Selecting an item in the Logbook selection menu displays the corresponding history. History
entries are shown as list views. After a list view has been opened by pressing the ↵ key, the
cursor keys can be used to scroll vertically and horizontally through its content. Pressing the
ESC key closes a list view. Pressing the [Back] button returns to the selection menu.
Calibration history
This history saves the calibration process data for each input. Up to four entries can be stored
for each input, and older entries are overwritten, except for the first calibration.

Figure 4-16: Calibration history
When an input is selected, the appropriate calibration history is displayed in the corresponding
field, if the input has already been calibrated. The entry for a calibration process consists of
two rows, listing first the test gas measurement and then the zero gas measurement. The
first
calibration entry is designated by a “*” at the beginning of the zero gas measurement row.
If a separate zero adjustment has been carried out, the values for “Concentration” and
“Measurement value” are blanked in the Span Gas Measurement line by “———”.
Each entry includes the following data:
• Date/Time of accepting and closing the calibration menu
• Gas types for the zero and test gases
• Gas concentrations for the zero and test gases
• Measured values for the zero and test gases
• Difference signal Ux for the zero and test gases (scroll to the right)
Events (system error, signal problem and alarm history)
This history stores the system errors, signal problems, and alarms for the individual inputs.
Each entry includes the following data:
• Date/Time that the event occurred
