Particulate pump: enable or disable
You may wish to disable the particulate pump for situations in which
the environment is too dirty for the particulate optical engine or if you
want to keep the engine and pump clean and dry from oily mists,
liquids, or fogs elements. Additionally, you may want to log other
parameters, such as CO2, Toxic, and/or temperature and humidity
parameters and exclude the particulate measurements from a log
session. This is changeable in the particulate screen.

Resetting the gravimetric filter
The Gravimetric accumulators display the calculated accumulated mass
of particles and the accumulated volume through the gravimetric filter
(since the last time these accumulators were reset). At the same time,
the particles are actually collected in the gravimetric cassette in the
back of the unit. Typically the gravimetric accumulators are reset
when the gravimetric cassette is replaced by the user.
