NON-CONTACT AC VOLTAGE DETECTOR
The EX310 can detect the presence of AC voltage (from 100 to
600VAC) simply by being held very near to a voltage source.
WARNING: Test the AC voltage detector on a known live circuit
before each use.
WARNING: Before using the meter in the AC Voltage Detector
mode, verify that the battery is fresh by confirming characters
appear on the LCD when the function dial is turned to any
position. Do not attempt to use the meter as an AC Voltage
Detector if the battery is weak or bad.
NON-CONTACT VOLTAGE (NCV)
The NCV function works on any rotary
switch position.
1. Test the detector on a known live circuit
before use.
2. Press and hold the NCV button for the
duration of the test. The meter will beep
once when the button is pushed.
3. Hold the top of the meter very close to
the voltage source as shown.
4. If voltage is present, the rim of the LCD
display will flash a bright orange and an
audible warning will sound.
