1) Turn the function dial to the NCV position, and bring the NCV sensor close to the wire under
test.
2) If there is AC voltage or electromagnetic field in the space, the LCD will display the sensing
intensity from weak to strong by "—". At the same time, the buzzer will beep intermittently and
the LED indicator light will be on. When no voltage is sensed, the LCD displays "EF".
During measurement, if there is no operation of the function dial or any button for 15 minutes,
the meter will automatically shut down to save power. Users can wake it up by pressing any
button (except FLIGHT button). To disable the autooff function, press and hold the SELECT
button in the off state and turn on the meter.
1) TESTING IN CAT III/CAT IV MEASUREMENT LOCATIONS:
Ensure the test lead shields are pressed firmly in place. Failure to use the
CATIII/CATIV shields increases arc-flash risk.
2) TESTING IN CAT II MEASUREMENT LOCATIONS:
CAT III/CAT IV shields may be removed for CAT II locations. This will allow testing on
recessed conductors such as standard wall outlets. Take care not to lose the shields.
Warning: Before opening the rear cover of the meter, remove the test leads
to avoid electric shock.
GENERAL MAINTENANCE
1) The maintenance and service must be implemented by qualified professionals or designated
departments.
