13 MAINTENANCE
The calibrator 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.
13.1 Error
messages
MicroCal 20
performs the auto-diagnostic procedure when switched on. When measuring it checks also for anomalous conditions. If the calibrator founds trouble, it displays a
message on LCD. Sometimes, these messages correspond to an unrecoverable problem and it is necessary to return the instrument to Eurotron for maintenance. Frequently these
messages are referred to a recoverable trouble and can be solved by you.
