I purchased the panel meter for AC current model number QB5735BW. I am able to power on the unit, however it appears to be reading in reverse/negative numbers. My suspicion is that I am wiring the load wire to the meter incorrectly. Is there a simple wire diagram for this unit? I am looking to purchase many more if i can get this right. My understanding was that this model does not need a shunt or ac coil to read current, is this true?

Just reverse the input wires should take care the "-"

Thanks for the reply. Could you look at the diagram in the link and tell me if its correct? This is an AC circuit.

Also, I wont need a shunt or anything else is that right?

Can you send me the link of the meter your purchase. I'm not sure which one you're asking question for.

Here it is.

Thanks again

This one already got a shunt built in. So, what you need to do is just to power the meter and put the meter input in series with the load and it should read the current properly. If it's showing "-", just reverse the input will fix the problem
