-Setting the [[https://www.c-motion.com/v3dwiki/index.php/FP_ZERO|Force Platform Zero]] parameters for Instrumented Treadmills can be quite challenging because the unloaded frames aren't readily identified automatically, and one would prefer to use all of the unloaded frames for determining the zero range.\\+Setting the [[visual3d:documentation:pipeline:force_commands:fp_zero]] parameters for Instrumented Treadmills can be quite challenging because the unloaded frames aren't readily identified automatically, and one would prefer to use all of the unloaded frames for determining the zero range.\\

-**Why is this parameter so important?** When there are two platforms in the treadmill there may be times when one foot is on two platforms (the other foot is not). The transitions from one foot on one platform to two platforms (or vice-versa) often causes an artifact (sudden change) in the force signal that is about the magnitude of the minimum force threshold. This artifact is most commonly seen with a front to back treadmill than a side to side. This parameter is used to resolve this discontinuity by using an alternate minimum force surrounding known contiguous force intervals to include relevant force readings that may be below the noise threshold, but still rising or lowering from the REDUCED_FP_MINIMUM value. This avoids the FP Minimum value discontinuity when FP transitions occur and combines the two signals into one force and cop signal, then reapplies the force minimum threshold.\\+
