2-10 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
Installing the Model 3077/3077A Neutralizer
W A R N I N G
The Model 3077/3077A Neutralizer contains radioactive material that is
subject to the regulations of the U.S. Nuclear Regulatory Commission
as well as local regulations. Carefully read the Model 3077 Neutralizer
operating manual to determine your legal responsibilities when using
this instrument.
C a u t i o n
When installed, the neutralizer completes a flow path inside the
classifier. If you operate the classifier with an external neutralizer or
without any neutralizer, the provided impactors cannot be used, and
aerosol flow rate cannot be measured by the classifier.
C a u t i o n
A neutralizer with sufficient charging efficiency must be installed
upstream of the DMA to give accurate results. Neutralizer age,
neutralizer activity level, aerosol flow rate, and aerosol concentration
should be considered. Contact TSI if you are unsure if your neutralizer
has sufficient charging efficiency for your application.
To install the Model 3077/3077A Neutralizer, follow these instructions:
1. If the flag assembly has already been removed, continue with step 3. If
the flag assembly has not been removed, using a Phillips-head
screwdriver, remove the two screws securing the flag assembly and
save for reuse.
2. Lift out the flag assembly by placing your fingers in the depressions on
either side and pulling up on the Polydisperse Flow outlet port.
