Hi everybody,
I use the Owon P4305 DC power supply for about 1 year, this power supply has a hidden menu to recalibrate the V, A parameters. If recalibrated with a high-precision device, the Owon P4305 also has a fairly high accuracy. I tried calibrating with a 34410A multimeter and the results were better than expected, the P4305 holds the voltage very well both at no load and at full load.
I'm curious if the power supply from other brands of Keysight, Tek, Siglent, Rigol... users can self-calibrate V, A during use, both official and hidden menu ?
