This chapter describes how to operate the Model 3082 Electrostatic
Classifier using the touch-screen display. Touch the screen with your
fingers or the supplied stylus to make selections. For instructions on how to
operate the classifier using Aerosol Instrument Manager software, refer to
the Aerosol Instrument Manager
®
Software for SMPS™ Instruction Manual
(TSI P/N 1930038).
Operat i n g Precau t i o ns
Before applying power, review the operating specifications for the
Electrostatic Classifier described in Appendix A.
When using the classifier, follow these operating precautions:
High-voltage is accessible within this instrument. Unplug the power
source before removing the cover to perform maintenance procedures.
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.
The Model 3088 Advanced Aerosol Neutralizer contains an x-ray
source, which may be subject to local regulations. During normal
operation, you will not be exposed to x-ray radiation. Do not make any
changes, such as detaching the x-ray source from the neutralizer tube,
to the Aerosol Neutralizer.
Install the Neutralizer as described in Chapter 2, Unpacking and
Setting Up the Electrostatic Classifier.
If you operate the classifier without a Model 3077/3077A or 3088
Neutralizer (such as for electrospray applications), do not use the
aerosol inlet. If you do, you are not completing the aerosol flow path.
Instead, remove the flag assembly and connect the aerosol source
directly to the DMA polydisperse inlet.
Do not operate the classifier without the impaction plate installed. If
you do, the penetration curve will be incorrect and the aerosol flow rate
cannot be measured. A “Low aerosol flow” warning may indicate the
absence of an impaction plate.
Never use the DMA as a handle when lifting the classifier.
