Application:
Internal calculation from plunger displacement supports direct reading with dedicated fixtures. Catalogue examples cover countersink diameter, groove width, countersink/groove depth, outside radius and inside radius using cone/ball contact arrangements and coefficients A, B, C and origin offset.

Dimensions:
No separate 25.4/50.8 mm dimensional drawing values are stated on these family pages.

Remark:
Calculation resolution is 0.001 mm; catalogue cautions that sub-micrometer settings may make the fourth-place digit unreliable for some coefficient combinations.
