Measuring method

Projection dimensions

1. 1
   These are dimensions measured when the measuring points are projected onto the base plane. They are base dimensions used for body modification.
2. 2
   If the gauge probe length is adjustable, measure by extending one probe by an amount equal to the height difference between the two surfaces.

   

Actual dimensions

1. 1
   These dimensions indicate the actual linear distance between points and are reference dimensions for use when measuring.
2. 2
   Measure with both probes first set to the same length (A=A').

   

Measuring point

1. Measurements should be taken at the center of the hole.
