The NC4 voltage tester has two sensitivity ranges for accurately detecting the presence of AC voltages. The first will detect voltages between 50V and 1000V, and the second will indicate voltages between 12V and 1000V. Sensitivity can be set according to the application and when in high sensitivity mode the LED pulse double flashes.
The extended probe tip gives improved access and easier identification of live wiring.
