=====Bertec Overview=====
The output from a Bertec force plate includes the forces and moments acting at the point of contact where a load is applied. Force plates with a JMP or VP designation output three channels of data: one vertical force (Fz) and two moments (Mx, My). All other force plates output six channels of data, including forces and moments in three directions (Fx, Fy, Fz, Mx, My, Mz).

Exceeding the maximum load that is outlined by Bertec,  may cause the force plate to behave nonlinearly. The overload capacity is 50%, this means the force plate can withstand up to 1.5 times the rated load without permanent damage. However, when using analog data, any load exceeding the rated limit may not be accurately measured.

===Bertec Force Plate Coordinate System===

The origin of the coordinate system is located at the center of the top surface of the force plate. The standard coordinate system is defined as follows:

The positive Y-axis points away from the force plate connector.

The X-axis points to the left when facing in the direction of the positive Y-axis.

The Z-axis points downward, following the right-hand rule.

All moment directions are also defined according to the right-hand rule.

===Bertec's Split-Belt Treadmill Dimensions===

Bertec's Split-Belt Treadmill **ITC-21-20 Standard Treadmill** 

The left half of the treadmill uses a coordinate system with its origin located at the inner corner of the arm block. In this setup, the Y-axis points forward, the X-axis points to the left (outward from the treadmill), and the Z-axis points downward. 

The right half of the treadmill also has its coordinate system origin at the inner corner of the arm block. However, in this case, while the Y-axis still points forward and the Z-axis points downward, the X-axis points to the left, which is toward the center of the treadmill.

For integration with motion capture software, the treadmill should be defined as two separate force plates, each measuring 70 inches by 22 inches (177.8 cm × 55.9 cm), with a 0.125-inch (0.32 cm) gap between them.
