g) Non-contact AC voltage test “NCV”
Make sure that all measuring sockets are unoccupied. Please remove all measuring
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, “EF” and
“NCV” will show on the display.
2. 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 volt-
age sensor.
- If AC power is sensed, the tri-color in-
dicator 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 volt-
age increases.
3. When finished measuring, switch the power
OFF.
