 Should the instrument detect a voltage
between phase and neutral higher of
265V, for example in case the blue
cable is connected to an installation

Message
"no VOL tAG”: a
too low voltage
was detected.
The instrument does not effect the test.
Reverse the shuko plug and exchange the black
cable with the blue one. Check the earth
connection. Repeat the test.
The instrument does not effect the test.
Reverse the phase to earth connection in the plug
under test or exchange the black cable with the
green one. Repeat the test.
The instrument does not effect the test.
Message “Att”:
too low voltage

and earth.
Message “Att”:
