Calibration Tool

When you observe touch performance starting to degrade, under consistent environmental lighting conditions, the Microsoft Surface vision system may need to be recalibrated.

Calibrating a device made for Surface

The calibration processes consists of taking white and black snapshots of the screen:

  • The white snapshot (also called the white reference image) is a snapshot of the screen surface when it is covered by the white side of the calibration board.

  • The black snapshot (black reference image) is a snapshot of the screen surface when it is covered by the black side of the calibration board.

To run calibration

  1. Preparing the device made for Surface for calibration:

    1. To ensure optimal calibration, allow the device made for Surface to be powered on for at least one hour, allowing the device to warm to normal operating temperatures.

    2. Clean the screen of the device. Follow the user manual for cleaning instructions.

    3. Be sure to have the calibration board ready. If you do not have a calibration board, contact the manufacturer of your device made for Surface.

    4. Connect a keyboard to the USB port.

    5. Turn up the speaker volume.

    WarningWarning
    Take care to ensure that the On Screen Display (the device menu activated by pressing the device power button) does not appear during the calibration process. This will affect the calibration accuracy; it may cause problems in the touch performance and also display artifacts in the user interface.

  2. To perform a calibration, locate the shortcut for the calibration tool on the Windows desktop or in the Program Menu. The tool is located in the Surface folder: C:\Program Files (x86)\Surface\v2.0.

    noteNote
    If a User Account Control window appears, click Allow.

    If the tool detects that the operating temperature is low (less than 32° C), you will receive a warning message.

    To exit the tool without running calibration, press Alt+F4.

  3. Remove all items from on top of the device made for Surface, place the white side of the calibration board so that it completely covers the screen and press Enter on the keyboard.

    This step may take 30-90 seconds. When this step is complete, you will hear a sound.

    WarningWarning
    Once calibration has started, you should not exit the tool. Exiting the tool during the calibration process could damage the device made for Surface.

  4. Place the black side of the calibration board so that it completely covers the screen, press Enter on the keyboard.

    This step may take 5-15 seconds. When this step is complete, you will hear a sound.

  5. Remove the calibration board.

    Calibration data is then analyzed and saved. You will see a message indicating that calibration completed successfully.

  6. Press Enter on the keyboard to close the tool.

    You have completed calibration.

WarningWarning
In the event an error occurs during calibration, you should receive an error message. If calibration fails more than three times, or if a catastrophic event is detected, you will be directed to contact the manufacturer.
