Contrast
The contrast of the display can be changed. The changes of the contrast are imme-
diately visible. The recommended value under regular conditions is 50 (or close to it).
If the display setting is too light or too dark, so that the menu items cannot be read,
the contrast can be reset to the default setting as follows:
1 Shut off the Modul1000 and restart it again.
2
During the run-up phase, press the key No. 3 or 7 until the display is clearly readable.
This setting is only saved permanently after confirmation in the Contrast menu. If this
setting is not confirmed, the former setting will be used for the next start of the
Modul1000.
Background in Standby
In Standby mode, the internal helium background can be displayed.
Lower display limit
This parameter defines the lower leak rate limit in the measurement ranges. This is
valid for vacuum modes only. The lower display limit applies for the graphical
diagram of the leak rate and for the numeric output of the leak rate as well. The
Modul1000 does not display leak rates below the lower display limit.
The lower display limit can be selected between 1x10

the measured leak rate exceeds the set trigger threshold, the Modul1000 reacts as
follows:
Display: At the bottom of the display, the symbols for the trigger 1,2, or 3 are
displayed in inverted colours.
Relay output: The trigger relay of the PLC-outputs switches over.
Alarm/Loudspeaker: If the trigger threshold 1 is exceeded, an audible alarm signal is
generated by the loudspeaker of the Modul1000.
