viii Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
W A R N I N G
Although the 3938 SMPS spectrometer is appropriate for monitoring
inert process gases such as nitrogen or argon, it should not be used
with hazardous gases such as hydrogen or oxygen. Using the 3938
SMPS spectrometer with hazardous gases may cause injury to
personnel and damage to equipment.
Electr i c a l Safety
The Electrostatic Classifier Model 3082, all supported CPCs (Models 3772,
3775, 3776, 3777, 3787, 3788), and all supported DMAs (Models 3081(A),
3085(A), and 3086) have high-voltage points within their housings. Only a
qualified technician should perform service or maintenance.
W A R N I N G
High-voltage is accessible within this instrumentation. Unplug the power
source before removing the cover to perform maintenance procedures.
Do not apply power to the Model 3938 SMPS spectrometer unless the
DMA high-voltage cable is connected to the 3082 Classifier and the
base DMA is mounted to the 3082 Classifier.
Always use the provided power cord to ensure proper grounding of the
instrument.
