Clamp Around Only ONE Conductor To Measure AC Current

Elec Engr here. For those who are using this meter to measure AC current and getting very low numbers, you are very likely clamping around the hot wire as well as the return neutral wire (the two together, at the same time), and are thus measuring only the common mode current, which should be very low. In order to measure the current passing through your appliance, you need to clamp around only one conductor. If your appliance has a power cord of two conductors with a common jacket or sheath, or is in zip-wire format, you need to break out one of the conductors and clamp around just one conductor. It doesn't matter if you clamp around the hot or the neutral - you should get the same number in both cases.

When I do current testing of an electrical appliance, I have a 1 ft extension cord that I've modified to break out the insulated hot and neutral wires. I then insert this extension cord between the wall outlet and the appliance, so that I can measure current delivered to the appliance without modifying the cable the emanates from the appliance. DO NOT HAVE ANY BARE WIRES, everything should be insulated.

As for what I like about the meter, it has a good build feel to it and measures AC currents down to 5 mA, which is great for working on very low current AC control circuits.

Very nice meter

This thing is made for working on AC units. for the price you are getting a nice meter that will do most all things you'll need.
