WitrynaFor example, an accuracy of ± (2%+2) means that a reading of 100.0 V on the multimeter can be from 97.8 V to 102.2 V. Use of a digital multimeter with higher accuracy allows … WitrynaHowever, if we measure a voltage of 0.09V on the same scale, then the absolute uncertainty will be: (0.09 × 0.025) = 0.00225. + (3 × 0.01) = 0.03. = 0.03225 ⇒ 0.03V. This demonstrates why it's important to use the most sensitive scale on the DMM that …
