1. If no buttons are pressed or operations are detected for an extended period, the device will automatically shut down after approximately 3 minutes to prevent unnecessary battery drain and extend battery life 2. The probe tip features a built-in LED light, providing additional illumination for maintenance work in dimly lit electrical panels, cable trays, and suspended ceilings 3. Equipped with a dual-purpose flathead and Phillips screwdriver bit, it combines voltage testing with basic screw removal and installation functions 4. The battery compartment features a snap-on rear cover, making battery replacement simple; if the battery runs out during outdoor work, you can quickly replace it to resume operation 5. Equipped with a high-precision smart recognition chip for sensitive detection and stable signals 6. NCV (Non-Contact Voltage) graded visual indicators: red indicates a strong electric field, dark green indicates a medium electric field, and light green indicates a weak electric field, allowing you to determine whether a circuit is live from a distance 7. Metal clip on the side of the pen body for easy carrying in workwear pockets 8. Insulated, non-slip housing ensures safer use during high-voltage testing
Parameters 1. Voltage range for measurement: non-contact: 30 - 1000V; Contact: 11V - 450V 2. Frequency: 50 - 60Hz 3. Alarm method: screen backlight color change + sound 4. Identification of live and neutral wires: the wire with higher electric field intensity or higher voltage value is the live wire 5. On-off beeping: when the wire is connected: the screen displays 0 and the buzzer emits sound 6. Battery low voltage: when in use, the screen displays LO indicating insufficient battery power and a battery replacement is required 7. Operating temperature: 0 - 40 degrees Celsius 8. Storage temperature: 10 - 50 degrees Celsius 9. Altitude: less than 2000m 10. Automatic shutdown: automatically shuts down after no operation for 3 minutes 11. Power supply: 1.5V AAA x 2 (battery not included in shipment) 12. Flashlight: white LED light 13. Material: ABS
