EXAMPLES FOR FINDING, FIXING AND CHANGING CALCULATIONS
This section presents examples involved in finding, fixing and changing
calculations. In addressing the steps or procedures involved in accomplishing this,
the specific application example chosen to demonstrate this will be "Application
Number 51119110". In this application example, the MODEL 2500 has been
configured to measure the mass and volume flow rate of a process gas containing
a mixture of natural gas and carbon dioxide.
The MODEL 2500 computes a variable named CURSCF (current standard cubic
feet) based on analog input variables, and the following procedures find, fix, and
change the value of the calculated volume.
FINDING THE CALCULATION
The calculation for current volume appears as CURSCF on the display, and is
displayed, fixed, and changed in the CALCULATIONS menu, which is a sub-menu
of the MAIN MENU.
The CALCULATIONS sub-menu is accessed with the following procedure.
Begin with the following illustrated display screen, which shows the first
menu selection on the MAIN MENU, and indicates that the MAIN MENU
is active:
