I follow meticulous procedures, as I am certain that you do as well, to minimize error from contaminated data, proper reading and measurement of samples and maintaining calibration of devices. In general, should an anomaly be reported by the equipment, it is my FIRST thought that the test may be faulty and that possibility eliminated. It seems with the TSA their machines can never be seen as fallible, just like their people. We must be led to believe in their perfection and if we question it or their procedures, it is further evidence that we are indeed the criminal that they suspect us to be just because we had the audacity to buy a ticket to get on an airplane.
