Hi all. I have recently taken on a project that involves a device that is instrumented with strain gauges (think of it as a cantilever tube with strain gauges at one end...the instrument details aren't too important for the question). Now, this instrument has SO many errors that I do not know how to deal with it without redesigning the device from scratch. The professor I am working with seems keen to keep the design as is and keeps on telling me that the errors can be accounted for. This is my problem. How can errors like hysteresis, a lack of repeatable zeroes, random gauge sensitivity issues, and literally zero repeatability be accounted for to give meaningful results? I wanted to see if anyone could guide me a little before talking to the professor as I am relatively inexperienced and want to know a little better about this before I go and talk to him. I am reading up on experimental errors now but nothing seems to help when it comes to this flawed instrument. Thanks in advance.
