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
