Display Parameters
Use the Parameters menu to select which parameters to display on the data lines. When you
select parameters for display on any of the four data lines, those selections remain valid until
you change them again, even if you turn the 973 off. See Selecting Parameters to Display on
page 6 to select which values to display. A list of the available parameters follows. Note that
not all parameters are available on all systems since some systems may not contain the
associated hardware components.
Dew Point
Frost Point
%RH
%RH WMO
Volume Ratio
Weight Ratio
Absolute Humidity
Specific Humidity
Vapor Pressure
Head Pressure
Atmospheric Pressure
Flow Rate
External Temperature
Head Temperature
Graphing Data
Any value that you can view numerically can also be viewed as a graph at any time. The 973
automatically maintains a short history of each and every selectable parameter so that a graph
may be seen instantly whenever a data line is toggled from a numeric mode to a graph mode.
Selecting Between Numeric Data and Graph
Selecting between numeric and graph modes is done with the Numeric / Graphic menu. See
Selecting Graph vs. Numeric Data on page 7.
Changing Graph Attributes
To change the graph attributes, you need to
bring up the graph dialog. Do this by pressing
the touch screen directly on the graph whose
attributes you’d like to change.
