2.5 Cable Calibration
The resistance in the 4-terminal cables can be compensated for through the zero adjustment (0
ADJ) function. This should be performed when connecting a new cable to the instrument, when
the environment temperature changes ±5 °C, or when desired.
Complete the following steps to perform the cable calibration:
1. Warm-up the instrument for 30 minutes.
2. Short the 4-terminal connectors together (see Figure 11).
3. Ensure DRIVE+ is aligned with DRIVE- and SENSE+ is aligned with SENSE-.
4. Select a resistance range or AUTO to calibrate for all ranges.
5. Initiate the calibration function. Press 0 ADJ on the front panel.
6. Calibration time is affected by the SPEED, AVERAGE samples, and auto ranging.
