Fault messages
Any malfunctions detected are indicated by means of an error
message.
An error message is cleared from the display when you acknow-
ledge it. However, it will be displayed again if the cause of the
fault has not been eliminated.
If a number of faults are present at the same time, the next error

The exhaust-gas measuring instrument is only released again for
operation once all error messages have been displayed.
