How to change Ampere meter analog when running?
application for control panel
the control panel still running, but I must change the ampere meter with ampere meter recorder.... if I disconnect it, the Amp meter will be burn or damage
The only practical way to change out an ammeter in a panel that has to remain powered up is to short across it with a wire that can handle the full load. This diverts current around your meter while you make the swap. Observe all safety precautions and have another person in the room standing watch over you when working on live circuits.
