuring unit 4 or the receiving body 50 can be introduced into the receiving region 23 via the free or open region of the U-shaped wall portion 22, cf. FIG. 15. The wall portions 22 can be of a constant height or of different heights; in the embodiment shown, the wall portion 22 is of different heights at different sites, cf. FIG. 15.

[0110] The wall portion 22 of the carrying device 21 can for example comprise an opening 48 which is designed and/or formed such that, in the state in which the carrying device 21 and the measuring unit 4 are assembled, in particular a measuring unit 4 received in a receiving body 50, a connection cable 15 guided from the measuring unit 4 to a testing instrument 14 can be guided through the opening 48 or is located there. The opening 48 can for example, as shown in FIG. 14, be designed as a region that is open on one side, or as a U-shaped opening 48 of the wall portion 22. As a result, insertion and separation or removal of a measuring unit 4, in particular positioned in a receiving body 50, into or from the receiving region 23 of the carrying device 21 can be made possible, wherein the connection cable 15 always remains connected to the measuring unit 4 and the testing instrument 14. In this case, the opening 48 can be arranged or formed such that it coincides with the opening region 55 and/or with the insertion and/or retraction movement of the measuring unit 4 or of the receiving body 50 receiving the measuring unit 4, such that a cable, in particular a charging and/or connection cable 12, 15, can remain connected to the measuring unit 4, during the insertion and/or retraction movement.

[0111] The carrying device 21 can be placed or carried on at least one shoulder of a person carrying the carrying device 21, via a carrying system 24 which comprises at least one shoulder element 25. In particular, the at least one shoulder element 25 is designed as a shoulder strap. In addition and/or as an alternative to a shoulder element 25, the carrying system 24 of the carrying device 21 can comprise at least one hip element 26, wherein a connection between the carrying system 24 and a hip region 27 of a person carrying the carrying device 21 can be established via the hip element 26.

[0112] The shoulder element 25 and/or the hip element 26 can be designed in a strap-like manner and can thus have a minimum rigidity which makes it possible to establish a carrying function between the body part of the person and the carrying system 24, without entirely surrounding a body extremity or limb of the person by the shoulder element 25 and/or the hip element 26. In this case, the strap-like shoulder and/or hip element 25, 26 can have a non-limp property. The shoulder and/or hip element 25, 26 can comprise a cushion portion (not shown), at least in portions, in particular in the region of the contact surfaces for contact with a person carrying the carrying system 24, wherein the cushion portion can be connected to a carrier body (not shown) having the non-limp property, which ensures the actual carrying function.

[0113] For example, the output unit 5 can be connected in or on the carrying means 28, and can thus be able to be carried, by means of a carrying means 28 that can be carried by a person, cf. FIGS. 6 to 9. For example, the carrying means 28 is designed or configured such that the output unit 5 can be carried or is portable, via the carrying means 28, on a hand region and/or an arm region 29 of a person. In this case, the carrying means 28 can for example comprise a base body 30 on which, in particular via a connecting means 47, the output unit 5 can be detachably fastened. The base body 30 can be fastened to a hand and/or arm region 29 for example by means of at least one strap portion 32, in particular provided with a hook and loop fastener (barbed hook principle, which interact with loops).

[0114] The carrying means 28 shown in FIGS. 6 to 9 comprises a finger portion 33 which reaches into a hand and/or finger region of the person carrying the carrying means 28, and an arm portion 34 arranged in the arm region 29 of the person. By means of the connection or by means of an extension of the finger portion 33 of the carrying means 28 extending for example between the thumb and at least one further finger of the hand, twist prevention of the carrying means 28 relative to the arm carrying the carrying means 28 can be achieved. In other words, the base body 30 of the carrying means 28 can comprise a geometrically shaped or formed region, which, when the carrying means 28 is used as intended, performs a twist prevention function and/or prevents twisting of the carrying means 28 relative to the arm.

[0115] In particular if a twist prevention means is provided between the carrying means 28 and the arm, it can prove to be advantageous for the base body 30 to be designed such that, in the state in which the carrying means 28 and the output unit 5 are connected, in the case of an arm extended forwards, the output unit 5 is inclined inwardly, about the longitudinal axis of the arm, i.e. towards the head or center of the person carrying the carrying means 5. This makes it possible for, on the one hand, the output unit 5 to always have a defined orientation relative to the arm (twist prevention), and in addition, by means of the design of the base body 30 that allows for an inclined arrangement, for an output means 6 of the output unit 5 to be easy and comfortable for a person carrying the carrying means 5 to observe and/or operate, cf. FIGS. 8 and 9.

[0116] Different embodiments of an adapter means 35 are shown in FIGS. 2 to 4, wherein the adapter means 35 can be or are connected (a) to the output unit 5 and the measuring unit 4 or between said units, and/or (b) to the output unit 5 and a carrying means 28 or therebetween. In this case, the adapter means 35 is designed for example such that a relative position and/or orientation of (a) the output unit 5 and measuring unit 4, or (b) of the output unit 5 and carrying means 28, or (c) of the measuring unit 4 and installation surface 42, relative to one another, can be changed using the adapter means 35. For this purpose, the adapter means 35 can comprise at least two adapter elements 36, 36′ which are mounted so as to be rotationally and/or translationally movable relative to one another, wherein a measuring unit 4 and/or a carrying means 28 can be or is connected to a first adapter element 36, and an output unit 5 can be or is connected to a further adapter element 36′. A swivel axis 37 of an adapter means 35 can preferably be designed or arranged such that, in the assembled state of the adapter means 35 and the output unit 5, and/or of the adapter means 35 and the measuring unit 4, the swivel axis 37 of the adapter means 35 is oriented in parallel with an outside edge of the measuring unit 4 and/or of the output unit 5.

[0117] In a preferred embodiment, at least one relative position and/or orientation (a) of the output unit 5 and measuring unit 4, and/or (b) of the output unit 5 and carrying means 28, relative to one another, can be locked, in particular using the adapter means 35. For this purpose, for example an at least temporary release of the locking can be carried out by actuating a mechanism (not shown), in order to achieve a locked state again after the actuation has ended.

[0118] A change in the relative position and/or orientation (a) of the output unit 5 and measuring unit 4, and/or (b) of the output unit 5 and carrying means 28, in particular via the adapter means 35, can for example be designed so as to latch in at least one predefined relative position and/or orientation. In other words, at least one latching means (not shown) can be provided, which specifies a latching movement of the measuring unit 4 and output unit 5, or of the output unit 5 and carrying means 28.

[0119] The output unit 5 and/or the measuring unit 4 can comprise for example at least one detachable electrical energy store 7, 8 for supplying energy to the output unit 5 and/or the measuring unit 4. In the state when detached from the output unit 5 and/or from the measuring unit 4, said electrical energy store 7, 8 can be connectable or fastenable to a carrying device 21 and/or to a carrying means 28 and/or to a belt holding means 38, via a connection interface, e.g. by means of a connecting means 47, 47′.

[0120] For example an electrical accumulator (not shown) can be arranged or formed in or on the carrying device 21 and/or in or on the carrying means 28, wherein, in the state when connected to the carrying device 21 and/or in the state when connected to the carrying means 28 (a) the measuring unit 4 and/or (b) the output unit 5 and/or (c) an electrical energy store 7, 8 detached from the measuring unit 4 and/or from the output unit 5, an electrical energy store 7 of the measuring unit 4 and/or an electrical energy store 8 of the output unit 5 and/or the electrical energy store 7, 8 detached from the measuring unit 4 and/or from the output unit 5 can be chargeable.

[0121] The measuring instrument assembly 1 can for example comprise a stand unit 41, wherein an output unit 5 and/or a measuring unit 4 can be or is connected to the stand unit 41, wherein the stand unit 41 is designed such that purposeful orientation and/or positioning of the output unit 5 and/or measuring unit 4 connected to the stand unit 41, relative to an installation surface 42 of the stand unit 41, can be carried out. For example, the stand unit 41 can comprise at least one, in particular at least two, installation feet 43, 43′, which feet are of variable shape and/or length, in particular bendable, cf. FIG. 10. The stand unit 41 can also be used for supporting the measuring unit 4 relative to an installation surface 42, cf. FIG. 4. In this case, the stand unit 41 can comprise a placement bracket 44, the position and/or orientation of which, relative to a stand base body 45, can be changed, in particular the stand base body 45 can be shifted, in particular locked and/or plugged, into predefined positions and/or orientations relative to the placement bracket 44. The stand main body 45 can for example be connected to the measuring unit 4 via a connection interface, in particular via a connecting means 35.

[0122] At least parts of the measuring instrument assembly 1 can be connectable to one another via force-fitting and/or form-fitting connecting means 47. In particular (a) the output unit 5 and the measuring unit 4, and/or (b) the output unit 5 and a functional unit 46, and/or the measuring unit 4 and a functional unit 46, are or can be interconnected in a force-fitting and/or form-fitting manner, via corresponding connecting means 47. The functional unit 46 preferably comprises an electrical energy store 7, 8 and/or a carrying device 21 and/or a carrying means 28 and/or an adapter means 35 and/or a belt holding means 38 and/or a testing instrument 14 and/or a stand unit 41. A connecting means 47 comprising at least one force-fitting connection can comprise at least one frictional connection portion and/or at least one field connection portion (magnetic field forces).

[0123] The measuring instrument assembly 1 can comprise a testing instrument 14 which comprises a test tip 39 and a testing instrument main body 40, wherein selectively different test tips 39 can be connected to at least one testing instrument main body 40, cf. FIGS. 19 and 20. At least one, in particular all, test tips 39 and/or testing instrument main bodies 40 can be able to be fastened via connecting means 47 to a belt holding means 38 and/or to other functional units 46 via corresponding connecting means 47.

[0124] The output unit 5, the measuring unit 4 and at least one functional unit 46 can for example comprise a connecting means 47 of the same type, which can be or is connected to corresponding connecting means 47 of a further functional unit 46, in particular a functional unit 46 designed as an electrical energy store 7, 8 and/or carrying device 21 and/or carrying means 28 and/or adapter means 35 and/or belt holding means 38 and/or testing instrument 14 and/or stand unit 41 and/or receiving body 50.

[0125] For example a first connecting means 47 can be arranged or formed on the output unit 5, and a further connecting means 47′, which is different from the first connecting means 47 and can be connected to the first connecting means 47, can be arranged or formed on the measuring unit 4 and/or on an adapter means 35, wherein at least one first functional unit 46 comprises a first connecting means 47, and at least one further functional unit 46, which is different from the first functional unit 46, comprises a further connecting means 47′. Thus, as a result of for example non-compatibility of the first connecting means 47 with one another, and the non-compatibility of the second connecting means 47′ with one another, but the compatibility of a first connecting means 47 with a second connecting means 47′, a purposeful combinability of the measuring unit 4, the output unit 5, and defined functional units 46, can be specified, in particular by the manufacturer. This can simplify the handling, in particular an autodidactic use or connection of the individual elements of the measuring instrument assembly 1 described herein. Two interconnectable connecting means 47, 47′ can for example form a twist-proof connection in the connected state.

[0126] The adapter means 35 can for example comprise first connecting means 47 and second connecting means 47′ which can be connected to the first connecting means 47, such that all the functional units 46 can be connected to the adapter means 35.

[0127] The connecting means 47, 47′ can be designed as a connecting means 47, 47′ that is consistent or of the same type over a plurality of units of the measuring instrument assembly; in the embodiment shown, the connecting means 47, 47′ is designed as closure means of the SNAP series by the company Fidlock GmbH (Germany).

[0128] The measuring instrument assembly 1 described herein comprises a measuring instrument apparatus 2, wherein the measuring instrument apparatus 2 comprises a measuring unit 4 and an output unit 5 which can be detachably connected to the measuring unit 4. In addition to the measuring unit 4 and an output unit 5, the measuring instrument assembly 1 can comprise at least one functional unit 46. In this case, the functional unit 46 can for example comprise a carrier unit 21 and/or a carrying means 28 and/or an electrical energy store 7, 8 and/or a testing instrument 14 and/or an adapter means 35 and/or a belt holding means 38 and/or receiving body 50.

[0129] FIGS. 21 and 22 show a carrying means 28 carried on the torso of a person. An output unit 5 is fastened to said carrying means 28 via an adapter means 35. According to FIG. 21, the output unit 5 is arranged or formed at a first distance 61 from the head of the person, and according to FIG. 22 at a second distance 62 from the head of the person, which is larger compared with the first distance 61. This is achieved, by way of example, in the present case, in that an L-shaped adapter means 35 is rotated, at least temporarily, or permanently, about the axis 60 (for example an axis 60 extending in parallel with the viewing direction of the person carrying the carrying device) (in this case, by way of example: rotated about 180°). It can also be provided for the output unit 5, the carrying means 28 and/or the adapter means 35 to comprise translationally and/or rotationally movable elements, which allows for a straight and/or rotating relative movement between the carrying means 28 and the output unit 5, in order to change the distance 61, 62 and/or the orientation (angular position) of the carrying means 28 relative to the head of the person.

[0130] In the overview of FIGS. 21 and 22 it can be seen that the adapter means 35 can be fastened to the carrying means 28 in at least two different orientations. Alternatively or in addition, it can be provided for the output unit 5 to be able to be fastened to the adapter means 35 in at least two orientations.

[0131] According to FIG. 23, a support means 63 can be provided, which, in a state in which the carrying means 28 and/or the carrying device 21 (e.g. rucksack) is deposited on the ground, allows said carrying means 28 or the carrying device 21 sure footing. It is possible to detachably connect the support means 63 to the carrying means 28 and/or to the carrying device 21. The support means 63 is preferably detachably connected to corresponding connection interfaces of the carrying means 28 and/or of the carrying device 21 via mechanical connecting means 47, 47′. The connecting means 47, 47′ of the support means 63 are particularly preferably designed in the same way as the connecting means 47, 47′ for mechanical connection to the measuring unit 4 and the output unit 5.

[0132] The support means 63 can for example be of a frame-like shape, in particular in the shape of a closed frame or a closed ring. The support means 63 can preferably be substantially in the shape of a ring-like body, which extends, at least in portions, out of a main extension plane.

[0133] It is thus possible for the support means 63 to comprise two side elements 64, 64′ and two connecting elements 65, 65′, wherein the side and connecting elements 64, 64′, 65, 65′ form a closed ring. The side elements 64, 64′ can be for example L-shaped, wherein a first connecting element 65 is arranged or formed on a first limb of the L-shape of the at least one side element 64, 64′, and a further connecting element 65′ is arranged or formed on the second limb of the L-shape of the at least one side element 64, 64′. In particular, the side elements 64, 64′ can be oriented in parallel with one another and/or the connecting element 65, 65′ can be oriented in parallel with one another.

[0134] For example, a functional unit 46 can be fastened to the support means 63, preferably via corresponding connecting means 47, 47′. In the embodiment shown in FIG. 23, a functional unit 46 designed as a conductor means holder 66 is detachably fastened to the support means 63. In other words, the conductor means holder 66 can carry a conductor means (e.g. cable) and thus form a cable drum. For this purpose, the support means 63 can comprise a fastening region on a side and/or connecting element 64, 64′, 65, 65′, on which fastening region corresponding connecting means 47, 47′ are arranged or formed, in order to establish a detachable fastening to a functional unit 46. In addition to the lateral arrangement, which is shown, of the functional unit 46, in particular the conductor means holder 66, this can also optionally take place centrally below the measuring unit 4 carried via the carrying means 21.

[0135] It may for example prove advantageous for the support means 63 to carry or be designed as a functional unit 46, in particular a conductor means holder 66, in such a way that, in a state when placed on the ground, in a manner as intended, the functional unit 46, in particular the conductor means holder 66, does not touch the ground. In the case of a functional unit 46 designed as a cable drum, this makes it possible to allow for unwinding of the cable from the cable drum, without there being a resistance on account of possible contact of the cable drum with the ground.

[0136] According to FIG. 23, at least one belt holding means 38 for modular, in particular selective, fastening of at least one functional unit 46 and/or a measuring unit 4 and/or an output unit 5 can be arranged on at least one belt of the carrier unit 20, in particular of the carrying device 21.

[0137] By way of the connecting means 47, 47′, the present measuring instrument assembly 1 has a modular structure with regard to the connectability of the measuring unit to the output unit and optionally to further functional units 46. For example, the table shown in FIG. 24 gives an overview of the connection options, by way of example, which result on account of corresponding connecting means 47, 47′ which are provided or formed or arranged on the respective units 4, 5, 46.

[0138] The tables shown in FIGS. 24 and 25 show the combinability with regard to the connectability of the individual units 4, 5, 46. In this respect, the rows and columns are determined as follows: ME corresponds to the measuring unit 4; AE corresponds to the output unit 5; FE1 corresponds to the adapter means 35; FE2 corresponds to the testing instrument 14; FE3 corresponds to the handle; FE4 corresponds to the carrying device 21, in particular carrying system 24; FE5 corresponds to a carrying unit 20 designed as a receiving body 50, in particular as a bag or rucksack; FE6 corresponds to a carrying device 21 designed as a waistcoat; FE7 corresponds to a carrying device 21 carried on the torso of a person; FE7 corresponds to a support means 63; FE8 corresponds to a conductor retaining means 66.

[0139] In an alternative embodiment, by way of example, the measuring unit 4, the output unit 5 and/or at least some of the functional units 46 can be designed having connecting means 47, 47′ of the same type, such that there is a defined combinability or connectability among the units 4, 5, 46. For this purpose, the connecting means 47, 47′ can be designed in the manner of a plug/socket connection, which fits together only a connection of two different connecting means 47, 47′ (female/male connector type). It can thus be made possible to purposely prevent certain connection combinations of the units 5, 6, 46, by means of the provision of the respective types of connecting means 47, 47′.

[0140] In this case, the table shown in FIG. 25 is to be understood such that the associations of units 4, 5, 46 denoted by “X” cannot be directly interconnected, on account of the connecting means 47, 47′ provided on the respective units 4, 5, 46. In this case, a first embodiment can exhibit exclusively a connectability or non-connectability of one row of the table, and thus of one unit 4, 5, 46 with respect to the remaining units 4, 5, 46. In a second embodiment, the combinability according to at least, in particular exclusively, one row of the table can be provided. In a third embodiment, the connectability according to at least one column of the table can be provided. In a fourth embodiment, a connectability of all the rows can be provided. FIG. 25 is intended, overall, to show the optional possibility of the design of the measuring instrument assembly, in such a way that it is possible to purposely specify the combinations of the units 4, 5, 46 by means of the connecting means 47, 47′.
