Resolution refers to a minimum reading can be measured. In 4.000 range, the resolution is 0.001, it is usually called a "word."

Accuracy is generally called "precision" or “uncertainty”, eg. ± (1.5% + 3), which specifies the measurement uncertainty of "measured value of 1.5% plus a “word””, described as follows:

The full range of 4.000, for the measurement of 2, the uncertainty is to be calculated:

± (2.000 × 1.5% + 0.003) = ± 0.033
