= Current loop =

Loop over current from 10 to 100mA by step of 10. For each setting, performs nturns *OPEN LOOP* movements of 360 degrees (default = 3). Open loop movement means that the wheel is driven for a given time, depending on the size of the movement and the rate. Consequently, the movement might finally not be of the expected size.
