How to Use an Amp Probe Meter

Amp probe meters are used to measure currents and continuity inside of electric wires and cables around the house.
These meters can detect wires and cables that have faulty continuity, which means they should not be used and could cause appliances and currents to short circuit. Amp probe meters are very easy to use, and you do not need to be an electrician in order to use one correctly. Depending on the type of current and wire you are testing, you will need to set the amp probe to a 0-10 or 0-20 amp scale. A local electrician could advise you about setting your amp probe meter.

Step 1

Press the button on the amp probe meter to zero it. Set the meter to either a 0-10 or 0-20 amp scale.

Step 2

Clip the meter onto the wire or cable once the screen reads "0."

Step 3

Plug the wire or cable into an outlet and record the measurement taken by the amp probe meter. If the amp probe meter still reads 0, there is a break somewhere in the circuit and you should hire an electrician to correct this problem, as it requires professional experience.
