Equipment required
AC power source
High-current 18 AWG wire
Electronic load
Low-current 22 AWG wire
DC voltmeter
0.3 Ω resistors
To check DC voltage setting readback accuracy with remote sense:
1. Power off the device under test (DUT).
2. Remove the shorting jumpers that connect the output terminals to the sense terminals from the
output mating connector on the rear panel.
