To configure force plates for analog data capture:

1. Go to the Resources pane > Systems tab, click the Go Live button.

2. In the System tab, right-click the Devices node, point to Add Analog Device and select the proper force plates.

The selected force plate node automatically expands to display the newly created device. If the appropriate type is not displayed, contact Vicon Support.

3. In the Properties section at the bottom of the System resources pane, select Show Advanced.

4. In the General section

• Either load the manufacturer’s Calibration File.
• OR, enter the Calibration Matrix 6×6 Matrix values manually

5. In the Source section

• From the drop-down list, select a Source to which the device is attached (i.e. Lock+ or Giganet MX)
• Select the appropriate pins for the force plate channels.
• Select the Gain for the Source from the choice of gains available for the Lock+.

Please Note: Expand force plate node to expose the Force, Moment and CoP (Center of Pressure) channels. A Green Arrow indicated a connected source device and a Yellow yield indicates that a channel has not been assigned a pin.

6. In the Dimensions section, add in values from force plate manufacturer’s manual if not already entered

7. In the Positions section, position the force plate in respect to the wand and the origin of the plate.

8. In the Orientation section, orient the plate so it makes sense in respect to your capture volume.

9. In the Origin section, add in values from force plate manufacturer’s manual if not already entered.

10. To tare the force plate at zero load:

• Complete a hardware zero with the force plate Amplifier, if possible.
• Click the Zero Level browse button and enter the matrix properties.
• You can also tare the force plate by right-clicking on the force plate name in the System resources tree and selecting Zero Level.

11. In the capture volume, have someone step onto the force plate. You should see the force vector display in real time.

• Switch to a Graph View pane. If necessary, select Components from the Graph Type drop-down list. A real-time graph of the Force output is displayed. Verify that the vertical (Fz) force component is equal to [known mass * 9.81].
