This information pertains to the pre-November 2023 version of the Force Plate<\/a> (FP-BTA<\/nobr>) (shown here).<\/p>\n<\/div>\n

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.<\/p>\n

For a more persistent solution, you can adjust the sensor’s potentiometer. Follow the instructions below to address this:<\/p>\n

\n

    \n
  1. Push the range switch to the -200\/+850 setting. <\/li>\n
  2. Attach the Force Plate to an interface, and connect your interface to either Graphical Analysis or Logger Pro<\/em> software.<\/li>\n
  3. Notice the sensor reading displayed in the sensor meter.<\/li>\n
  4. Using a small slot-head screwdriver, rotate the right-side potentiometer to adjust the reading to zero.<\/li>\n<\/ol>\n

    If turning the potentiometer does not change the sensor reading, refer to the following article for further guidance.
