Michigan DataMaster Refusal - Invalid Sample?
After these initial steps of the DataMaster machine, a sterile mouthpiece is inserted into the breath tube. The machine asks: “SUBJECT REFUSED? (Y/N)”. The operator has 1 minute to answer this question or else the test must be restarted.
If the subject agrees to take the test, the officer types “N”, and the display flashes “PLEASE BLOW”. As the subject blows, the words “PLEASE BLOW” will stop flashing and remain constant. The subject must continue to blow until the machine reads “TEST RESULTS”.
If a subject blows into the machine and “INVALID SAMPLE” is displayed, the machine has detected mouth alcohol. “INVALID SAMPLE” is different than “INCOMPLETE”. “INCOMPLETE” is an indication of an inadequate breath sample. The operator should receive a steady tone indicating that an acceptable breath sample is being received. The tone has been described as a high-pitched beeping sound. The machine determines whether an adequate air sample has been provided. One difference between the BAC DataMaster and the DataMaster DMT model is that the “technical refusal,” in which “incomplete” is displayed by the instrument, has been removed. The DMT model simply allows the subject 2 minutes to provide an adequate sample, after which a refusal will be generated.
If your test reveals an invalid sample, we will discuss how this impacts your case.
