Resistance L – N too
high (>30 kΩ).
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.
Resistance L – N too
low.
Are you sure to
proceed? (Y/N)
An extremely low resistance of the appliance’ supply input
was measured in the pre-test. It is likely that fuses will
blow after applying power to the tested appliance. If the
too high current is only of short duration (caused by a
short inrush current) the test can be performed otherwise it
must be stopped.
Select YES or NO with Y or N key.
It is recommended to additionally check the appliance
before proceeding with the test!
Leakage LN-PE high.
Are you sure to
proceed? (Y/N)
Dangerous leakage current (higher than 3.5 mA) will flow if
power would be connected to the tested appliance.
Select YES or NO with Y or N key.
Proceed with testing only if all safety measures have
been taken. It is recommended to perform a thorough
earth bond test on the PE of the appliance before
proceeding with the test.
Leakage LN-PE too
high.
Are you sure to
proceed? (Y/N)
Dangerous leakage current (higher than 20 mA) will flow if
power would be connected to the tested appliance.
Select YES or NO with Y or N key.
Proceed with testing only if all safety measures have
been taken. It is recommended to perform a thorough
earth bond test on the PE of the appliance before
proceeding with the test.
