AMTI calibration and settings (6 channels)

The following settings apply to AMTI analog force plates with 6 analog output channels.

AMTI force plate calibration parameters

Select the AMTI force plate type and click Calibration under the Force plate type heading to go to the AMTI force plate calibration parameters dialog. It contains the settings for dimensions and calibration factors of the AMTI force plate, see example in image below.

Force plate dimensions

Under the Force plate dimensions heading you should enter the dimension parameters (in mm) for the AMTI force plate. The parameters can be found in the user manual of the AMTI force plate.

Inverted sensitivity matrix

The Inverted sensitivity matrix is used to calibrate the force plate. Enter the values of the inverted sensitivity matrix (in SI-units) under the Inverted sensitivity matrix heading. For old AMTI plates the inverted sensitivity matrix was called calibration matrix. The values can be found in the manual of the AMTI force plate or can be loaded with Load from file from the diskette, which is attached to the manual of the AMTI force plate.

The file contains the Sensitivity matrix, which is then converted to the inverted when imported to QTM.

AMTI force plate settings

Select the AMTI force plate type and click Settings under the Force plate type heading on the Force plate page to open the AMTI force plate settings dialog.

There are four settings on the dialog: Analog board, Channel, Excitation Voltage and Gain, see example in image above.

Select the analog board where the force plate is connected from the Analog board drop-down list.

  • With Channel each signal is combined with its respective analog channel.

    On the Analog board (...) page the channel names can be renamed to match the signal names.

  • The Excitation Voltage is set to the bridge excitation voltage of each channel in the AMTI amplifier.

    The drop-down list gives you standard values, but you can also type any value for the setting.

  • The Gain is set to the gain of each channel in the AMTI amplifier.

    The drop-down list gives you standard values, but you can also type any value for the setting.

For more information about these settings see the manual of the AMTI force plate.
