Determine the accuracy and repeatability of the data below as a percent of output span:

Solution

Accuracy indicates the closeness of the reading to the real value. Where as repeatability indicates how many times the value is repeated under the same conditions. For accuracy take the average of the three observations.

Temperature Accuracy. Repeatability
