4. Measurements
4.1. Presentation of results
4.1.1. PASS / PASS * / FAIL result
Depending on the limit set in the selected test, the result is marked either with a PASS
or FAIL message. Limits are shown in the upper right corner of the display.
The message is always displayed as well as the actual measured result (except in
visual test).
A conditional PASS (PASS*) message is shown if one or more tests in the set Autotest
routine are skipped or aborted. In this case all performed tests must PASS. Otherwise,
FAIL is shown.
4.2. Manipulation
After start–up of the instrument, the MAIN MENU is displayed:
Fig. 4.1 Main menu
To select an option from the menu, use UP and DOWN keys. The selected option will
be highlighted. The selection is confirmed with the ENTER key. To return into MAIN
MENU from any sub-menu, press the ESC key.
4.2.1. Help option
In all measurements a help menu is available with connection diagram and instructions
on how to perform the test. Where there are two options (Class I or Class II appliance),
descriptions for both are available. The last page (or two) of the help menu provides
guidance on why a test may fail (e.g. connection problems). An example help menu for
earth bond measurement is presented in the following figures.
