2 In the 10M range, it will take a few seconds for the reading to stabilize, This is
normal or high resistance measurements
3. When the meter is open circuitor the resistance value of the measured object
is too large, the display will display "OL indicating that the measured value
exceedsthe range
NCV TEST
Pressthe BE key place the top of the meter close to the conductor, if the meter
derects AC voltage, the meter will The signal strength of ‚ when the sensed
voltage is low , the screen signl wil display law: MIE ‚ medium: WINN
high: „and at the same time the buzzer emits alarm sounds of
different frequencies.
@even without indication, voltage may still be present. Do not rely on
non-contact voltage detectors to determine lead
Whether there is voltage on the ine. Probing operations mayvary by socket
design, Insulation thieknass and type, ete
influence ef factors.
@uhen the input terminal of he 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 flashlight,
ete.) may flsely trigger the non-contact voltage detection.
