hi prime,
It will be interesting to see your test results, please post the data when you have the time.

@ericgibbs,

*FINAL UPDATE*
After being advised by the manufacturer (likely for liability reasons) that the data cannot be trusted and will not be linear, I decided to run a calibration on the load cell with the same incorrect wiring configuration.

The calibration data turned out perfectly linear and repeatable with a scale factor of 2.16 (close to the original guess of 2.0).
The original data was fully salvaged and the student was able to complete her thesis on time.

Thank you all for your comments, your help was invaluable.


side note: does anyone know where 0.16 came from? Is this an example of ideal vs real-world error?
