Polarity
6.4.1.1 Transverse Probe
Maximum flux density is measured if the lines of magnetic field
perpendicularly traverse the Hall element!
A positive reading is obtained when the lines of magnetic force enter the
white ceramic surface of the flexible transverse probe or the engraved black
cross of the transverse probe brass.
Figure 36 Measurements using a transverse probe
If the lines of magnetic force do not enter the Hall element at right angle, the
displayed value results from the true magnetic flux density according to the
following relation:
