Testing
Put the sensor (1) up to a known AC power source to test the device. If it emits a sound and the LCD display (4) is green, the device can be used.
Usage
Put the sensor (1) up to a cable, a wire or a socket. The device will beep
fast and the LCD display (4) will be red if the signal is strong.
This means that the device has detected a live line. The device will beep slow
and the LCD display (4) will be green if the signal is weak.
This means that the device has detected a neutral or weak line.
Random beeps and flashes may occur due to detection of static charges.
Flashlight
Press (3) to turn the flashlight (2) on/off.
AC voltage measurement
Press and hold (5) to measure AC voltage, detect zero and live wires according to the voltage.
Continuity/positive measurement
Press and hold (6) to perform continuity test. Hold one end of the uncharged
wire with the left hand and put the sensor (1) up to other end of the wire. If
the buzzer emits sound and “– – C” is displayed, the wire is good. If the wire
is open, nothing will happen.
Press and hold (6) to perform positive measurement. Hold the negative pole
with the left hand and put the sensor (1) up to the positive pole of the
battery. The buzzer will emit sound and “– – P” will be displayed. If it is
connected reversely, nothing will happen.
Low battery indicator
When the voltage is below 1.2V, the device will display low battery icon. Immediately replace the battery after it happens.
