3M Touchscreens - Touchscreen Calibration Procedure

Suzy Veitch

​Select the Main tab.

Click the Calibrate button.

Note: If you are using a TouchPen and you are in Pen/Finger mode, a dialog will ask whether you wish to calibrate using Pen or Finger. Calibrate using each option separately and when you are done, MT 7.12 will restore your TouchPen mode to Pen/Finger.

A calibration target appears in the lower left corner of the touch screen:

Note: If you press Escape or do not touch the screen within twenty seconds, the system automatically cancels the calibration process with no change to the current settings.

Touch the screen by positioning your fingertip to completely cover the green target. This position is calculated upon liftoff and when you remove your finger, the target should turn red.

When touching the calibration target, make sure to:

  • Face the monitor directly.
  • Perform the calibration in the position (sitting or standing) you expect to normally use the touch screen.
  • Touch the calibration target firmly and precisely with your fingertip. During Calibration, be careful to keep your fingernails and other fingers away from the touch screen as you touch the target.

Repeat these instructions for additional calibration targets.

Once you have calibrated the touch screen, a dialog box will appear to ask if you wish to test, accept or cancel this calibration.

If you select Accept, then the new calibration settings are automatically accepted.

If you select Test, then a Draw (refer to the Tools tab for more details) screen appears. When you exit Draw mode, a dialog will prompt, "Are you satisfied with the results?"

Selecting Yes will keep the new calibration settings.

Selecting No will restore the original (pre-calibration) settings.

If you select Cancel, the original settings will be restored without change.
