This entry refers to Go Direct® Force Plate (GDX-FP) and Force Plate (FP-BTA)—manufactured after November 2023. For more information, see Which force plate do I have?
If your force plate readings are not consistent with expected readings, you may find calibration necessary. Calibration of this vintage of force plate requires special attention to the following details, as a poorly executed calibration can make your readings worse.
For general calibration information, see How do I calibrate my sensor?
Perform a 2-point calibration
- The first point is zero with no mass on the force plate and the force plate resting on a level surface.
- The second point should be a weight that is at least 25 kg (or 50 lb).
⚬ Do not exceed the range of the force plate.
⚬ Note: 1 kg weighs 9.8 N.
⚬ Gymnasium weights can be used, but you should verify their actual mass by some independent means. - The weight should be symmetrical and placed accurately at the center of the force plate.
⚬ Do not use a person as the second calibration value, as they will not be easily centered.
⚬ You may consider placing a large metal washer at the center of plate upon which to rest the weight. This may be helpful in ensuring the force is applied to the center of the force plate.
