Electronic Caliper Configured to Generate Power for Measurement Operations

An electrically powered caliper configured to generate power for measurement operations, the caliper comprising:

• a scale member;
• a slider;
• a signal processing portion configured to measure a displacement between the scale member and the slider;
• and
• a power generating arrangement fixed relative to the slider comprising:
• a power generating 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,
• wherein:
• the power generating arrangement generates power as the user moves the power generating handle;
• and
• the power generating arrangement is configured such that it contributes a motion resistance force component of at most 20N as the user moves the power generating handle with a maximum manual acceleration.
