e. Handling the Analyzer
The probe was specially packaged to pre-
vent breakage due to handling. Do not re-
move the padding material from the probe
until immediately before installation.
It is important that printed circuit
boards and integrated circuits are
handled only when adequate antistatic
precautions have been taken to pre-
vent possible equipment damage.
The oxygen probe is designed for in-
dustrial applications. Treat with care to
avoid physical damage. The probe
contains components made from ce-
ramic, which are susceptible to shock
when mishandled. THE WARRANTY
DOES NOT COVER DAMAGE FROM
MISHANDLING.
f. System Considerations
Prior to installing your Rosemount Two-Wire
In Situ Oxygen Analyzer, make sure you
have all the components necessary to make
the system installation. Ensure all the com-
ponents are properly integrated to make the
system functional.
After verifying that you have all the compo-
nents, select mounting locations and deter-
mine how each component will be placed in
terms of available line voltage, ambient
temperatures, environmental considera-
tions, convenience, and serviceability. Fig-
ure 1-2 shows a typical system wiring. A
typical system installation is illustrated in
Figure 1-3.
