Soft Foot
The Soft Foot calculation is equal to ((the magnitude of the movement of the foot)
divided by (dimension C — Bracket to Sensor distance)) divided by the Soft Foot
Tolerance. The default Soft Foot Tolerance = 0.5 mils / inch. If Soft Foot has been
defined for the job, the data is evaluated as follows:
•
OK
The measurement for Soft Foot is within the specified tolerance.
•
X
The measurement is from 1 to 2 times the specified tolerance
(1x tolerance < measurement < 2x tolerance).
•
XX
The measurement is from 2 to 3 times the specified tolerance
(2x tolerance < measurement < 3x tolerance).
•
XXX
The measurement is greater than 3x tolerance.
This method does not display a number as the machine is being checked for soft
foot (to prevent you from mistaking this number for a shim correction).
Frame Distortion Index (FDI)
The FDI calculation is equal to ((the magnitude of the movement of the foot)
divided by (dimension C — Bracket to Sensor distance)) multiplied by two times the
foot to foot distance. If FDI has been defined for the job, the data is evaluated as fol-
lows:
•
“No Box”
The measurement condition is excellent (less than 2.0).
•
“Clear Box”
The measurement condition is acceptable (between 2.0 and 3.0).
•
“Dark Box”
The measurement condition is out of tolerance (greater than 3.0).
