Cleaning aerosol sensor optical glasses
The aerosol sensor optical glasses have to be cleaned if, when calibrating
the aerosol sensor, the photomultiplier voltage is more than 15% higher than
the value of the last calibration.
The sampling tube, aerosol inlet tube and gravimetric filter have to be de-
tached to access the optical glasses.
