3.2.1 Touch screen calibration
Touch screen devices are pre-calibrated at the factory. This feature offers great advantages especially for replace-
ment parts since recalibration is usually no longer required when replacing a device (identical model/type). B&R
still recommends calibration for best results and to optimally adapt the touch screen to the needs of the user.
During the calibration procedure, the specified point must be pressed four times in succession within a certain time.
If calibration is not carried out correctly, an error message appears.
Information:
A stylus pen (e.g. 5AC900.1100-01) is recommended for touch screen calibration.
