All sensors are pre-calibrated ex works on delivery.

If required, the sensor of the signature pads can also be recalibrated manually. This may be necessary if the display of the signature is not exactly under the pen tip.

The service menu "Calibration" is activated by touching the sensor in the upper left area while inserting the device into the USB port. Two crosses appear one after the other in the upper left and lower right corner, which must be touched exactly. The instrument will then restart.
