Strategy for Servicing
Throughout this manual, the term “module” refers to any field-replaceable
component, assembly, or part of the analyzer.
This manual contains all the information needed for periodic maintenance of the
analyzer. (Examples of such information are procedures for checking perfor-
mance.)
Further, it contains all information for corrective maintenance down to the
module level. To isolate a failure to a module, use the fault isolation procedures
found in Troubleshooting , part of section 6, Maintenance . To remove and replace
any failed module, follow the instructions in Removal and Installation Proce-
dures , also part of section 6. After isolating a faulty module, replace it with a
fully-tested module obtained from the factory. Section 10, Mechanical Parts
List,
contains part number and ordering information for all replaceable modules.
