5.1. General
Only
the values assigned tolerances or the limits
declared constitute guaranteed values. The values
without any tolerance are given as indications.
5.2. Characteristics
The accuracy is ± [% of the reading (R) + number of
representation units (digits or D)] in the reference
conditions (see appendix).
