Aniqlik muayyan foydalanish muhitida ruxsat etilgan maksimal xatolikni anglatadi. Boshqacha qilib aytganda, aniqlik ko'rsatish uchun ishlatiladi
How close the DMM's measurement is to the actual value of the signal being measured.
DMMlar uchun aniqlik odatda o'qishning foizi sifatida ifodalanadi. Misol uchun, 1 foiz o'qish aniqligining ma'nosi: raqamli multimetrning displeyi 100.0V bo'lsa, haqiqiy kuchlanish 99,0V dan 101,0V gacha bo'lishi mumkin. .
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.
