The table outlines the probe contact
diameter and the minimum tubular diameter which can be normally
measured relative to the probe type.

Note : This table is only a guide and
is not absolute. Minimum Pipe Diameters are indicated which will
allow the instrument to resolve 0.080" (2mm) wall thickness or
a 0.040" (1mm) deep pit on a 0.120" (3mm) thick wall.
Material properties, surface conditions and couplant also effect
results.
