Police Fail to Correct a Linearity Problem on In-House Annual Inspection


Purpose:

To obtain an admission from the CFS scientist that the disclosed annual maintenance records indicate that the police failed to take any steps to correct control tests on inspection that indicated the instrument's response had shifted well beyond not only a 3 mg% tolerance, but well beyond a 10mg% tolerance.

To suggest to the CFS scientist that the calibration curve has shifted.

To suggest to the CFS scientist that the instrument's response is no longer as accurate and precise as it should be per manufacturer's specifications.

To suggest that police are not following their very generous 10 mg% tolerance SOPs.

To obtain an admission that measurement results on the instrument are no longer reliable.

To obtain an admission that the police did not stop use of the instrument and report the non-conformance to a superior.
