To initiate a new factory calibration you have to click on the "Calibrate" button. It is recommended to

set “High performance mode” before starting the calibration.

To clear the existing calibration data and to set the EVM back to the uncalibrated mode you have to

click on the "Clear Calibration" button.

Both calibration and clearing the calibration take approximately 1 - 2 seconds to complete. During this

short time, the device is reset and all graphs will stop updating until the reset is complete.

Information

When performing factory calibration no object should be within 400

mm of the ToF sensor’s field of

view and use low ambient light (avoid high IR content).

“Enable De-Scattering” Check Box

Enable this checkbox to apply a de-scattering software filter to remove ghost targets from the

measurements results.

“Short Range Mode” Check Box

Enable this checkbox to switch to short-range mode. In short-range mode, the maximum

measurement distance reduces, and the measurement accuracy for close objects is improved.

Please have a look at the TMF882X datasheet for details about the short-range mode.
