Calibration and Scale

Calibration and scale are crucial components in the functioning of a tachymeter, an instrument used to measure the speed of moving objects or the distance of stationary objects. The calibration process involves setting the tachymeter to ensure that its readings are accurate and reliable. This typically involves adjusting the internal mechanisms so that the tachymeter's scale aligns with known standards. For instance, in a watch tachymeter, calibration might involve synchronizing the watch's chronograph function with a precise timekeeping device to ensure that the elapsed time measurements are accurate.
