6 Cleaning
In order to clean the device, unscrew the standard head.
Now attach the zero filter and carry out a cumulative measurement in measurement mode. If the
measurement value is not 0 for one particle size, you must make measurements until all the values are
zero. The system is cleaned by the pumping. You can now re-attach the standard head.
