2) Press NCV key, put the NCV sensor close to the measured
cable, the meter could detect if the measured cable is >90V
AC voltage or not. When the meter detects AC voltage, the
meter buzzer alarms and the backlight flashes.
Note:
1) Even there is no alarm indication, the voltage might still exist.
Do not judge if there exist voltage or not in the cable relying on
non-contact voltage detector. The detection operation might
be affected by various factors such as the socket design and
insulation thickness types are different and so on.
2) In NCV detection mode, the meter will not measure the
voltage, resistance and current at the same time.
