i) 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 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 frequen-
cy at which the buzzer will beep.
- The tri-color indicator LED will change from
green to yellow to red as the voltage increases.
3. When finished measuring, switch the power OFF.
12. Additional functions
Button press:
• Short press = <2 sec.
• Long press = >2 sec.
a) Access sub functions
Several measuring functions are assigned sub functions, and are marked in red around the
function dial. Short press the SEL button to cycle through each sub function.
