When I power up my Bench power Supply (no matter what voltage) with no load attached the Ampmeter always says 5mA are flowing . After around five minutes of usage this current disappears. Any ideas what could be the problem?
Unless the ammeter has a 5mA precision, not unreasonable for 1A or 5A meter.What's the model of the power supply? Can you upload a picture? Sometimes these kind of variations are related to the display precision and the tolerance allowed. But 5 mA is too big to consider it a margin of error.
