### <a name="AccelerationConfidence"></a>AccelerationConfidence
This DE indicates the acceleration confidence value which represents the estimated absolute accuracy of an acceleration value with a default confidence level of 95 %.
If required, the confidence level can be defined by the corresponding standards applying this DE.
- `n` (`n > 0` and `n < 101`) if the confidence value is equal to or less than n x 0,1 m/s<sup>2</sup>, and greater than (n-1) x 0,1 m/s<sup>2</sup>,

**Unit:** _0,1 m/s<sup>2</sup>_
**Categories:** Kinematic information
**Revision:** _Description revised in V2.1.1_
NOTE: If an acceleration value is received and its confidence value is set to `outOfRange(101)`, it means that the value is not valid and therefore cannot be trusted. Such value is not useful for the application.
