OPERATION
3-1 OVERVIEW
This section specifies the requirements to set up
an Oxymitter 4000 calibration and how to verify
the calibration gas flow setup. It also explains
the differences between automatic and semi-
automatic calibrations and how to initiate them.
3-2 CALIBRATION
REQUIREMENTS
a.
Two tanks of precision calibration gas mix-
tures are required. Recommended calibra-
tion gases are nominally 0.4% and 8.0%
oxygen in nitrogen.
Do not use 100% nitrogen as a low gas
(zero gas). It is suggested that gas for
the low (zero) be between 0.4% and
2.0% O2. Do not use gases with hy-
drocarbon concentrations of more
than 40 parts per million. Failure to
use proper gases will result in errone-
ous readings.
In addition to the optional disposable gas
bottles available from Rosemount, two ad-
ditional sources of calibrated gas mixtures
are:

b.
A check valve is required at the Oxymitter
4000 (between the calibration fitting and the
gas line) to prevent the migration of process
gases down the calibration gas line.
A typical calibration setup for the Oxymitter
4000 is shown in Figure 1-4.
