In a previous email/post, I described that you should take ultrasonic transducer measurements in such a way that 1 year from today you will be able to use the data along with your additional notes and protocols and have an understanding and a level of confidence in the data as if you took the data today. AND, if you were to take the data again today, you would end up with the same measurements - that is confidence.

So why do I mention 1 year? That is because root cause analysis can last up to one year or even more. Unfortunately, during ultrasonic transducer root cause analysis, tensions are high and answers seem just around the corner. This results in protocols, documentation, and diligence going out the window (then going SPLAT!).
