10. INSTRUMENT MAINTENANCE
Predictive diagnostic functions including data acquisition, failure warnings and alarms built into the analyzer
allow the user to determine when repairs are necessary without performing unnecessary, preventative
maintenance procedures. There is, 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. Maintenance,
repair and troubleshooting procedures are covered in Chapters 10 and 11 of this manual.
NOTE
A span and zero calibration check must be performed following some of the maintenance procedures
listed below. Refer to Chapter 8.
CAUTION
TRICAL SHOCK. DISCONNECT POWER BEFORE PERFORMING ANY OPERATIONS
THAT REQUIRE ENTRY INTO THE INTERIOR OF THE ANALYZER.
NOTE
THE OPERATIONS OUTLINED IN THIS CHAPTER MUST BE PERFORMED BY
QUALIFIED MAINTENANCE PERSONNEL ONLY.
NOTE
The front panel of the analyzer is hinged at the bottom and may be opened to gain access to various
components mounted on the panel itself or located near the front of the instrument (such as the
particulate filter).
Two fasteners located in the upper right and left corners of the panel lock it shut (refer to Figure 3-1).
