Measuring Process

After switching on, the voltage tester is in high-voltage mode. The high-voltage mode LED  lights up white.

  1. To switch the voltage range to low-voltage mode, press the  button. The low-voltage mode LED  will then light up white. The voltage tester is ready for detecting AC voltages in the range of 24 to 1000 V AC.
In the low-voltage mode , the voltage tester is more sensitive to electrical interference and faults. Only use the low-voltage mode in environments with weak electrical fields.
  1. Hold the probe tip (1) near the test object or the plug socket with AC voltage.

An audio signal will sound and the voltage tester will vibrate when it detects an AC voltage. The frequency of the audio signal and the vibration increases the stronger the detected voltage is.

The probe tip (1) indicates different states of the voltage tester according to the table below.

Probe tip

Meaning

Continuous green light

Ready for operation, no voltage is detected.

Flashing red light

AC voltage detected.

Flashing orange light

AC voltage lower than or equal to 50 V detected.
