Calibration of Touch
Screen
When you replace the touch screen or MAIN board with a new one, the touch
screen must be calibrated. Or, depending on the setting position, the effective
point may slightly shift due to viewing angle. In that case, re-calibrate after the
instrument is set up.
Procedure to Start the Calibration of TOUCH PANEL
1. To start the calibration of the TOUCH PANEL, call up the DIAGNOSTIC
CHECK screen.
2. Press the MENU key to display the TOUCH PANEL CALIBRATION screen.
3. A target mark will be displayed from upper left corner to lower right corner
(total of 9 points). Touch the center of the target mark until it moves to the
next location.
4. After the calibration, you can confirm the recognized position. Touch
anywhere on the screen and the target mark tracks your touching position.
5. To return to the DIAGNOSTIC CHECK screen, press the HOME key.
