affects current measurement and data collection. To change modes, follow the instructions in this
section.
To change from Well Test mode to Continuous mode:
1. If a well test is running, it will be stopped automatically when the mode is changed.
2. Perform all required or desired recalculations.
3. Well test data will be unavailable from the display while the system is in Continuous mode.
Record all required or desired well test data to an external system.
4. Change
Mode of Operation
to
Continuous Mode
.
To change from Continuous mode to Well Test mode:
1. If desired, save an archive record.
2. Perform all required or desired recalculations.
3. Continuous mode data will be unavailable from the display while the system is in Well Test
mode. Record all required or desired data to an external system.
4. Change
Mode of Operation
to
Well Test Mode
