Abstract
An electronic caliper generates power for measurement operations. The caliper comprises a scale member, a slider, a signal processing portion configured to measure a displacement between the scale member and slider, a power generating arrangement attached to the slider comprising a gear assembly configured to rotate in response to a force provided through a power generating handle to the gear assembly by a user moving the power generating handle relative to the gear assembly, and a power generator coupled to the gear assembly and configured to rotate in response to force provided by the rotating gear assembly and provide power to the signal processing portion. The power generating arrangement generates power as the user moves the power generating handle, and the power generating arrangement contributes a motion resistance force component of at most 20N as the user moves the power generating handle with a maximum manual acceleration.
