- What are digits, accuracy, and resolution with a DMM
This blog post describes the display digits of a digital multimeter's relationship with your measurement resolution, accuracy, and speed

Technician A says that a DMM rated at 4 ½ counts of resolution displays only four digits Technician B says that in DMMs rated with 3 ½ counts of resolution, the half count can only be displayed as a 1 or zero

These have been dubbed 3 3 4- and 4 3 4-digits respectively This description is even less intuitive than it was for 3 1 2-digits A better approach which is now displacing the fractional digits is to specify the number of "counts" that may be displayed For example, the 3 1 2-digit display is described as 2000 count (1999 plus the reading of 0)
- Understanding Digital Multimeter (DMM) specifications
The half digit, considered the most significant digit, displays a 1 or remains blank A 4½-digit DMM can display four full digits and a half, indicative of higher resolution Display Counts Display Counts tell you what a DMM will display before it changes to the next range For example, a DMM has 50000 counts
- What Is Resolution (Digits) Mean in DMM Specification? - NI
The first digit, 5 digits, means you can display up to 5 digits For 5 digits, 00000 ~ 99999 can be displayed, but for 5 ½, this can be displayed when 000000 ~ 199999 are displayed In other words, if ½ is used, it is used when the first digit is represented by only 0,1

The terms digits and counts are used to describe meter’s resolution DMMs are grouped by the number of counts or digits they display 31⁄2-digit meter can display three full digits ranging from 0 to 9, and one “half” digit which displays only a 1 or is left blank A 31⁄2-digit meter will display up to 1,999 counts of resolu-tion

More the number of digits, more the resolution Well, the “half digit” or 1 2 can only display a “1” or “0”, The numerator of 1 2 is the maximum digit that can be shown (1) and the Denominator is the total number of digits possible (2)
