Start Run screen key to start a run with a non-PowerLine autoinjector.
To begin a run with an autoinjector using the Start Run key:
1. Load the sample vials into the autoinjector.
2. Program and start the autoinjector. See the autoinjector documentation.
3. Press the Start Run key as soon as possible after the injection occurs. Note that the
Start Run key does not initiate an inject switch contact closure.
Starting the Run Time Clock
When the controller receives an Inject signal from an injector, the system status changes to
Running and the run time clock begins counting at 0.00. The system does not accept
another Inject signal until the run concludes or you abort the run.
Completing a Run
When a run completes, the system status changes from Running to Idle.
