6. 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 shuko plug or check the
connection of measuring cables.
7. If the instrument detects that the phase and PE leads
are inverted, it does not carry out the test and a screen
similar to the one reported to the side is displayed.
Check the connection of measuring cables.
8. If the differential switch being tested trips during the
preliminary checks (performed automatically by the
instrument before executing the selected test), the
instrument does not carry out the test and displays a
screen like the one to the side. Check that the IdN set
value is consistent with the differential switch in
question and that all loads connected downstream of it
are disconnected.
9. If the instrument detects a dangerious 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 plant efficiency. This message
can also appair in case of an insufficient pressure of the
GO/STOP key
10 If the instrument detects a dangerious contact voltage
Ut (over the set limit 25V or 50V) in the starting pre-
test, it provides the warning screen shown to the side
and blocks the execution of the tests. Check the PE
conductor and earth plant efficiency
