10. MAINTENANCE
Warning
All replacement parts must be as supplied and/or specified by California Analytical
Instruments. Failure to used specified parts may reduce the safety features of the
instrument or create a hazardous condition.
10.1. Zero and Span Calibration
The zero and span levels should be checked and/or calibrated daily (or as often as required.)
10.2. Cleaning of the Optical Bench Measuring Cell (Infrared Analyzers Only)
Dust or water droplets entering the measuring cell may cause drift due to contamination.
When it is impossible to adjust the zero level with the zero control mounted on the front panel,
check the measuring cell for contamination. If contamination is present, check the sampling
system, especially the filters, to eliminate the source of contamination. Periodic maintenance
is generally not required. Cleaning is accomplished by use of a cleaning agent (such as
isopropyl alcohol or household glass cleaner) and a non-abrasive, lint-free cloth or tissue.
10.3. Optical Bench Configuration
Infrared analyzers may be configured with three types of optical benches: with a pipe cell; with
a block cell; or with both a pipe cell and a block cell (see Table 10-1))
