calibration of i40 bidata speed

[georgeo]

Thanks so much for clarifying this and understanding that the transducer signal has a non-linear error. So for my i40 Bidata I will need to decide at which speed it is most important to me to calibrate to. If I am interested in high speed accuracy I'll need to slow it down a bit. If I'd prefer more accuracy at slow speeds I'd leave it alone. If I want wide range accuracy, then a different unit with multi point calibration is needed.

This is all very clear now. Thanks for the help!
