Točnost se odnosi na najveću dopuštenu pogrešku u specifičnom okruženju upotrebe. Drugim riječima, preciznost se koristi za označavanje
How close the DMM's measurement is to the actual value of the signal being measured.
Za DMM, točnost se obično izražava kao postotak očitanja. Na primjer, značenje točnosti očitanja od 1 posto je: kada je zaslon digitalnog multimetra 100.0V, stvarni napon može biti između 99,0 V i 101,0 V .
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.
