Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
polarity; therefore greater B values indicate a stronger south polarity field (or a weaker north polarity field, if present).
2
The range of values specified for B
RES
is a maximum, derived from the cumulative programming bit errors.
