This thread can be used to discuss the inaccuracies and issues concerning weigh-ins. In particular, I made this video to address the Darren Till "trick" that is common in many threads. As you will see, even a slight change in level ground can effect the reading because the load cell is made to measure force in a perpendicular direction, not angular. The circuit for a digital scale uses four load cells to average the platform. If you only used one cell in the middle of the platform, the tilt would cause irregular readings. The commission needs to have a spotter checking fighter stance on the scale to be centre, and standing straight. This is how the load-cell (strain gauge) is calibrated). In my video the scale reads a one-pound differential just by moving it a few feet away to another area of the floor. I was able to get a few pounds by stepping back like Darren Till. This goes for any digital scale, no matter how expensive, or inexpensive. They all use similar technology. Errors in Accuracy: Leveling the Scale If the scale is off balance, it will cause an incorrect weight. Test the location of your scale to be sure that it is sitting on a level surface, and check that the scale’s little feet are all on and even. Also turn the scale over from time to time and clean the bottom since too much debris might interfere with the way the scale sits.
