Non-Contact Smart Sound And Light Sensing Measuring Electric Pen

1. Material: ABS
2. Weight: about 30g/piece
3. Size: about 14.3x2x1.25 cm/piece
4. AC voltage test: 70-250V AC
5. DC voltage test: DC within 250V
6. Polarity test: 1.2-36V DC
7. Power supply: comes with 2 AG13 1.5V button batteries
8. Features: use ABS insulating material to prevent electric shock, sensitive probe, sound and light double alarm, inductive alarm detection

Features:
1. Inductive alarm detection: adjust to L or H gear, when the nearby AC voltage is detected, the green light will be on and the alarm will sound
2. Neutral line detection (contact detection): set the gear to O, when the test pen is inserted into the hole, the red light is on, it is the live line
3. Live wire detection (contact detection): set the gear to O, when the test pen is inserted into the hole, the red light does not light up, it is the zero line
4. Line breakpoint search: adjust to H position, test along the line with the electric test pen, when the green light is off, the buzzer will stop, it is the breakpoint position, and the hand needs to touch the metal contact to detect the breakpoint
5. Battery detection: turn to H position, place your finger on the touch pole, and place the pen tip on the positive electrode of the battery. The red light is on to indicate that the battery is full, and the light is off to indicate that the battery is dead
6. Self-check battery: any position, hold the pen tip in one hand, press the touch electrode in the other hand, the red light on indicates that the battery is full, and the off light indicates that the battery is dead and need to be replaced
7. Leakage inspection: set to O gear, and the pen tip is in contact with household appliances (do not touch the touch pole). The red light is on. The electrical equipment is leaking, and it is not on and there is no leakage.
