TlvMeasurementAccuracyRange: ObjectSchema

This struct represents the accuracy of a measurement for a range of measurement values. Accuracy shall be expressed as a maximum +/- percentage of the true value, a maximum +/- fixed value of the true value, or both.

• If both PercentMax and FixedMax are indicated, then for a given true value in the range between RangeMin and RangeMax,

◦ the reported value shall be less than or equal to the sum of the true value, FixedMax and PercentMax percent
  of the true value.

◦ the reported value shall be greater than or equal to the true value minus the sum of FixedMax and PercentMax
  percent of the true value.

• If only PercentMax is indicated, then for a given true value in the range between RangeMin and RangeMax,

◦ the reported value shall be less than or equal to the sum of the true value and PercentMax percent of the true
  value.

◦ the reported value shall be greater than or equal to the true value minus PercentMax per

cent of the true value.

• If only FixedMax is indicated, then for a given true value in the range between RangeMin and RangeMax,

◦ the reported value shall be less than or equal to the sum of the true value and FixedMax.

◦ the reported value shall be greater than or equal to the true value minus FixedMax.
