Operation description:

Acousto-optic discrimination of Live or Null Wire:

- Live Wire Testing:
When the sensor end of the measuring pen is close to the object to be measured, the fast-paced buzzing alarm of the tester gives out an alarm sound, and the screen flashes red light, indicating that the test is a LIVE WIRE.

- Null Wire testing:
When the sensor end is close to the object to be measured, the slow-paced buzzer alarms, and the display screen flashes green light, indicating that the tested line is Null Wire.

* AC voltage detection
The voltage detector probe is placed near the AC voltage. When the voltage is induced, the signal light will be lit. The display of the screen will become higher or lower as the voltage signal intensity is induced, and the beep hint will become faster or slower with the signal intensity.
