To check DC voltage setting accuracy without remote sense:
1. Set the voltmeter as follows:
Set to measure DC volts.
Set the current range to autorange.
2. Set the electronic load as follows:
Set to constant current (CC) mode.
Set to draw a constant current at the test current specified for the DUT in the DC voltage setting
accuracy without remote sense table.
3. Set the DUT to the full-scale output current.
4. Set the DUT to 0% of the full-scale output voltage (0 V).
5. Turn the DUT output on.
6. Enter the voltmeter reading in the DC voltage setting accuracy without remote sense table.
7. Increase the DUT output voltage by 25% of the full-scale output voltage.
8. Repeat steps 5 through 8 until you complete testing at 100% of full-scale output voltage.
