meetod, mille korral komparaatori ehk võrdlusmõõtevahendiga mõõdetakse nii etalonmõõdu kui ka kalibreeritava mõõduga reprodutseeritavat suurust ja fikseeritakse nende vahe väärtus
in this method, the value of the quantity provided by a material measure used as reference is compared with the value of the quantity provided by the material measure to be calibrated
The calibration of a material measure by comparison is typically used for calibration of weights, gauge blocks, resistance coils and similar material measures.
