Have some time to write, because my FOSS Milkoscan 133b has a problem with the “filter wheel not running OK” at the correct speed. For you other lab techies out there the procedure to check for this is to turn the key to horizontal and to type in Program 9824 from the Standby Menu. You should get a reading of 14400 if everything is alright. Slight variations from 14400 is OK, but preferably it should be constant.
When finished testing turn the key back to vertical and press the RESET button on the back of the machine.
Till next time,
Leon the Milkman
