The NCV function (non-contact voltage detection) 

enables the contactless detection of a current on 

conductors. The NCV sensor is located on the top of 

the clamp.

Always  test  the  NCV  function  first  on  a

known current source to avoid incorrect 

measurements. There is a risk of an electric 

shock in the event of incorrect 

measurements.

Proceed as follows:
1.  Turn the setting wheel to NCV. < NCF > appears 

on the LCD display.

2.  Place the NCV sensor next to a conductor with a 

gap of 8 – 15 mm (figure 2). The current clamp will

send the following signals if a current is detected:

 - For voltages ≤100 V/AC, < EF > will appear on the

LCD display.

 - For voltages >100 V/AC, the device will beep.

•  Turn off the current clamp before cleaning and remove it from the measured object.
•  The current clamp does not require maintenance except for occasionally changing the 

batteries.

•  Under no circumstances should you service any of the components in the interior of the 

device. For this reason, never open the product (except for inserting/changing the batteries 

as described in these operating instructions).

•  Repair or maintenance work must only be carried out by a specialist or a repair centre.
•  Always clean the current clamp with a clean, lint-free, antistatic and slightly damp cloth.
