3 Switching on and main menu
3.1 Power supply
The device is powered from
mains 195
…265 V, 50 Hz.
Two 16 A fuses protect L and N
lines from the supply socket to the
test socket. They are tripped when
current consumption from the test
socket is too high (>16 A).
3.2 Start test after switching the tester on
After switching on, the tester performs a self-test to check its correct operational condition. When
this test is successfully completed, the tester automatically performs the following measurements:

voltage between L and N of power supply,

measurement of mains frequency,

checking the continuity PE in the power supply socket,

measuring the voltage between N and PE in the power supply socket,

indicates swapped L and N terminals
Upon completing above mentioned measurements, main menu screen is displayed. On the right up-
per corner of the screen mains network monitor is presented. It shows polarity of the power supply,
voltage between N and PE, voltage between L and N, as well as mains frequency.
For mains voltages below 195 V and above 256 V all test functions are automatically
blocked.
