The sensor is calibrated to display volume magnetic susceptibility (c
vol
) for a 22mm hole.
For larger hole diameters, the displayed value will be lower than true c
vol
. An approximate value
of c
vol
can be obtained by multiplying the displayed reading by the scale factor in Table 4.

Hole diameter (mm) Scale factor * for c
vol
23.0 1.000
24.0 1.418
25.4 1.739
* Average value determined by tests on 20 samples.
