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
plug or check the connection
of the single cables

7. If the instrument detects a
phase-to-neutral voltage and
a phase-to-earth voltage
lower than the limit, the
message reported here to
the side is displayed. Check
that the system being tested
is energized
