Sys Admin
Test Calc
The test calculations screen provides a method to view the Model
3095FT flow, compressibility factor, and discharge coefficient
calculations for the current process variables. Optionally, the system
administrator can enter process variable values, and then view the
resulting calculations.
NOTE
Since Test Calc changes flow calculations and subsequent logged data,
the following procedure should only be performed during bench
configuration.
1. Select Sys Admin, Test Calc to display the Test Calculation
screen. The initial values indicate current process variable
readings.
2. (Optional) Enter values and units for DP, SP, and PT process
variables.
3. Click the Calculate button.
The test calculation screen updates continuously with flow,
compressibility factor, and discharge coefficient calculations. Wait
at least 30 seconds to allow for completion of the compressibility
factor and discharge coefficient calculations.
4. Select Exit.
The User Interface automatically switches the connected Model
3095FT to On-line normal operation.
