Cleaning 2.5 µm Calibration Impactor
The calibration impactor should be cleaned prior to every use, using it to
perform a Standard Calibration (size correction) on the instrument, as
described in the Operations
section.
1. Unscrew Impactor. Check O-ring on the impactor base.
2. Clean outside and inside of Impactor and the impactor plate using a
clean brush and a light solvent. Dry impactor parts by blowing it out
with compressed air, or let it air-dry thoroughly.
3. Apply 2 drops of oil (included) to the impactor plate. Do not over-fill
impaction plate.
