3-14
077102700/ July 2014
Check DC Voltage Setting Accuracy and Voltage Readback Accuracy
Equipment required
AC power source
High current hookup wire (boldline
connections)

connections)
DC voltmeter
For each channel sequentially.
1. Set up the equipment as shown.
Figure 1: Voltage accuracy, regulation, and protection test setup
Ensure the warm-up criteria have been met, as described in the Performance Verification Conditions
topic.
To assure accurate measurements, the voltmeter must connect as close as possible to the front
panel of the DUT. A solution is to use fork lugs between the electronic load and the DUT, and
banana plugs between the DUT and voltmeter.
