I’ve been using a multimeter for a long time but never really thought about the term "display count." Lately, I’ve come across it in some tutorials, but I didn’t quite understand what it means. Can anyone explain it in simple terms?

The term “display count” in a multimeter refers to the maximum number of digits the display can show. It tells you the resolution of the multimeter, which affects how precise your readings can be.
For example, if a multimeter has a display count of 2000, it can show readings from 0000 to 1999. This means that when measuring voltage, current, or resistance, the highest reading you can see is 1999 units before the multimeter switches to a higher range or shows an overflow.
Let’s say you are measuring voltage with a 2000-count multimeter. If the setting is on the 2V range, the meter can show values up to 1.999V. If you measure 2.000V or higher, the multimeter will need to switch to a higher range to display that value, or it may show an error or “overload” indication if it’s beyond its capability.
For example, if you try to measure 3V while on the 2V range, the multimeter will likely display an “OL” (overload) warning or an error to indicate that the voltage exceeds the selected range. You would need to switch the multimeter to a higher range, such as 20V, to read 3V accurately.
If you set the multimeter to the 20V range, the maximum it can display is 19.99V. This is because a 2000-count multimeter can show readings up to 1999 in any range, so on the 20V range, the highest voltage it can display before switching ranges or showing an overload is 19.99V.

Not quite—a 6000-count meter doesn’t extend the 2V range to 5.999V. The range is fixed by the multimeter, not the count.
In the 2V range, both 2000- and 6000-count meters typically max out at 1.999V. A 6000-count meter would show up to 5.999V only if it's on a 6V range, not 2V.
So, a higher count means better resolution, but the voltage range itself stays the same unless the meter has a higher range setting.

Display count represents the maximum number of digits the multimeter display can show accurately. It’s often used to indicate the resolution of the multimeter.
For example, if a multimeter has a display count of 2000, it means it can display values from 0 to 1999. Similarly, a 4000-count multimeter can display values from 0 to 3999.
