L1 Overall length
L2 Effective working length
D1 Ball diameter
Ø =4mm（M3）
Overall length L1
It is measured from the rear mounting face of the stylus to the center of the ball.
The effective working length L2
This is measured from the center of the ball to the point at which the stem will foul against the feature when measuring 'normal' to the part.
