EXTECH ET25 Voltage Tester
MODEL ET25 – Voltage Tester
- wire AC Grounded Outlets: Insert probes into the hot (narrow) and neutral (wide) slots of the receptacle. The tester will glow on a live circuit. To check to ground, insert one probe into the hot (narrow) side and the other into the “U” shaped ground. The tester should glow.
- wire AC Outlets: Insert probes into both slots of the receptacle. The tester will glow on a live circuit. To determine hot wire, insert one probe into one of the slots and touch the other probe to the metal mounting screw or metal plate. If the screw is grounded, the tester will glow when connected to the hot wire.
- wire 220V AC Outlets: Test for normal (110V) glow between round slot (neutral) and either hot side. The test will glow brighter when placed across both hot sides (220V).
