Non-Contact Voltage Detector - Extech Instruments EX360 User Manual

Non‐Contact Voltage Detector
WARNING: It is possible for voltage to be present in a circuit even if the meter does not
beep or light the NCV LED lamp at the top of the meter. Always verify meter operation on a
known live AC current circuit and verify that the batteries are fresh before use.
The audible beeper sounds and the LED lamp at the top of the meter lights when the meter
senses an electrical voltage field.
If the meter does not emit a tone or light the LED in this mode, there is still the possibility that
voltage is present. Please use caution.
1. Turn the function switch to the NCV position to access the Non‐Contact Voltage Detect
mode.
2. Use the Lo/Hi button to select low sensitivity (160 to 1000V) or high sensitivity (80 to
1000V). The display will show Lo for low sensitivity or Hi for high sensitivity mode.
3. Note the voltage detection display icon on the display when in this mode.
4. To test, place the meter near a source of electrical energy. Note that the tip of the meter
offers the highest sensitivity.
5. Note the audible tone and the LED light when a source of electrical energy is detected.
