chris a posted:Nick I am pretty sure your problem is that you need to use the second component with the hole in the center like Adriatic mentioned. The 2nd component, with the hole in the center, is most likely an amprobe designed to be dedicated to the amp meter.... like your using on your hand held meter. The AC hot to the center rail of your power district just needs to run through the hole, and not be connected directly to the back of the AC Amp Meter.... There should be a lead from the sensor probe that you connect to the meter itself. It's probably designed for higher voltage circuits that you wouldn't want running to the back of a panel.... 20 Amps at 240vac, or 460 vac is alot more energy (power) than 20 amps at 18 vac.
The amprobe should then be connected to the amp meter. If you're getting a current signal that's higher than your amprobe, it's because you are running the AC hot track power directly through the meter. I don't think you need to buy anything else, just try hooking up what you have without running the AC track power through the meter directly.
Chris --Yes you are correct as I have found out. However the "induction pick up coil" Will not work for low AC voltage So that set up will not work.It needs 100-200 volts. I did order these meters Below and I love them- they are built well-real heavy- are about 2 inches in diameter.perfect size easy to read and do not take up to much room on my control panel. You can run the hot side feed for each buss line (I have 4) right through them. And they are very accurate (I verified with my amp probe. Also the range is perfect pulling even just 2 amps shows up nice. Here is a link I think they were 15 bucks each. Thanks Nick
