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 zero exactly.
Gain: Amplification factor for the measuring signal. Use of an appropriate value will adjust
the force sensor signal to the tension feedback value exactly.
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.
Subprint: Electronic extension module which can be plugged to the main board of the
electronic unit if required. That way, the possibilities of the electronic unit can be extended
easily.
