Step-by-Step Switching Directions
The Overview tab contains an animation that shows how to switch between a 6- and 12-position filter wheel. To switch between two filter wheels with the same number of positions, turn off the power to the motorized filter wheel, unscrew the thumbscrew on the front of the housing, and remove the front cover. The filter wheel can then be removed and another wheel can then be inserted. To switch between a 6-position and a 12-position wheel, follow the same process. However, when the front cover is reattached, you must adjust the settings of the motorized filter wheel to the new number of positions. This is done by holding the top two arrow buttons for approximately three seconds and then changing the filter position value to either six or twelve.
