Time periods for average, minimum, maximum, and total values
For the current test, running average, minimum, maximum, and total values for each process variable
are calculated from the beginning of the test. When the well test is stopped, the final values will be
stored with the test data.

Other activity during a well test
Between well tests, you can use the Exit button to move between the Well Performance Measurement
menu and the View menu. While a well test is in progress, you can use the Exit button on the Return
to Well Test screen to move between the well test screens and the View menu.

to Well Test screen to move between the well test screens and the View menu.
From the View menu, you can perform any available actions.
At any point from the well test screens, including during a well test, you can press the Security button
to access the Configuration and Maintenance menus. The system does not prevent configuration
changes, calibrations, or other procedures. However, many actions (e.g., reconfiguring well data) will
cause discontinuities in the well test data, and many procedures will interfere with data collection. If

you need to change system configuration or perform a maintenance procedure:
1. Stop the well test.
2. Make the required configuration changes or perform the required procedures.
3. Start a new well test.
