4.4 Preparation before measurement
4.4 .1 Tap the power source button to power on. If the battery
voltage is low (about 2.8V), the monitor will display " "
symbol, then should charge. Press the power button again
to turn it off.
4.4 .2 When the instrument is not measured, the instrument enters
the automatic scanning state and the instrument displays
4. 5 Non-contact Voltage Detection (NCV)
4.5.1Touch the NCV key to enable the NCV function, and the
instrument displays NCV
4.5.2The NCV sensor is placed close to the measured wire, and the
instrument can detect whether the measured wire is gt. 90V
ac voltage. When the meter detects the ac power, the meter
buzzer alarms and the LCD analog bar displays the induction
intensity.
Note:
1) Voltage may still exist even if there is no alarm indication. Do not
rely on contactless voltage detectors To see if there's a voltage
on the wire. Probe operation may depend on socket design,
insulation thickness Different types of factors such as the impact.
2 ) In NCV mode, the meter does not measure voltage, resistance,
and current at the same tim
