Calibration check (in the context of the Intoxilyzer)

The Crown, the police, and their experts will say that a cal. check or calibration check is run during each Esc Esc sequence or each ACABA subject test sequence. The defence will say that a control test is run during these sequences at only one data point, i.e. 100 mg/100mls. A control test is a rough test, in the field, of calibration at 100 or whatever data point the police office chooses (by using for example 80 or 110 standard). In practice police in Ontario use 100 standard.
