6. Turn the DUT out
put on.
7. Enter the voltmeter reading into the table for checking current line regulation
under the mini
mum line for the CUT. (See Table 22 on page 22.)
8. Change the AC Power Source output to the voltage specified in the following
table.
DUT voltage selector
switch AC power source voltage Japan configured units
110 132 V 110
220 264 V 220
9. Enter the voltmeter reading into the Max line for the CUT. (See Table 22
on page 22.)
10. Change the AC Power Source output to the voltage specified in the following
table.

11. Enter the voltmeter reading into the Nom line for the CUT. (See Table 22
on page 22.)
12. Calculate the two values: Nom – Min and Max – Nom. Enter the values into
the appropriate columns. (See Table 22 on page 22.)
13. Select the largest of the two calculations from step 12 and enter the value into
the Largest column. (See Table 22 on page 22.)
14. Turn the DUT output off.
This completes the check for one channel. If needed, return to step 1 to run
through the check for the next channel.
