Viewing well test data
You can access well test data at several points in the menu.
Note: You can also read well test data via Modbus or report actual and average process variables by
assigning them to a milliamp or frequency output.
assigning them to a milliamp or frequency output.
To access basic data for the current well test, press View from the On Test screen (see Figure 5-2).
The values listed in Table 5-2 are displayed.
The values listed in Table 5-2 are displayed.
To access more detailed data for either the current test or a stored test, use the View Production
