4.3 Calibrations - One Point Dynamic Test
The One Point Dynamic Test test the accuracy of the stopping position after a gantry move. A
command is given to move the camera away from the target, then return to the target and the
variation between the theoretical and actual stop position as measured by the camera is analysed.
The process is repeated 50 times.
Step 1
1. Remove the cover (1) by loosing the 4 screws.
2. Check the glass target (2) for scratches or damage. Clean with lint free cloth & IPA if
necessary.
