3. If the measured phase-to-
earth insulation value is
lower than the set limit, the
instrument displays a screen
similar to the one reported
here to the side and gives a
long acoustic signal

5. If the instrument detects that
the phase and neutral leads
are inverted, the message
reported here to the side is
displayed. Rotate the shuko
