Other Constants (continued)
Flow Span Enter the multiplication factor (flow rate/volt) used in conjunction with
Flow_Offset to convert voltage input from flowmeter into actual sample flow
rate. If the internal mass flowmeter is installed, the value is factory set and
should only be changed if the flowmeter is replaced.
Flow Offset Enter the additive factor (flow rate) used in conjunction with Flow_Span to
convert voltage input from flowmeter into actual cell temperature. If the
internal mass flowmeter is installed, the value is factory set and should only
be changed if the flowmeter is replaced.
Dry_CF This parameter, dry cell frequency, is the nominal cell frequency determined
during factory calibration of the instrument and is given for informational
purposes only.
Cell_SN Analyzer cell serial number. This value should only be changed if a new cell
is installed.
MoistGen_SN Moisture generator serial number. This value should only be changed if a
new moisture generator is installed.
Display (Display Flags)
This menu item is used to select the system values to be continuously displayed on the first three
