A method system of reducing operator-induced error in measurements comprises a measurement tool, such as a diameter gage, that is configured to communicate electrical signals representative of measurements to a computing device, which is configured to receive the signals and to determine a value for the measurement without the operator having to interact with the tool to zero the gage, acquire the data or transmit the data.

A brake wear gauge assembly includes a plurality of wires that is each comprised of a bendable material such that each of the wires is retained in a desired shape for guiding between a brake rotor of a vehicle and a brake pad of a vehicle. A ring is provided that has each of the wires movably disposed thereon thereby facilitating the plurality of wires to be portable. A plurality of feeler gauges is each coupled to a respective one of the wires. Each of the feeler gauges can be inserted between the brake rotor and the brake pad and each of the feeler gauges has a unique measuring thickness with respect to each other. In this way the plurality of feeler gauges can measure a variety of distances between the brake rotor and the brake pad.

A mechanical gauge includes a stock panel with a first measurement scale, and a slide movably arranged relative to the stock panel. The first measurement scale has a series of marks spaced apart at regular intervals within a region of interest. The slide includes a second measurement scale adapted to selectively overlie the first measurement scale within the region of interest. The second measurement scale has a second series of marks spaced apart at regular intervals corresponding to the first series of marks of the first measurement scale. An elongated measurement probe is affixed to the slide and adapted for selectively extending into a groove formed in the tread of the vehicle tire.

An apparatus for checking the diameter of crankpins (15) of a crankshaft in orbital motion about a geometrical axis in a numerical control machine tool includes a V-shaped reference device (10), a measuring device (6) and a support device (4) fixed to the tool holding slide (2) that movably supports the reference device and the measuring device. A control device (50) for controlling automatic displacements of the apparatus towards and away from a checking condition, includes a programmable electric motor (60) and a transmission mechanism (62). The programmable electric motor is programmed to define a start position in which the automatic displacement of the apparatus away from the checking condition can be stopped, for instance a rest position or an intermediate position between the rest position and the checking condition. The programmable electric motor is also programmed to define a displacement speed and a checking method includes steps for controlling the automatic displacements towards the checking condition.
