Activation of Self test moves

the center plate in the

−Z

direction, resulting in an

increase in the output.

DYNAMIC ACCELERATION SENSING DIRECTION

Acceleration of the package

in the

+Z direction (center

plate moves in the

−Z

direction) will result in an

increase in the output.

STATIC ACCELERATION SENSING DIRECTION

1. When positioned as shown, the Earth's gravity will result in a positive 1g output.
