Model 360E Instruction Manual MAINTENANCE SCHEDULE & PROCEDURES
9. MAINTENANCE SCHEDULE & PROCEDURES
Predictive diagnostic functions, including data acquisition records, failure warnings and test functions built into the
analyzer, allow the user to determine when repairs are necessary without performing painstaking preventative
maintenance procedures. There are, however, a minimal number of simple procedures that when performed
regularly will ensure that the analyzer continues to operate accurately and reliably over its lifetime. Repairs and
troubleshooting are covered in Chapter 11 of this manual.
