The load cells need to be calibrated to work. Here is an old video that shows how to do it. It is the same process today:

Here is how the calibration window looks:
There are a few tricks to note:
- “Torque arm length to load cell”. This is the distance from the middle of the brake axle to the load cell
- It is not necessary to place the load cell on top of the load cell. If you place it at a different spot, enter the distance from the middle of the brake axle to the place where the weight is. You can for example use an extension arm and place the load further away from the brake, thereby reducing the need of a heavy load
- For high accuracy, select a load for the load cell at least 20% of load cell rating and let YourDyno stay on for some minutes for all temperatures to settle before making a calibration
