Performance Ve rification
4. Power on the DUT
.
NOTE. Ensure the warm-up criteria has been met as described in the Performance
Verification Conditions.
5. Set the voltmeter as follows:
a. Set to measu
re DC volts.
b. Set to auto range.
c. Verify that the Math mx+b function is disabled (shift DCV), assuring that
volts are being read.
6. Set the electronic load as follows:
a. Set to Constant Current.
b. Set the to draw a consta nt current at the test current specified for the DUT
in the table for checking DC Voltage Accuracy With Remote Sense. (See
Table 15 on page 16.)
7. Set the channel under test (CUT) to the full scale (FS) output current.
8. Set the CUT to 0% of the FS output voltage (0 V).
9. Turn the DUT output on.
10. Ente
r the voltmeter reading into the ta ble for checking DC voltage accuracy
with remote sense. (See Table 15 on page 16.)
11. Inc
rease the CUT output voltage by 25% of the FS output voltage.
12. Repeat steps 10 and 11 until you complete testing at 100% of the FS.
13. Power off the DUT.
14. Disconnect the hook up wires from the Remote Sense connector and reinstall
the shorting clip on the channel you just tested.
15. Power on the DUT.
This completes the check for one channel. If needed, return to step 1 to run
through the check for the next channel.
