SIGNAL CONVERT: It can detect a rf signal of power from -74dBm to 18dBm, and convert the RF signal into a DC voltage output.
NOTE: The higher radio frequency signal range or power is, the higher output voltage will be; output voltage is proportional to logarithm of input signal range.
[User friendly operation] - Easy to use. Just press the button to turn it on and hold the tip close to the electrical source for immediate voltage detection. No complicated procedures or technical know-how required.
[Multi functional] - Features a built-in flashlight to aid you in working in dark environments. The detection light flashes red and the buzzer emits a brief beep when AC voltage is detected.
MULTI FUNCTIONAL: Features a built in flashlight to aid you in working in dark environments. Whenever the voltage tester detects AC voltage, the detection light flashes red and the buzzer emits a brief beep.
SAFE AND PRACTICAL: This non contact AC voltage detector only requires you to place the tip near the wiring board, socket, or power line. When the tip emits a red light and the pen beeps, you will know the presence of voltage. Professionally designed and manufactured, it ensures safety and reliability.
Fast Charging: Controller battery pack has a 1500mAh battery with 560MA charging current, adding up to 10 hours of active play time to the controller, and it only takes 3 hours to fully charge the battery.
Indicator Light: Battery pack with LED indicator light. The remaining battery capacity indicator will stay on while charging, and the four battery indicators will stay on when fully charged.
