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.

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.
