Single Point Articulation Test (SPAT)
Mounting should always be tested prior to a SPAT test. The SPAT test
checks the repeatability of the FaroArm's X, Y and Z coordinates
throughout its range of motion.
In CAM2 Measure, launch the
Perform SPAT routine from the
D
IAGNOSTICS
dialog box. For
more information, see
“Diagnostics” on page 87.
Place the calibrated probe in the
calibration cone.
Start with the elbow of the
FaroArm to one side and slowly
take points on the calibration
cone as you swing the arm
around so that the elbow ends up
on the side opposite to that
which you started.
Ensure you take at least 100
points as you move the FaroArm.
Note the deviations in X, Y, and Z. The (Max-Min)/2 of each
coordinate should be within the FaroArm's accuracy.
N
OTE
: The FaroArm movement should feel fluid. Be careful not to
stress the arm while taking these points or get too close to an end stop
since stresses can be amplified near end stops.
If not using CAM2, simply export your list of points to Microsoft
Excel and calculate (Max.- Min.)/2 for each coordinate.
