Non-Contact Voltage Tester
The NCV sensor automatically recognizes the voltage. You just place the NCV inductive probe near the cables, cords, or outlet. Triple Volt Alert upon voltage detection: the NCV sensor changes to red and the buzzer sounds, the LCD screen display up to 8 bar graphs. In addition, the screen will light up red or green to distinguish between live/ neutral wire.
Null Wire Testing
The buzzer will give a slow alarm when the end of the tester is close to the object being tested. The red indicator light flashes slowly and the LCD shows green. This indicates that the tested line is a Null Wire
Live Wire Testing
The buzzer will give a quick warning when the end of the tester is close to the object being measured. The red indicator light flashes quickly, and the LCD shows red. This indicates that the line being tested is a live line.
Press for GFCI Test
This Electric tester tests GFCI devices by simulating ground fault conditions, which works on GFI outlets and confirms operation of the ground fault protective device. It tests standard outlets that are wired in parallel to GFCI outlets (multiple outlets in kitchen or bath, and outdoor receptacles require GFCI protection)
