Read the safety precautions before beginning any procedures in this chapter.
WARNING If the equipment is operated in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
WARNING The Model 49i Primary Standard is supplied with a three-wire
grounding cord. Under no circumstances should this grounding system be
defeated.
Equipment Damage Some internal components can be damaged by small
amounts of static electricity. A properly grounded antistatic wrist strap must
be worn while handling any internal component. For more information
about appropriate safety precautions, see the "Servicing" chapter.
See the "Servicing" chapter for a list of replacement parts.
Clean the outside case using a damp cloth being careful not to damage the
labels on the case.
Equipment Damage Do Not use solvents or other cleaning products to
clean the outside case.
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.
CAUTION Some internal components can be damaged by small amounts of
static electricity. A properly grounded antistatic wrist strap must be worn
while handling any internal component. For more information about
appropriate safety precautions, see the "Servicing" chapter.
