6.1.1. Anomalous situations
1. If the instrument detects a L-N or L-PE voltage higher
than the maximum limit (265V), it does not carry out the
test and displays a screen like the one to the side. Check
the connection of measuring cables.

2. If the instrument detects a L-N or L-PE voltage lower than
the minimum limit (100V), it does not carry out the test
and displays a screen like the one to the side. Check that
the system being tested is supplied.

3. If the instrument detects that the phase and neutral leads
are inverted, it does not carry out the test and a screen
similar to the one reported to the side is displayed. Rotate
the mains plug or check the connection of the measuring
cables.

conductor, it does not carry out the test and displays a
screen like the one to the side.
