1. Use the DC adjustable voltage regulator to connect to the P-N terminal of the machine
under test, and hang the multimeter pen on the P-N, and set the multimeter to DC voltage
(DC); note that the software voltage correction factor is 100% before testing. Compare the
value displayed by multimeter and keyboard
2. Measure the voltage at this point of the VPN: (get the VPN voltage from the voltage
scaling relationship)
