Data items
Table 3 – 1 lists a number of data items. They contain measured data, verification data and error data. The
verification data can be used to check the results of certain steps in the measuring sequence. The temperature
status indicates the validity of the measured data. The error data provides low level error information about the
temperature measurement (refer to section 3.4).
