Product description
The HT91A is an intelligent voltage tester pen capable of detecting AC voltage from 12V to 400V. It features easy operation, high accuracy, and is designed for electrical technicians and industrial electricians for wiring tasks.
1. Non-contact voltage detection (NCV): Equipped with a built-in sensor, it flashes a red light and emits a sound alarm when it detects nearby AC voltage. The alarm intensity increases with signal strength. Additionally, when the signal is strong, the display shows "---U" and "---HI," helping locate breakpoints in wires.
2. Interchangeable screwdriver head design: Comes with a slotted and Phillips head to meet voltage testing and tightening needs.
3. AC voltage and live/neutral wire detection: Press the voltage button and insert the screwdriver into the AC socket to obtain voltage values and differentiate between live and neutral wires based on voltage levels.
4. Battery positive pole detection: Press the CONNECT button on the pen with your right hand, touch one end of the battery with your left hand, and then touch the positive pole of the battery with the pen probe. If normal, the display shows "———p" and the buzzer sounds; if reversed, there is no response.
5. Dual alert system: Both the display screen and buzzer indicate voltage measurements, providing a dual reminder. When the backlight turns red, it indicates potential danger, requiring caution.
6. Auto power-off: The voltage tester automatically shuts off after about 5 minutes of inactivity or signal detection to prolong battery life.
