A deformation detection apparatus includes a cell movement-control assembly to handle a linear motion and a rotational motion of a battery cell, a body that supports the cell movement-control assembly, a digital micrometer, and control circuitry. The control circuitry controls a displacement of the battery cell between a first position and a second position along a longitudinal axis through a scanning region of the digital micrometer and a plurality of rotational positions of the battery cell at a plurality of charge states and a plurality of discharge states. The control circuitry measures a plurality of outer diameter values of the battery cell for a plurality of linear positions and a plurality of rotational positions along the longitudinal axis of the battery cell and determines a change in a geometrical shape (deformation and/or strain) of the battery cell for the plurality of linear positions and the plurality of rotational positions.

An apparatus reads a value measured with an analog measuring tool. The apparatus includes an imaging unit for obtaining a captured image of the analog measuring tool that is indicating a measured value, a retaining unit for retaining a 3D model of the analog measuring tool, a matching unit for specifying a 3D model matching the captured image, a guidance unit for outputting guidance information for correcting orientation of the analog measuring tool based on the matched 3D model, a reading unit for reading the measured value from the captured image to generate a measurement result, and an output unit for outputting the measurement result.

A parameter setting method of a measuring instrument includes: reading model information, measurement-related setting items, and parameters corresponding to the setting items, which are stored in the measuring instrument, and temporarily storing the read data in a storage unit of a computer; displaying an appearance image of the measuring instrument corresponding to the model information on the screen and displaying icons for selecting an operation on the screen at predetermined positions of the appearance image on the screen in correlation with each other; displaying the setting item, which is able to be selected by an operation in the measuring instrument relevant to the predetermined position corresponding to the selected icon, on the screen when selection of the icon is received; receiving changing of the parameter corresponding to the setting item using the computer; and transmitting the changed parameter from the computer to the measuring instrument.

A measuring instrument includes a measuring unit, an electric component unit and a pin jack. The electric component unit includes a signal processing part. The signal processing part is configured to calculate a measurement data based on a detection signal obtained by the measuring unit. The pin jack is provided in the electric component unit.
