9.6.2. PRESSURE CALIBRATION
A sensor at the sample chamber outlet continuously measures the pressure of the sample
gas. These data are used to compensate the final CO concentration calculation for
changes in atmospheric pressure and is stored in the CPU’s memory as the test function
PRES (also viewable via the front panel). See also Section 5.9.6.
IMPORTANT
IMPACT ON READINGS OR DATA
This calibration must be performed when the pressure of the sample gas
is equal to ambient atmospheric pressure. Before performing the
following pressure calibration procedure, disconnect the sample gas
pump and sample gas-line vent from the rear panel sample gas inlet.
