  9. If you want to accept the suggested name for the file click once with the left mouse button on the Save option box. You may replace the suggested name by hitting the space bar once to clear the line. Type in the new file name before saving the file. You may also change the location of where the file is saved on your PC by changing the location designated in the Save In box. You may save the file to your A drive for example. Once the file has been saved the process is complete.

  6. Start the replay of a snapshot by clicking on Play . The play button changes to Pause when a snapshot is replaying. While the snapshot is replaying, the replay slider next to the Play/Pause button moves showing the progress of the replay, and the time box next to it shows the time since the beginning of the recording. When you click on Play the snapshot begins to play from its current position and the instruments show the appropriate readings. The event window also changes during the replay to show the most recent event.
  7. Stop the replay at a particular point of interest by clicking on Pause . The instruments will show the values at the time the replay was stopped.
  8. Move to a specific time in the replay by dragging the replay slider button. As you drag the slider, the time shown in the time box changes to reflect the position of the slider.

    Note: Not all DDDL windows can be activated when replaying the snapshot feature. You cannot access the injector response time window or the cylinder cutout window in snapshot mode. Samples of windows that may be activated include:
