Measurement Tolerances - VOLTCRAFT VC1008 Anleitung

Measurement tolerances

Accuracy is given as ± (% of reading (= reading = rdg) + display error in digits (= dgt = no. of the smallest
places)). The accuracy is guaranteed for one year at a temperature of +23°C ± 5°C and a relative
humidity of less than 75% (noncondensing).
