1. AC Voltage Detection: When the probe end of the voltage tester is close to the AC voltage source, the red signal indicator flashes; the stronger the signal, the faster the red light flashes; at the same time, the beeping sound of the buzzer will increase in frequency with the enhancement of the signal strength
2. Flashlight illumination: LED illumination, convenient to detect voltage in dark environment
3. Circuit breakpoint detection: the pen stops flashing and buzzing when a breakpoint in the circuit is detected
4. Low battery warning: when the battery voltage is too low, the power indicator flashes, suggesting that the battery needs to be replaced in time
5. Auto Power Off: The voltage tester will automatically turn off after about 5 minutes of no signal detection or inactivity to prolong battery life
6. Portable pen clip design: portable and convenient for mobile measurement
7. High-strength shield: sturdy, wear-resistant, unbreakable
8. Inductive field, non-contact voltage detection (NCV): CAT-III 1000V overvoltage category, using non-contact high-sensitivity sensor for safe, fast and non-contact high-voltage detection
