1. Material: ABS
2. AC voltage range: non-contact measurement 30~1000V; contact measurement 11V~450V
3. Frequency: 50~60Hz
4. Alarm mode: screen backlight color change + sound
5. Power supply: two AA batteries (not included)
6. Identify the neutral and live wires: the live wire has a large electric field strength or a high voltage value
7. Induction sensitivity indication: three-grid scale indication: "-" weak electric field; "--" medium electric field; "---" strong electric field
8. On-off buzzer: the wire is connected, the screen displays 0, and the buzzer sounds
9. Battery undervoltage: when in use, the screen displays "LO" to indicate insufficient power and the battery needs to be replaced
10. Safety level: CECAT.II 1000V/CATIV 600V
11. LCD backlight display, the backlight will automatically turn on 3 seconds after power on, and the screen value can be clearly seen in a dark environment
12. The side adopts a portable pen clip design for easy carrying
13. Durable screwdriver bits, one-way/cross switch, high strength and wear resistance
14. The default AC voltage mode is turned on, the screen displays OV, the hand needs to touch the touch pole, and the screwdriver bit contacts the measured voltage. When a large voltage is measured, the screen turns red and a buzzer alarm sounds
15. NCV non-contact voltage detection, after switching to this mode, the screen displays EF. When the nearby AC voltage is detected, the screen rises from EF to ---. The closer to the power source, the more urgent the buzzer alarm
16. Press and hold for 3 seconds to turn on the flashlight, and the position of the measured object can be clearly viewed in a dimly lit environment
17. The meter automatically shuts down after about 3 minutes without any operation, saving energy and power
