Definitions
Offset:
Correction value for compensation of the zero point difference. The offset
adjustment ensured that a force of 0N will generate a signal of 0V exactly.
Gain:
Amplification factor for the measuring signal. Use of proper value will set the
measuring range of the sensor exactly corresponding to the signal output range.
Strain gauge:
Electronic component that changes its resistance when it is extended.
Strain gauges are used in the FMS force sensors to gather the feedback value.
