mark (a gauge or instrument) with a standard scale of readings:the depth gauge is calibrated in centimetres
correlate the readings of (an instrument) with those of a standard in order to check the instrument’s accuracy:a separate control experiment is then carried out to calibrate the calorimeter
adjust (experimental results) to take external factors into account or to allow comparison with other data:the radiocarbon results would need to be calibrated to convert them to calendar ages
