The sensor was calibrated in the CC varsity weight room. Ten voltage readings with weights up to 765 lbs (347 kg) were sampled so that a fit could be found between force and voltage.
After a fit was found from the calibration, drop tests were performed in the Ritt Kellogg Climbing Gym to measure the forces generated during various types of climbing falls on several materials. The three scenarios tested were large falls (7.3m) on dynamic (stretchy) climbing rope using a dummy weight (pictured), smaller falls (~2m) with people as weight, and short (<1m) falls on static (non-stretchy) nylon and dyneema slings using the dummy weight.
Below are some videos of the various drop tests. More videos can be found on a google drive here.

A smaller fall, still on a dynamic rope, with me as the weight (80 kg).
Using the 85kg dummy weight to break a static (non-stretchy) dyneema sling. This is an example of why you should not use climbing equipment in a way that it was not designed for.
