In the normal case, only one of the first 3 LEDs is lit. If no LED is lit, there is a problem with the

6.7 Diagnostic Functions
The structure and operation of the “Diagnosis” menu are described in detail in the Instruction Man-
ual. In the following, some of the more important functions are described in greater detail.
The “Diagnosis” menu is divided into the submenus “Logbook” and “Measuring Data”.
In the “Logbook” menu, a series of failures and incidents is stored and can thus be used to conduct
an incident verification procedure at a later time.
The current status of the system, however, can be reviewed in the “Measuring Data” menu.
