cruinneas tomhais an iliméadair cliste

Tagraíonn cruinneas don earráid uasta incheadaithe i dtimpeallacht úsáide ar leith. I bhfocail eile, úsáidtear cruinneas chun cur in iúl

How close the DMM's measurement is to the actual value of the signal being measured.

Maidir le DMManna, is gnách go gcuirtear cruinneas in iúl mar chéatadán léitheoireachta. Mar shampla, is é an bhrí atá le cruinneas léitheoireachta 1 faoin gcéad ná: nuair is é 100 taispeáint an iliméadair dhigitigh.0V, féadfaidh an voltas iarbhír a bheith idir 99.0V agus 101.0V .

Specific values may be added to the basic accuracy in the detailed description. Its meaning is the number of words to be added to transform the rightmost end of the display. In the previous example, the accuracy might be marked as ±(1 percent plus 2). Therefore, if the GMM reads 100.0V, the actual voltage will be between 98.8V and 101.2V.

The accuracy of an analog meter is calculated in terms of full{{0}}scale error, not the displayed reading. The typical accuracy of an analog meter is ±2 percent or ±3 percent of full scale. The typical basic accuracy of a DMM is between ±(0.7 percent plus 1) and ±(0.1 percent plus 1) of reading, or even higher.
