Press the key ,place the top of the meter close to the conductor, if the meter
detects AC voltage, the meter will The signal strength of , when the sensed
voltage is low , the screen signal will display low: , medium: ,
high: , and at the same time the buzzer emits alarm sounds of
different frequencies.
�NCV test
2. In the 10M range, it will take a few seconds for the reading to stabilize. This is
normal for high resistance measurements.
3. When the meter is open circuit or the resistance value of the measured object
is too large, the display will display "OL", indicating that the measured value
exceeds the range
Notice
●Even without indication, voltage may still be present. Do not rely on
non-contact voltage detectors to determine lead

influence of factors.
●When the input terminal of the meter enters the voltage, the buzzer will
also sound due to the existence of the induced voltage.
sound.
●Interference sources in the external environment (such as flashlights,
etc.) may falsely trigger the non-contact voltage detection.
