19. Angle Zero Position at Shipment,
and Relation between Magnet Angle Position and Output
The relation between magnet angle position over the package and angle output data is as following
in Configuration at shipment (Zero Point configuration: default).
The relation between the angle output of the following figure, a package, and a magnet position has
a few degree error.
When the relation between an angle output and a magnet position correctly has to be decided, use
a zero point setup.

● Relation between Angle Position and Serial Angle Data
Relation between angle position and serial angle data is as following. When the zero point is
configured, the zero point is the angle position 0°.
