Police No Longer Follow ATC Best Practices Respecting Tolerance


Purpose:

To demonstrate that when the particular instrument was first placed into service, the tolerance verified by the independent authorized service centre for each of three test values was +/- 3 mmg/100mls.

To demonstrate that the initial verification matched the manufacturer's published specifications.

To demonstrate that when the particular instrument is subsequently being annually checked at each of the three test values, the checklist indicates that the acceptable tolerance is now +/- 10 mg/100mls.

To demonstrate that the instrument's calibration is no longer being verified in accordance with the manufacturer's specifications.

To demonstrate that the police service is not adhering to the best practices document of the ATC.
