Figure 7-1. Direction of Sensitivity

The magnetic flux that travels from the bottom to the top of the package is considered positive in this data sheet.

This condition exists when a south magnetic pole is near the top of the package. The magnetic flux that travels

from the top to the bottom of the package results in negative millitesla values.
