Product Description

Getting Started

Open the battery compartment cover (7) and insert AAA battery according to the correct polarity. Close the cover.
Press and hold (3) for 3 seconds to turn the device on/off.

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.
