3.1 Power supply
The device is powered from the network 187 V ... 265 V, 50 Hz.
Two 15 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).
500 mA fuse protects 200 mA current controller for R

measurement.
3.2 Start test after switching the meter on
After switching on, the meter performs self-test to check its correct operational condition and
when this test is successfully completed, the meter automatically performs the following measure-
ments:
measurement of the voltage in the power supply socket, i.e. the voltage between L and N of
power supply to the meter
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
When everything is correct the following screen is displayed:
