ENV-520 Test...
This menu option provides a graphical interface for testing the ENV-520
controller, photo beam strips, and the interrupt on the DIG-729 card for each
chamber (Figure 3-8) and for all chambers simultaneously (Figure 3-9). This can
also be used to test if the Video Tracking Interface (VTI) system is working
properly. To test the VTI system, please be sure that the Preferences menu is set
to Use Video Tracking, and that the appropriate computer is selected. Then
start capturing data on the VTI system. Once this is done the ENV-520 Test can
be run. This ensures that the equipment is in proper working order and identifies
where hardware problems may be occurring. Should there be problems with the
system, contact MED Associates for troubleshooting help.
This test should be run when the equipment is set up, and if using the DIG-729,
before every session. First run the multi-chamber test by checking the Display
Raw Values check box. Make sure that there are no subjects in the chambers.
Click start. If the X, Y, or Z values are any number other than zero, check for
obstructed photo beams. The number of beam breaks should be zero. If there
are multiple beam breaks on the X, Y, or Z-axis when no subjects are in the
chamber please contact MED Associates. If there are many chambers (nodes)
with values other than zero, contact MED Associates.
