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 H
changes in atmospheric pressure when the instrument's TPC feature (see Section 10.7.3)
is turned on and is stored in the CPU's memory as the test function PRES (also viewable
via the front panel).
To cause the analyzer to measure and record a value for PRES, press:
H2S =XXX.X
