Rosemount Analytical P/N
3530B07G01 for probe 0.4%
oxygen in nitrogen in dispos-
able bottle.
Rosemount Analytical P/N
3530B07G02 for probe 8%
oxygen in nitrogen in dispos-
able bottle.
3 A check valve is required at
the probe (between the cali-
bration fitting and the gas line)
to prevent the migration of
process gases down the cali-
bration gas line.
(b) Calibration with a Portable Rose-
mount Analytical Oxygen Calibra-
tion Gases Kit.
1 A typical portable calibration
setup is shown in Figure 4-3.
For manual (semiautomatic)
calibration, remove cap plug
from the calibrate in place fit-
ting. The cap plug must be
retained to seal this fitting af-
ter calibration is complete;
failure to do so may render
the probe useless if the sys-
tem pressure is slightly nega-
tive. The reference air should
be flowing as in normal
operation.
2 Refer to paragraph 4-2.d of
this section for Manual (Semi-
automatic) Calibration setup
and procedure using the IFT.
3 Screw the pushbutton regu-
lator with contents gage on to
the calibration gas of choice
and inject the calibration gas
by opening the valve. Gas is
on continuously when the
valve is opened.
