Maintenance
The SidePak Personal Aerosol Monitor Model AM510 requires
periodic maintenance. The most common procedures are listed
below:

Charging batteries

Zeroing

Impactor maintenance

Cyclone maintenance
In addition to the procedures in this chapter, TSI recommends that
you return your SidePak
Model AM510 Personal Aerosol Monitor to
the factory for annual calibration. Regular factory-authorized cleaning
and recalibration helps ensure that your instrument is working
properly, has the latest updates, and will provide accurate and
reliable measurements.
Maintaining Rechargeable Battery Packs
The SidePak monitors 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 SidePak monitor from
an AC wall outlet, or to charge any of the TSI NiMH battery
packs. Connect the power supply/charger to an AC wall outlet
and plug the other end into the power port on the side of the
AM510.
