Check DC voltage line regulation
This check procedure uses the same test setup as the previous procedure. (see
accuracy without remote sense and voltage readback accuracy
1. Change the AC Power Source output to the minimum voltage specified in the following table.

Ensure the warm-up criteria has been met as described in the Performance Verification Conditions.
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 specified test current.
