Measuring Tolerances
Indication of the accuracy in ± (% of the reading ( = rdg) + indication errors in digits
(= dgt = number of the smallest digits)). The accuracy is valid for one (1) year at a
temperature of +23°C ± 5°C, at a relative air humidity of less than 70 %, not conden-
sing (with the multimeter part).
