Operating manual EMGZ308

2 Definitions
Offset:
Correction value for compensation of the zero point difference. Thanks to the offset, it is
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 (0...10V).
Strain gauge:
Electronic component that will change its resistance while its length has changed. Strain
gauges are used in the FMS force sensors for acquisition of the feedback value.
3 System components
