AMTI portable calibration and settings (8 channels)

The following settings apply to AMTI portable analog force plates with 8 analog output channels.

AMTI 8-channel force plate calibration parameters

Select the AMTI 8 Channel (Portable) force plate type and click Calibration under the Force plate type heading to go to the AMTI 8-channel force plate calibration parameters dialog. It contains the settings for dimensions and calibration factors of the AMTI portable force plate.

Force plate dimensions

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

  • Old type of force plate
    Activate the Unit before SN 232 option, if you have a force plate with serial number lower than 232. These force plates have a "zero" level of 2.5 V. When calculating the force in a file, the data is always zeroed with the first 10 frames of the measurement. This is because the error is quite large and because of the 2.5 V offset you cannot use the standard option to remove the offset.

Calibration matrix

The Calibration matrix is used to calibrate the force plate. Enter the values of the calibration matrix (in SI-units) under the Calibration matrix heading. 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 portable force plate.

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

AMTI 8 Ch force plate settings

Select the AMTI 8 Channel (Portable) force plate type and click Settings under the Force plate type heading on the Force plate page to open the AMTI 8 Ch for plate settingsdialog.

  • First you must select the analog board where the force plate is connected from the Analog board drop-down list.

  • Then associate each signal from the force plate with its respective analog channel with the Channel settings.

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

For more information about the signals see the manual of the AMTI portable force plate.
