Heater Response Time on Guth 2100


Purpose:

To further challenge the Crown's suggestion that the anomalous low cal. checks that occurred in this breath truck were not caused by a door opening from time to time in winter.

To support the O'Connor application for production of contemporaneous documentation by the QT who obtained the group of low cal. checks. Documentation would shed light on possible causes of the low cal checks, any troubleshooting attempted, and the likelihood that their cause was a problem with Intoxilyzer precision.
