Check DC Voltage Line
Regulation
This check procedure uses the same test setup as the previous procedure. (See
Figure 5.)
For each channel sequentially.
1.
Change the AC Power Source output to the minimum voltage speci
fi
ed in the
following table.
NOTE.
Ensure the warm-up criteria has been met as described in the Performance

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 the speci
fi
ed test current.

4.
Set the channel under test (CUT) to 100% of the full scale (FS) output current.
5.
Set the CUT to 100% of the FS output voltage.
6.
Turn the DUT output on.
