These safety pre-tests check for: • • • • • any external voltage against earth on test socket, excessively high leakage current, excessively high touch leakage current, Short circuit or too low resistance between L and N on appliance, Correctly applied mains voltage to the test socket.
OmegaGTPlus / BetaGTPlus Resistance L – N too high (>30 kΩ). Check fuse and switch. Are you sure to proceed? (Y/N) Resistance L – N low. Are you sure to proceed? (Y/N) Resistance L – N too low. Are you sure to proceed? (Y/N) Leakage LN-PE high. Are you sure to proceed? (Y/N) Leakage LN-PE too high. Are you sure to proceed? (Y/N) Instrument description An excessively high resistance was measured in the fuse pre-test.
OmegaGTPlus / BetaGTPlus Leakage LN-PE or EBPE too high! Are you sure to proceed? (Y/N) Instrument description 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.

OmegaGTPlus / BetaGTPlus Appendix B Appendix B The instrument OmegaGTPlus / BetaGTPlus supports two barcode formats when printing appliance labels. Autotest shortcut code and appliance number Autotest shortcut codes are represented as a two digit code. These autotest codes can also be represented by the barcode. Using the barcode reader, the instruments can accept autotest shortcut code from barcode label. 01 Autotest shortcut code Also appliance number can be read from barcode label.
OmegaGTPlus / BetaGTPlus 01 $ 4455821981 Appendix B Autotest shortcut code Separator Appliance number Refer to chapter 3.9.6 Instrument settings for barcode system selection. Notes: Ì Special character »$« between autotest shortcut code and appliance name (ID number) is used to distinguish shortcut code from appliance name. Ì Only appliance ID is printed out on the 2nd appliance label (power supply cord label).
