OPERATING MANUAL
NON-CONTACT VOLTAGE MEASUREMENT (NCV)
1. Switch the function dial to
NCV
position.
2. In NCV sensing level 2 (default, LCD displays “EFHI”), the voltage range is 48V–220V.
Place the upper left corner of the multimeter near the live AC power cord.
If the voltage of the measured power cord is in the range of sensing level 2, the yellow
indicator will start flashing and the buzzer will beep intermittently.
According to the intensity of the induced voltage, the yellow indicator flashes with varied
frequencies (flashes fast when the intensity is strong), and the buzzer beeps with different
intermittent time (the intermittent time is short when the intensity is strong).
The LCD displays the induction intensity from weak to strong by “-”, “- “, “- “, “---·- “.
If the measured power cord is >220V, the red LED will be on.
3. If the measured power cord voltage is <48V, users need to short press (<2s) the SEL/REL
button to switch to sensing level 1 (LCD displays “EFLo”). If the voltage of the measured
power cord is in the range of sensing level 1, the green indicator will start flashing and the
buzzer will beep intermittently.
According to the intensity of the induced voltage, the green indicator flashes with varied
frequencies (flashes fast when the intensity is strong), and the buzzer beeps with different
intermittent time (the intermittent time is short when the intensity is strong).
The LCD displays the induction intensity from weak to strong by “-”, “-·- ,· - -”, “- --· “.
4. Short press (<2s) SEL/REL button again to switch to sensing level 2 (LCD displays “EFHI”)
measurement.
NOTE:
•
The sensing level varies with the distance between the sensing part and the measured AC
power cord.
•
The sensing voltage level is for reference only and no specific measurement is made.
The frequency of the induced voltage is applicable to 50Hz/60Hz.
•
If there is no indication, voltage could still be present. Do not rely on the detector with
shielded wire.
