E. Other Features
Non-Contact Voltage (NCV)
Measurement Procedure:
Remove the test leads and temperature probe prior to using the
NCV feature.
1. Turn the meter on to any range.
2. Press and hold the NCV button.
3. Put the arrow marked on the jaw close to the wire under
4. If voltage is present the 270 will beep and the NCV LED
5. If voltage is not detected, confirm the result by perform-
24
Never rely on the non-contact voltage function only. If a volt-
age is not detected, confirm there is no voltage by performing
a voltage measurement with the test leads. Failure to do this
could result in injury. The non-contact voltage feature works
best when testing single wires. Make sure the test leads and
temperature probe are disconnected while using the NCV fea-
ture.
