5 Menu and function overview
The following section describes the functions of all user menus that are available for adjusting the analyzer system to the conditions
of the biogas plant.
The individual user menus can be accessed in setup mode. The setup mode, for its part, is accessed via the key switch.

Not every interval is permitted. The interval must be a divisor of 1440, i.e. the number of minutes of a day. If the value
entered does not fulfill this requirement, the SSM 6000 automatically uses the nearest setting. However, the measuring
interval should not be set at a value of less than 120 minutes. This corresponds to 12 measurements a day.
If the device is controlled via the digital inputs or via the Profibus interface, an H

The different menu items can now be selected via the membrane keypad.
For further details concerning operation, please refer to the "Using the gas analyzer" section.
- Setting the measuring interval for every component to be measured.
- Setting the limit-value concentrations for the different gas types.
- Performing one manual measurement.

irrelevant because these other gas components are measured continuously.
In automatic measuring mode, the reference time determines the time when the first measuring
process starts. After this measuring process, the next measuring process is then started xxx minutes
later, depending on the set measuring interval.
The "offset" selection (_OFS: 0000) enables the automatic starting of measuring processes in the
intervals defined for the day with the "minutes" entry edited to this effect.
