1. Filter Wheel control loop procedures

2. Conditions

All tests described can be executed from SAFE MODE of from SPECTROSCOPY.

3. Threshold Tuning

3.1. Threshold parameter optimisation Photometer filter wheel

A loop over steps 3 & 4 can be implemented for a number of thresholds

4. Current loop

4.1. Photometer filter wheel

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.
