15. Use of Test Leads

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.

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 auto-

off function, press and hold the SELECT button in the off state and turn on the

meter.
