PRESSURE CALIBRATION

122
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
changes in atmospheric pressure when the instrument's TPC feature is turned on (refer
to Section 5.8, Table 5-2) 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, SETUP>MORE>DIAG (refer to Figure 5-16), then press:

Adjust these values until the
displayed pressure equals the
pressure measured by the
independent pressure meter.
