4.3 Connection Variants
Two connection Types can be used when measuring with strain gauges:
4-wire measurement:
The advantage of this variant is that a 4-pin connector cable can be used for the strain
gauge. The voltage drop over the circuit for the bridge voltage supply however, cannot be
compensated.
6-wire measurement:
This configuration provides the advantage of voltage compensation using the bridge voltage
supply measurement on the strain gauge directly.
