6. Enter the voltmeter reading in the minimum load column of the table for checking DC Voltage
Load Regulation for the channel under test.
7. Increase the electronic load to the reference load test current value.
Channel
Test current
Channel 1
1.5A
Channel 2
1.5A
Channel 3
1.5A
8. Enter the voltmeter reading in the reference load column of the table for checking DC Voltage
Load Regulation for the channel under test.
9. Increase the electronic load to the maximum load test current value.
Channel
Maximum load test current
Channel 1
3A
Channel 2

10. Enter the voltmeter reading in the maximum load column of the table for checking DC Voltage
Load Regulation for the channel.
11. Calculate the three values: Ref – Min, Max – Ref, and (Max – Ref)/0.98. Enter the values in the
appropriate columns.
12. Enter the largest of the three values calculated in step 11 into the Largest column.
This completes the verification procedure for one channel. If needed, return to step 1 to run through
the procedure for the next channel.
