This chapter is written for a service technician with skill in both electronics
and mechanics. Static preventative measures should be observed when
handling any printed circuit board connectors.
The Model 3090 Engine Exhaust Particle Sizer
™ (EEPS™) spectrometer is
designed for many hours of maintenance-free operation. This chapter
describes basic care of the instrument, some troubleshooting suggestions,
and provides information on where to go for service.
The Model 3090 is a complex instrument. Feel free to contact TSI prior to
any maintenance procedure or for general questions regarding engine
emission sampling. Read through the entire section and make sure all the
tools necessary are available before starting to disassemble the instrument.

Table 6-1 provides a general indication of the maintenance requirements. In
applications where high concentrations may be generated, maintenance is
required more often.

In general, if the instrument is functioning properly (sizing particles
correctly compared to a standard, and without excessive noise),
cleaning is not recommended
—it can lead to leaks or damage if not
done correctly.
