Zero balance, cable and probe calibration
Calibrate the device during initial commissioning using the internal calibration.
During the probe calibration, the transition resistances in the device including the cable of the
connected probe are calibrated. You can change between a probe of 2 m and a probe of 5 m
without having to calibrate again.
If you use a 1-pin probe, place a bridge between the "Sonde / Probe" jacks "+" and "-".
Requirements
• Please observe the requirements for measuring [} page 71].
• Approved safety measuring lines
• The test sample is disconnected from the mains.
• The test sample is connected according to the connection diagram.
