5-24 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
Hardware Tab
In typical usage of an SMPS 3938 spectrometer, the peripheral hardware
(detector, DMA, impactor, neutralizer) is auto-recognized. However, in
some situations, an override of the default configuration may be required.
The Hardware tab allows you to override these as necessary.
To set the peripheral hardware configuration, follow these instructions:
1. Touch the Hardware tab on the Properties screen.

2. Touch the DMA drop-down field and select an option from the list. You
can use this option if your Model 3081 or 3085 DMA has not yet been
upgraded for auto-recognition.
The DMA voltage supply polarity is noted as either Neg (negative, TSI
Model 308200) or Neg/Pos (negative and positive, TSI Model 308202).
Notes: If the system recognizes the installed DMA, you will not be able
to override the setting.
You can enter settings for a custom DMA through a terminal
emulation program (see Setting Up a Custom DMA).
3. Touch the Impactor drop-down field and select an option from the list
(0.0457, 0.0508, and 0.0710 impactors). This is a useful option if the
auto-recognition feature of the impactor is not functional, or if a 3080-
style impactor of the same orifice size is being used. When the
impactor is selected, the classifier uses a default calibration curve to
calculate aerosol flow rate.
Note: If the system recognizes the installed impactor, you will not be
able to override the setting.
4. Touch the Neutralizer drop-down field and select an option from the
list. This is useful if the neutralizer is being run external to the classifier.
