D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

The resolution of a multimeter is the smallest part of the scale which can be shown. The resolution is scale dependent. On some digital multimeters it can be configured, with higher resolution measurements taking longer to complete. The resolution of a multimeter is often specified in the number of decimal digits resolved and displayed.
Specifying "display counts" is another way to specify the resolution. Display counts give the largest number, or the largest number plus one the multimeter display can show, ignoring a decimal separator.
5Ѕ digits resolution refers to the number of digits displayed on the display of a multimeter:
Ѕ digit can display either 0 or 1, while a ѕ digit can display a numeral >1 but not 9.
199999 Display count gives the largest number (or the largest number plus one):
5Ѕ digits resolution meter could show + or - values from 0 to 199,999 (200000).
