5.9.7. PRESSURE CALIBRATION
A sensor at the exit of the sample chamber continuously measures the pressure of the
sample gas. This data is used to compensate the final SO
sample gas. This data is used to compensate the final SO

concentration calculation for
changes in atmospheric pressure when the instrument’s TPC feature is turned on (refer
to Section 10.7.3) and is stored in the CPU’s memory as the test function PRES (also
viewable via the front panel).

Ensure to use a barometer that measures actual barometric pressure.
To cause the analyzer to measure and record a value for PRES, access the Signal I/O
from the DIAG Menu (refer to Figure 5-16), then press:
