Step 3. Select the first calibration point. Measure the voltage across the sharing connector and enter
the data.

Display shows: “Enter P1 measured data”. Enter the data from
the external DVM. This should be about -1 volt. Press Enter
when done.Press Back to finish.

Step 4. After the calibration completes, disconnect the voltmeter and short.
Resistance Bottom-Out Calibration
This procedure calibrates the minimum voltage that can be achieved while sinking current.
Step 1. Connect an external power supply to the + and - output terminals (see Cal Setup E).
Step 2. Set the external supply as follows: Voltage setting = (0.9 V + 0.08 * rated output voltage of the
power supply) volts. The voltage must be within 10% of this value. Current limit = (0.95 * rated output
current of the power supply) amps. The current limit must be within 2% of this value.
Step 3. Select the resistance bottom-out calibration. Calibration takes approximately 5 seconds.
