Why use the term “Counts”?
Slaughter publishes some specications using COUNTS which allows us to provide a better indication of the tester’s capabilities
across measurement ranges. A COUNT refers to the lowest resolution of the display for a given measurement range. For
example, if the resolution for voltage is 1V then 2 counts = 2V.
