Note 1

Note 2

Note 3

The measuring range is limited by the sensitivity and offset.

Offset speciﬁed as Output @ 0 °.

The frequency response is determined by the sensing element’s internal gas damping.

The output has true DC (0 Hz) response.

Note 4

Note 5

The cross-axis sensitivity determines how much inclination, perpendicular to the measuring

axis, couples to the output.

For optimum zero point accuracy, mounting angle of the part can be adjusted.

Notes:

•

It is important that the part is parallel to the mounting plane, and that the output equals the zero value when sensor is in zero position.

Zero position: Please note the picture above which provides information on how the output of the accelerometer behaves in different

circumstances when assembled. Please also note that you can rotate the part around the measuring plane for optimum mounting location.
