x | Model 933S UV Analyzer
If the analyzer uses the optional Measuring Cell heater, take precautions to avoid burning
yourself; the Measuring Cell and Heater Assembly are hot.
Cautions
Review and follow these Cautions to avoid damaging the equipment.
The electronic circuit boards and other static-sensitive components should be stored and trans-
ported in static-shielding carriers or packages.
For electrical-shock protection, the analyzer must be operated from a grounded power source
that has a securely connected protective-ground contact.
If it becomes necessary to handle any of the electronic circuit boards, do not subject the boards
to static discharge. The ideal solution is a static-safe work area. Since such areas typically are
not available at field installation sites, the use of a wrist strap connected directly to a ground
is recommended. If a wrist strap is not available, you should at the very least touch the metal
chassis (to ground yourself) before handling or touching the boards.
When handling the source lamps, it is very important not to touch the lamp windows because
residual oils from the fingers will absorb ultraviolet light. The window is the flat surface at the
end of the narrow glass tube. The lamp assembly is fragile and should be handled with care.
Do not exceed the maximum working pressure rating of the sample system under any circum-
stances:
• Systems with Filterblock Assembly: 13 790 KPAG (2000 PSIG).
• Systems without Filterblock Assembly: 20 700 KPAG (3000 PSIG).
If the analyzer is equipped with the Environmental Purge option, clean air or nitrogen can be
supplied to the inlet flame arrester at a pressure of 7–70 KPAG (1–10 PSIG).
