1.
If the instrument detects a frequency higher than the
maximum limit (63Hz), it does not carry out the test and
displays a screen like the one to the side.

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.

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.

If the instrument detects a dangerous voltage on PE
conductor, it provides the warning screen shown to the
side and blocks the execution of the tests. Check the PE
conductor and earth connection efficiency.
