Safety Precautions
Read the safety precautions before beginning any procedures in this chapter.
Replacement Parts
See the “Servicing” chapter for a list of replacement parts.
Outside Case
Cleaning
Clean the outside case using a damp cloth being careful not to damage the
labels on the case.
Optical Bench
Cleaning
Best results are obtained when the optical bench is cleaned prior to
recalibration. The cleanliness of the bench should also be checked any time
the detector frequencies drop below 65 kHz, since one source of low output
is light attenuation due to dirt in the cell. Dirt particulates are usually
effective ozone removers.
Use the following procedure to clean the optical bench.
WARNING If the equipment is operated in a manner not specified by the
