I have an cool large industrial AC ammeter that reads 0 to 1200 amps. I believe it was used in an old electrical transmission panel in an MCC, and was attached to a selector switch. I am speculating the selector switch could be used to measure the draw for different circuits - major electrical feeds to buildings or industrial plants, or maybe three large pieces of equipment
I'd like to use the meter for a display in a restaurant. How can I make it actually show a reading, so the patrons could use the selector swtich and register a change to the meter needle.
I think the best way would be to use a 9 volt battery or similar low volatge power source, to keep it safe and simple. So how can I get the meter needle to show a reading or move with such low voltage?
