... it seems nobody has been able to get the court to recognize that calibration/maintenance of radar should and needs to be done.
My question is if there IS a requirement for calibration/maintenance of blood alcohol machines? Are they required to keep these types of records for blood alcohol machines, or are they in that same category as radar where a "self test" before and after is enough?

How ever unlike radars they are not tested daily but are tested every week, 2 weeks, etc depending on the program approval and instrument used.
