Maintenance masters and electricians DIY enthusiasts must have the magic TOOL!
√ It is a must-have for electricians, repairmen and DIY enthusiasts!
√ A slide can find where the wires are broken!
√ One screw can easily remove all kinds of screws.
√ Also with a digital screen voltage, work safer!
Core functions, to solve daily problems
1. Non-contact Voltage Detection
Close to the top of the wire green light automatically bright shows that there is electricity around, without touching the line on the early warning of danger!
2. Neutral/live Line Recognition
When the screwdriver head touches the wire:
◦ green light → neutral line ( safety)
◦ red and green lights flash → LIVE line (be careful!)
3. Precise Location of Broken Point
Can't find the broken wire ? Slide the cutter head along the wire:
◦ The screen number suddenly goes to zero → the break point is here!
4. Smart Screwdriver
Phillips/CROSS head version:repairing cell phones, installing sockets, screwing small screws on circuit boards (with strong magnetic suction head, screws do not fall off)
FLAT head version: dismantle home appliances, repair switches, deal with rusty screws (non-slip cutter, bite firmly)
Who needs it? Where to use it?
- Home emergencies: quickly find out which outlet is leaking when you trip a switch.
- Installation and modification of electrical wiring: detect the voltage of wires before installation.
- Appliance repair: repair air conditioning / washing machine, while measuring the power while removing the screws, no need to change tools back and forth!
- Electronic DIY: assemble smart homes, drones, precise operation of small screws Two types of cutter head for your choice.
A variety of functions for you to choose from, to meet your different needs, a new design, safe power measurement tool.
Product self-test
The product will only light up green when a circuit is formed at both ends of the product.
Circuit Break-point Detection
The so-called breakpoints cannot be directly measured and it is necessary to find a suitable area to measure them. For example, when measuring a wire, if the test pen is adjacent to the wire, the green light will light up. The green light on indicates the electric field induction area. In this induction area, the test pen will light up with a green light, and the breakpoint will be located at the boundary of the induction area. There are various types of wires and different lines with different measurement results, which can be discovered with a little exploration
Non-contact AC detection When the screwdriver induces the voltage signal around the socket, the green light flash.
Product Information Introduction
Battery Replacement
▲ During the self-check test, if the green light is not on or off, it means the battery voltage is insufficient or the power is low. Please replace the battery in time.
▲When replacing the battery, pay attention to the positive and negative polarity, and place it according to the polarity label on the circuit board corresponding to the battery polarity.
Smart Digital Screwdriver Bit Display
Two different heads for you to choose from, a cross head and a FLAT head.
Live / Neutral Line Detection
Live Line Detection: When the screwdriver head touches the power supply, the red and green LED will light up at the same time, indicating that it is live line (Voltage > 70V, red LED will light up and the buzzer will sound).
Neutral Line Detection: When the batch head touches the power supply, the green light will be on, indicating neutral line or ground line.

Ideal for Electrical repairs, installations, HVAC work and home safety checks, industrial equipment maintenance.
Using Tips:
*Before use, visually inspect the test pen housing for cracks or ruptures, as well as for moisture or water ingress. Only after passing the inspection can it be used. If you suspect any issues please immediately send the test pen for repair.
*Before use, perform a self check test. Hold the screwdriver with one hand and touch the electrode with the other hand. If the green light is on, it indicates that the test pen is functioning properly and can be used. If the green light is not on, please do not use it.
*Before use, test on a known live power source to ensure that the product is in good working condition.
*When using the voltage measurement function, it is prohibited to touch the metal knife bar at the front end with your hands, otherwise it may cause personal electric shock accidents.
*Do not apply voltage exceeding the rated voltage marked on the tester. Be particularly careful when testing AC voltages above 30V to prevent electric shock hazards.
*Comply with local and national safety regulations.
*Use appropriate protective equipment in accordance with local or national regulatory requirements.
