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
).
Step 2. Set the external supply as follows: Voltage setting = (0.9 V + 0.08 * maximum output voltage of
the unit under test). The voltage must be within 10% of this value. Current limit = (0.95 * rated output
current of the unit under test). The current limit must be within 2% of this value.
Step 3. Select the resistance bottom-out calibration. Calibration takes approximately 5 seconds.
