Measurement Resolution

Smallest increment a measurement device can reliably display or distinguish.

Examples

01A caliper with a measurement resolution of 0.01 mm is not suitable for a tolerance of 0.02 mm.
02The supplier review rejects a gauge because its measurement resolution is coarser than one tenth of the tolerance.
03When measurement resolution is too coarse, every reading falls into the same few values, and the control chart cannot show real changes.
