It is possible to calibrate one current channel at a time or both at the same time.

According to the choice, the user should check the check boxes related to the channels to

calibrate, select the number of samples to average and the delay between samples.

Pressing the “Calibrate” button, the calibration procedure starts and it consists of:

•

Writing device configuration bits and setting calibrators in the middle of the range

•

Reading and averaging samples

•

Calculating the calibrators to reach the target measure calculated above.

Once the calibration process is completed correctly (Figure 11), it is possible to write in the

shadow memory the calibrators or to calibrate next phase selecting the proper check box

and pressing “Calibrate” again.

If the calibrators are out of range, the user is asked to go back and modify the board

parameters and/or the constant pulse to achieve the calibration.
