what he said ^^^ and just to make things worse, if one considers six sigma and anova gage r&r regarding measurement, precision is the resolution of a measurement. accuracy is the ability to reproduce that measurement consistently against a known standard.

precise: an instrument (a tuner for example) manufactured within tight tolerances.

calibration: performance of that instrument validated against a known standard.

accuracy: repeatabliity of said validation to the known standard.

then there is the factors of how someone is using and reading the instrument......
