Two sensitivity levels, with audible and visual indication
Flashing LED indicates sensitivity range, down to 12 V AC, or standard range above 50 V AC
Differentiates hot from neutral in AC outlets
Low pass filter reduces false indications
The testo 745 non-contact voltage (NCV) tester quickly checks for the presence of voltage in AC powered systems. It can be safely used up to 1000 V AC. When AC voltage is detected, the testo 745 gives an indication, by flashing its red LED tip, and buzzing its internal audible buzzer. You can easily determine the hot and neutral legs of an outlet, without the time consuming and risky removal of the outlet from the outlet box.
