This guide outlines the First Trip/Close Test using an external trigger only. - Page 101 Trigger event: • Close • Open The trigger event is the change of state the TDR9000 is expecting to see before recording the test data. During a First Trip Test, the closing of the 52CS/T contacts initiates the recording. During a First Close Test, the closing of the 52CS/C contacts initiates recording.
