Measurements are made directly on rolling stock without wheel set roll-out.

The measurement of the diameter is performed according to the "three points" technique, without the complete wheel coverage. The gauge contains numeric display to show the value of the wheel diameter. IDK-BT gauge contains Bluetooth interface for transfer results into wheel-set wear database management system.
