g) Non-contact AC voltage test “NCV”
Make sure that all measuring sockets are unoccupied. Please remove all measur-
ing leads and adapters from the measuring
device.
This function only serves as an aid. Prior to
performing work on these cables, you must
perform contact measuring operations to
check for the absence of voltage.
Test this function beforehand on a known
AC voltage source.
1. Set the function dial to
NCNNn f
NCV
2. Short press the SEL button 1x to select non-
contact voltage test, “EF” and “NCV” will show on
the display.
3. Guide the non-contact voltage sensor area to the test location (max. 5 mm). For twisted
cables, it is recommended to touch the cable with the end of non-contact voltage sensor.
- If AC power is sensed, the tri-color indicator LED will light up and the buzzer will sound.
- The higher the voltage, the higher the frequency at which the buzzer will beep.
- The tri-color indicator LED will change from green to yellow to red as the voltage in-
creases.
4. When finished measuring, switch the power OFF.
