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.

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.
