Compensated Temperature Range

The compensated temperature range defines the limits of operation for a specified measurement accuracy.  e.g. A pressure sensor has an accuracy of 0.25% full scale over a compensated temperature range of -20 to +80 degC.

Since temperature errors are often significant for many measurement devices, a manufacturer will incorporate digital or analogue temperature compensation.  If the measurement device is used outside the compensated temperature range, the accuracy statement is no longer valid, because the device has not been tested or compensated for that temperature.
