Usage Note
Calibrer means to measure or adjust something to a precise standard, as in calibrating an instrument. Figuratively it means to tailor or size something carefully — une réponse bien calibrée is a carefully measured response. The noun calibre refers to both the diameter of a bullet and, informally, to the 'class' or quality of a person.
