Combines a GFCI Tester and AC Line Splitter in one tool so that you can check outlet wiring, measure voltage, and use your clamp meter to measure current up to 15A without breaking the circuit.
Use a clamp meter (sold separately) around the 1x position for a direct current reading; Use the 10x position to display low current readings multiplied by 10.
At the push of a button, you can test GFCI for proper operation and also detect faulty wiring in 3-wire receptacles.
The lights display 5 wiring faults: Open Ground, Open Neutral, Hot/Ground Reverse, Open Hot, Hot/Neutral Reverse.
There is an easy to read fault label on both sides for receptacles with ground up or ground down installation.
