This information pertains to the pre-November 2023 version of the Force Plate (FP-BTA) (shown here).
It is common for the force plate to provide a non-zero value after hard impacts. This may be the result of a permanent bending of the load cells. Zeroing the sensor in software can help, but that may only address the individual data collection event and require repeatedly zeroing.
For a more persistent solution, you can adjust the sensor’s potentiometer. Follow the instructions below to address this:
- Push the range switch to the -200/+850 setting.
- Attach the Force Plate to an interface, and connect your interface to either Graphical Analysis or Logger Pro software.
- Notice the sensor reading displayed in the sensor meter.
- Using a small slot-head screwdriver, rotate the right-side potentiometer to adjust the reading to zero.
If turning the potentiometer does not change the sensor reading, refer to the following article for further guidance.
Can my pre-November 2023 Force Plate be repaired?
