Projected Dimensions

1. These are the dimensions measured when the measurement points are projected into the reference plane, and are the reference dimensions used for body alterations.
2. If the length of the tracking gauge probes is adjustable, make the measurement by lengthening one probe by the amount equivalent to the difference in height of the two surfaces.

Actual-Measurement Dimensions 

1. These dimensions indicate the actual linear distance between measurement points, and are the reference dimensions for use if a tracking gauge is used for measurement.
2. Measure by first adjusting both probes to the same length (A=A").
   NOTE: Check the probes and gauge itself to make sure there is no free play.
