NCV NON-CONTACT (EF) VOLTAGE MEASUREMENTS

WARNING: Check the NCV function on a known live circuit before testing on a circuit
of unknown status.
1. Set the function switch to the
'NCV' icons will appear.
2. The non-contact voltage detection sensor is located at the
top of the meter. Place the sensor near the source of
voltage.
3. When the meter detects voltage it will audibly beep, the
display will blink red, and dashes will appear. The number of
dashes is proportional to the strength of the voltage source
as is the periods between audible beeps. Note that the
meter flashes red with each audible beep.
