Maintenance Procedures
4-3
Interchangeability
The Main and Input boards must be kept together because of the calibration data that is
stored in the main board EEPROM. In the case of one board being faulty, both must be
replaced.
Returning Materials
Should it become necessary to return the transmitter to
SMAR
, simply contact your local
agent or
SMAR
office, informing the defective instrument’s serial number, and return it to
our factory.
In order to expedite analysis and solution of the problem, the defective item should be
returned with a description of the failure observed, with as many details as possible.
Other information concerning the instruments operation, such as service and process
conditions, are also helpful.
