11. Completion Status Automatically Initiated Manually Initiated Aborted Because The Test Train Was Off-Line Aborted Because The Test Line/ Configuration-Valve Was Off-Line Aborted Because The Well/ Control-Valve Was Off-Line Cannot Read Temperature Meter Stopped By Operator Aborted By Operator Aborted Due To Priority Leak Test Aborted Due To High Fluid Level In Separator Aborted Due To Valve Error Aborted Due To Low Flow Rate Aborted Due To Test Train Pump Shut Off Failure Even The Fluid Is Below LSL Aborted Due To Emergency Automation Shutdown Aborted Due To Ac Power For Field Devices Failure Aborted Due To Ac Power For Controller Voltage Failure Aborted Due To Error Reading Instruments Aborted Because The Wtc Was Unable To Purge The Separator Aborted Due To High Production Aborted Due To No Flow Into Separator Normally Completed Aborted Due To Bpcv Fail 0 = No 1 = Yes
