2.4. Meaning of symbols and messages on the instrument
display
Before performing a measurement, the instrument performs a series of pre-tests to ensure
safety and to prevent any damage. These safety pre-tests are checking for any external
voltage and load condition on test terminals. If a pre-test fails, an appropriate warning
message will be displayed. Warnings and protective measures are described in this
chapter.
WARNING!
Improper supply voltage warning. Possible causes:
 no earth connection or other wiring problem on
supply socket,
 instrument is connected to 110 V or IT earthing
supply system.
WARNING!
No voltage was detected on the mains input. Check mains
connection.
WARNING!
A low resistance of the appliance’ supply input was
measured in the pre-test. This means that most likely a
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 PROCEED or CANCEL.
WARNING!
A very 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 an inrush
current) the test can be performed otherwise it must be
stopped.
Select PROCEED or CANCEL. It is recommended to
additionally check the appliance before proceeding
with the test!
WARNING!
A high leakage current (higher than 3.5 mA) will flow if
power would be connected to the tested appliance.
Select PROCEED or CANCEL. Proceed with testing
only if all safety measures have been taken.
WARNING!
A dangerous leakage current (higher than 20 mA) will flow
if power would be connected to the tested appliance. The
instrument blocks the test.
