3.2. Current loop
Loop over current from 10 to 100mA by steps 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.

3.3. Rate
The following test aims at checking the feasability and behaviour stability of the FWs operated at higher rates (= higher speed). The baseline rate = 100, corresponding to an angular speed of 360 degrees in 18.75 seconds.
