"I have a bunch of adjustable DC power supplies which I need to adjust to 5 VDC output, but I suspect that when I just test it with multimeter it won&#39;t show correct voltage. Would would be a simple way to test it under load? Put some kind of resistor between power supply output and multimeter?"
