A: The ET40 tests DC voltage as low as 1.5V and tests AC voltage 12-240VAC.
A: The ET40 can be used to test voltage in a light socket.
A: Yes, ghost voltage can impact most electrical testers/meters. The only way to get around ghost voltage is to get a meter with LoZ (low impedance) mode such as Klein Tools model # MM700, CL700, or CL800.
A: Yes, the ET40 can test voltage on light switch wires.
