What is count tolerance on multimeter?

Count tolerance on a multimeter refers to the acceptable range of variation in the display reading, often specified as a percentage of the reading plus a fixed number of counts. For example, a multimeter might have a tolerance of ±1% + 2 counts, meaning the displayed value could be off by 1% of the reading plus or minus 2 digits. This tolerance helps users understand the precision of the measurement and the potential error in readings. It is crucial for ensuring accurate measurements in various applications.
