This document provides information about measuring errors of analog and digital instruments. For analog instruments, accuracy is typically expressed as a percentage of the full scale reading. The error can be ±3% of the measured value if it is in the last third of the scale, but increases if further from the full scale value. Digital multimeters have resolution defined by the number of display digits, such as ±0.05% for 31⁄2 digits. They may also have automatic or manual range selection to ensure accurate readings in the optimal scale region.
