Figure 5: Voltage accuracy, regulation, and protection test setup. The channel
1 test setup is shown.
2.
Set the voltmeter as follows:
a.
Set to measure 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.
3.
Set the electronic load as follows:
a.
Set to Constant Current.
b.
Set to draw a constant current at the test current speci

under test (CUT) in the table for checking DC Voltage Accuracy without
Remote Sense. (See Table 16 on page 17.)
4.
Set the CUT to the full scale (FS) output current.
5.
Set the CUT to 0% of the FS output voltage (0 V).
6.
Turn the DUT output on.
