Annual Inspections Done Without Reference to Manufacturer's Specifications

Purpose: To confirm that when new instruments are being evaluated, various solutions are used between 50 and 400 mg/100mls. To confirm that when new instruments are being evaluated, the specified accuracy requirement is +/- 5 percent of the BAC with a precision requirement of +/- 3 mg/100mls under 100 mg/100mls and +/- 2.5 percent for readings greater than 100. To confirm that the purpose of such evaluation is to ensure the accuracy and reliability of breath tests. This proc

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 tol

Use of Wet-bath Simulator in Winter Cold Temperatures

Purpose: To cross-examine a CFS scientist on use of Guth 2100 wet-bath simulator under Canadian cold operating conditions To build a case for O'Connor production of contemporaneous documentation by the QTs who obtained the groups of low cal. checks in the breath truck in winter. During Direct Examination, the CFS expert had suggested in response to the Crown's request for the simplest explanation for anomalous low cal. checks, that the door being left open on the breath truck

Wet-bath Simulators Manufacturer Specs

Purpose: To obtain an admission from a CFS scientist that expectation of ATC Best Practices Recommendation is for annual inspection of wet-bath simulator to ensure it meets manufacturer's specifications To obtain an admission from a CFS scientist that manufacturer's specification for a Guth 2100 simulator is 34.00 +/- .05 degrees C, not just 34.0 +/- .2 degrees C. #inspection #simulator #wetbath #manufacturersspecifications #3400

Being Intolerant Depends on Humans not the Machine

Purpose: To challenge the Crown's assertion that the AI will automatically shut down if anything is out of tolerance or ATC or manufacturer's specifications. Let's suppose the Crown's expert says this about the Intoxilyzer 8000C: "If the calibration check is outside the acceptable range, you’re not going to be able to proceed with testing." The expert is saying in other words, the instrument is smart enough to make sure that cal. checks are foolproof, and you can't proceed wi

Distorted Concept of "Accuracy", "Precision", and "Reliability"

Purpose: To remind the Court of the concept of "reliability" used by the SCC in St-Onge. To educate the Court as to the definitions of "accuracy", "precision", and "reliability" used by Brian Hodgson in his paper relied on by the SCC in St-Onge. To focus on drift in accuracy and precision over time from: the manufacturer's specifications, and/or the accuracy and precision of the 8000 that was evaluated, and/or this specific instrument when first placed into service, as compar
