Calibration (also known as adjustment) is the verification of the breathalyzer results with the results given by the standard of the measurement unit. During calibration, the sensor of the device is adjusted with the software so that the alcohol content in the blown air is the same on the display of the breathalyzer as the value on the reagent. Imatest's calibration routines are an example of parameter estimation from evidence. The estimated parameters are the intrinsics of the devices and their extrinsics in each capture.
