L and N are crossed.
Press START key to
continue.
The instrument works normally also in the case when L
and N are interchanged. Check polarity of line and neutral
wires on test socket.
Warning!
Mains voltage is not correct
or PE not connected or 110 V
centre tapped / IT system.
Press START key to continue
if 110 V centre tapped / IT
system.

Ì
no earth connection or other wiring problem on
supply socket,
Ì

Resistance L – N too
high (>30 k
Ω
).
Check fuse and switch.
Are you sure to
proceed? (Y/N)
An excessively high resistance was measured in the fuse
pre-test. Indication means that appliance has too low
consumption or is:
Ì
not
connected,
Ì
switched
off,
Ì
contains a fuse that has blown.
Select
YES
or
NO
with Y or N key.
Resistance L – N low.
Are you sure to
proceed? (Y/N)
A low resistance of the appliance’ supply input was
measured in the pre-test. This means that it is very likely
that an excessively high current will flow after applying
power to the tested appliance. If the high current is only of
short duration (caused by a short inrush current) the test
can be performed, otherwise not.
Select
YES
or
NO
with Y or N key.
