h) Contact-Free AC Voltage Detection “NCV”
The “NCV” detector is placed on the top of the housing and reacts only to alternate
voltages between 200 and 1000 V/AC.
This function is only used for quick search for alternate voltage-conducting lines and
cables. For work at the power lines, freedom from voltage must be verified with the
traditional contact test method (phase tester)!
• The measuring leads are not required.
• Turn on the DMM and select any measuring function.
Contact-free voltage detection is active in all measur-
ing functions.
• Move the DMM with the “NCV” sensor (upper hous-
ing edge) along the test object. The detection depth
reaches from approx. 3 cm at 230 V/AC to approx. 8
cm at 1000 V/AC.
• Where a live line is discovered, the “NCV” lighted dis-
play (13) lights up.
• Switch off DMM after measuring.
Shielded lines, lines that are too deep or twis-
ted wires may negatively influence the display.
