1. AC voltage range: non-contact measurement 30~1000V; contact measurement 11V~450V
2. Frequency: 50~60Hz
3. Alarm mode: screen backlight color change + buzzer alarm
4. Identify neutral and live wires: the live wire is the one with a large electric field strength or a high voltage value
5. Induction intensity indication: three-grid scale indication "—" weak electric field; "— —" medium electric field; "— — —" strong electric field
6. Safety level: CE CAT.II 1000V/CATIV 600V
7. The backlight is turned on when the machine is turned on, and the screen value can be clearly seen in a dark environment, and it is still clear in backlight
8. Open the battery cover to replace the 1.5V No. 7 battery (not included)
9. Finger touches the touch key to measure. When the induction electric field is weak, the screen backlight is green, and when the induction electric field is 10. When the field is strong, the screen is backlit in red and emits a buzzer alarm
11. Press and hold the touch key to measure the AC voltage. Insert the tip of the test pen into the socket and the screen turns red when high voltage is detected
12. Made of insulating material, it is safe and reliable to measure electricity, shatterproof and durable, effectively protecting the hardware inside the test pen circuit board from damage
13. 4mm bit diameter, 24mm length, it is both an electric pen and a screwdriver with high torque and durability, and stable contact performance
14. The meter automatically shuts down after about 3 minutes without any operation
15. Size: 17x3.35 cm
