The "is" lines show the current value of
the power supplies. The "was" values
show the values when the analyzer was
manufactured. Changes of more than a
few percent should be tracked. The 24V
power supply may differ substantially if
the Rosemount Analytical power supply is
not used. Use the MORE (3) softkey to
see additional values.

Shows the value of internal parameters
used in the primary variable calculation.
Barometric pressure compensation may
be enabled if another analyzer has a
pressure measurement device and is set
to report its reading.

Physical measurement...
Refer to Figure 3-14, page 3-13. These
are measurements made by the analyzer
module to verify proper functioning and
appropriate flows of sample and support
gases, if any. See Section 3-7i, page 3-
18 for a complete description.
