3.2 Automatic Recognition of Mains Connection Errors
The test instrument automatically recognizes mains connection errors,
if the conditions in the following table have been fulfilled. The user is
informed of the type of error, and all measuring functions are disabled
in the event of danger.
1)
In SETUP – test sequence – IT system
Attention!
!
If you discover during the protective conductor potential test
that the mains protective conductor is charged with voltage (in ac-
cordance with the two cases mentioned first), you may no longer
perform any measurements with your test instrument. Voltage is ac-
tually present at the exposed earthing contacts of the standard
socket (21) as well and may be dangerous to you. Disconnect
the test instrument from the mains immediately and see to it that
the defect at the mains connection is repaired.
Note
+
Voltage at the electrical system’s protective conductor PE may result in
distorted measurement values during testing for the absence of
voltage, or during leakage voltage measurements.
4 General Notes
4.1 Online Instructions
Integrated online instructions inform the operator regarding all required
connections, necessary work steps, operator errors, measurement results
and more in all measuring modes.
Information and test results appear at the dot matrix LCD in clear text.
4.1.1 Changing the User Interface Language
If you require a different language for the user interface of the test instru-
ment, you can load it into your test instrument by means of the update
and options installation program „SECU-Up“. The program is available for
download from our website www.gossenmetrawatt.com (Products >
Software > Software for Testers > SECU-Up).
Upon installation on your PC and starting the program, you proceed by
selecting the „Update“ menu and choosing a language from the following
list:
Deutsch, English, Français, Italiano, … .
Only one language at a time can be installed on the test instrument, the
one previously installed is overwritten in the process.
Attention!
!
During data transmission, the test instrument and PC may not
be disconnected from the mains power supply under any cir-
cumstances.
No other programs under WINDOWS may be activated during
the update.
