The magnetic field in each of the three orthogonal
directions is computed from the corresponding coil's
digitized value and the magnetic field scaling factor.
The magnetic field in milligauss units is computed by first
adding 0.5 to the digitized value and then multiplying by
the appropriate scaling factor (see the magnetic field scale
The magnetic field is a positive floating point number.
Using the scaling factors provided, the units of measure are
milligauss. The minimum field recordable by the EMDEX along
a single axis is 0.05 milligauss. The maximum field is
