Maintenance
The S
IDE
P
AK
™
SP330 and SP350 require periodic maintenance. The most
common procedures are listed below:
•
Charging NiMH batteries
•
Cyclone maintenance
•
Sorbent Tube Holder maintenance
•
U-Tube and Luer Adapter maintenance
•
Changing the pump inlet filters
In addition to the procedures in this chapter, TSI recommends that you
return your S
IDE
P
AK
™
Model SP330 or SP350 to the factory for annual
service. Regular factory-authorized cleaning and testing helps ensure that
your instrument is working properly, has the latest updates, and will provide
accurate and reliable measurements.
Maintaining Rechargeable Battery Packs
The S
IDE
P
AK
™
SP330 and SP350 Personal Sampling Pumps incorporate the
Smart Battery Management System
™
technology that allows for fast
charging and long battery life. This system utilizes a built-in computer chip
in the battery packs. The microprocessor monitors battery capacity and
calculates run time information by dividing capacity of the battery (mAH)
by the instantaneous current consumed by the instrument (mA). This
calculation is correct for current operating conditions and can change due to
current (mA) consumption or changes in battery capacity. Conventional
battery controllers can only make crude estimates of battery condition based
on a simple voltage measurement.
TSI rechargeable battery packs use nickel-metal hydride (NiMH) cells
because they provide much greater capacity than conventional nickel-
cadmium (NiCad) cells and do not have the “memory” problems often
associated with NiCad cells.
Charging a NiMH Battery Pack
The power supply allows you to power the S
IDE
P
AK
™
SP330 and
SP350 Personal Sampling Pumps from an AC outlet, or to charge any of
the TSI NiMH battery packs. The S
IDE
P
AK
™
has internal charging
circuitry. Connect the power supply to an AC outlet and plug the other
end into the power port on the side of the S
IDE
P
AK
™
SP330 or SP350.
