Chapter 2 - Using the Microdust 880
Preparation for use
The general instrument layout is shown below:-
The Microdust is a sensitive scientific instrument which should not be exposed to excessive
moisture, vibration, or physical shocks.
We will now take a few moments to look at the steps which must be performed before the Microdust
can be used under operating conditions.
Battery charging
The Microdust is powered by a rechargeable nickel-cadmium battery pack which is charged using the
charging socket located at the top of the instrument. When the optional leather case is used, unclip
the protective flap and insert the charger plug. It will take approximately 12 to 14 hours to fully
charge the battery.
To facilitate continuous sampling, the instrument can be run for extended periods directly from the
mains charger. For Intrinsically safe instruments, this only applies in an uncontrolled area.
