2. Set the voltmeter as follows:
a. Set to measure DC volts.
b. Set the current range to auto range.
c. Calculate the amperes (instead of volts) by multiplying the voltmeter reading result by 1/R.
3. Set the electronic load as follows:
a. Set to constant voltage.
b. Set to the specified voltage for your device under test (DUT) (see
(on page B-13)).
4. Set the device under test DUT to 0% of the full-scale output voltage.
5. Set the DUT to 100% of the full-scale output current.
6. Turn the DUT output on.
7. Enter the voltmeter reading in the
(on page B-13) table.
8. Change the AC power source output to the voltage specified in the following table.
DUT voltage selector switch

11. Enter the voltmeter reading in the Nom column for your product in the
(on page B-13) table.
12. Calculate the two values: Nom
– Min and Max – Nom. Enter the values in the appropriate
(on page B-13) table.
13. Select the largest of the two calculations from step 12 and enter the value in the Largest column
(on page B-13) table.
14. Turn the DUT output off.
