10 MAINTENANCE
The EGA4 analyzer has been developed and manufactured using high quality components. A correct, systematic
maintenance will prevent damage and will increase substantially the life of the instrument, giving excellent results.
Anomalous conditions that require extraordinary maintenance interventions are promptly displayed, either clearly or with
an information code.
10.1 Error messages
The instrument performs the autodiagnostic procedure when switched on. When measuring it checks also for
anomalous conditions. If analyzer founds trouble, it display a message on LCD. Sometime these messages corresponds
to a unrecoverable problem and it is necessary to return the instrument to Eclipse for maintenance. Frequently these
message are referred to a recoverable trouble and can be solved by yourself.
The following table show the possible instrument error messages:
