Hugh's right, those meters need a isolated power supply. There is a article on my site about using them.

If you have a old unused network card you can use the inverter to provide the isolated power.

glenn-

thanks for the info! very nice explanation and diagram! i never knew that was on your site. your meter required 9 volts, so i see how you got that out of the computer chip/regulators/caps/ect. mine will work with anywhere from 7-30 volts. is there an easier way to get "isolated" power from my bank without having to adjust for voltage? i don't have mounds of old chips and electrical parts sitting around, but do have a radio shack close.

thanks

For testing.. just got to R.Shack and pick up a 9 volt batter snap on battery and connector, wire the shunt as others have said. Once you establish that the meter is ok, you can worry about powering it from another source.

I have one of the similar meters, wired for portability with some banana posts running off a 9 volt battery.
