Automatic shutdown

When the test pen does not receive any operation within 5 minutes and does not detect the AC voltage, it automatically turns off.

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.
