Compensation of
cable resistances
measurement mode:
voltage measurement with
adjusted supply
3-wire circuit:
single sense wire:
sensing of return line only
( –VB: supply ground)
physical adjustment of voltage (+VB)
Provided for 5 V.
Prerequisites:
1) symmetrical feed and return lines,
2) identical wires for all channels,
3) representative measurement at
Channel1
Compensation of
cable resistances
measurement mode:
bridge measurement, strain gauge
3-wire circuit:
single sense wire:
sensing of return line only
( –VB: supply ground)
voltage drops dynamically
monitored and numerically
compensated
Provided for 2.5 V, 5 V and 10 V.
Prerequisites:
1) symmetrical feed and return lines
differing cable length for individual
channels allowed

With option ±15V the quarter bridge is not supported, because the ¼ bridge pin is used for–15V
Also the ground referenced current measurement no longer applies
2
The precision of the bridge measurement is not affected by actual precision of the bridge supply. The current value of
the bridge supply is continuously monitored and compensated.
