This section contains some procedures that may need to be performed when a major
component of the analyzer requires repair or replacement.
Note
Regular maintenance procedures are discussed in Section 5.5
and are not listed here). Also, there may be more detailed service
notes for some of the below procedures. Contact Teledyne API's
WARNING – ELECTRICAL SHOCK HAZARD
Unless the procedure being performed requires the instrument
to be operating, turn it off and disconnect power before
opening the analyzer and removing, adjusting or repairing any
of its components or subsystems.
CAUTION – QUALIFIED TECHNICIAN
The operations outlined in this chapter are to be performed
by qualified maintenance personnel only.
DISK-ON-MODULE REPLACEMENT PROCEDURE
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Servicing of circuit components requires electrostatic discharge
protection, i.e. ESD grounding straps, mats and containers.
Failure to use ESD protection when working with electronic
assemblies will void the instrument warranty. For information on
preventing ESD damage, refer to the manual, Fundamentals of
ESD, PN 04786, which can be downloaded from our website at
Manuals in the Special Manuals section.
Replacing the Disk-on-Module (DOM) will cause loss of all DAS data; it may also cause
loss of some instrument configuration parameters unless the replacement DOM carries the
exact same firmware version. Whenever changing the version of installed software, the
memory must be reset. Failure to ensure that memory is reset can cause the analyzer to
malfunction, and invalidate measurements. After the memory is reset, the A/D converter
must be re-calibrated, and all information collected in Step 1 below must be re-entered
before the instrument will function correctly. Also, zero and span calibration should be
performed.
1. Document all analyzer parameters that may have been changed, such as range, auto-cal,
analog output, serial port and other settings before replacing the DOM.
