2.4 Measurement
Before carrying out measurement, check the zero and span as described in
Section 2.3.1, calculate and apply a dust correction (Sections 2.3.2 and 2.3.3)
and select an Averaging Time and Range appropriate to the monitoring
application (Section 2.2.3).
With the measurement chamber aperture exposed, slowly move the probe
through the aerosol or rely on natural air movement. Measurements can be
taken with the probe either clipped to or unclipped from the display unit. For
static monitoring applications the use of an aspirator system is preferred
(refer to the Sampling Accessories sections in Chapter 4).
Any dust deposited on the surface of optical components should be blown
clear. To prolong the serviceable life of the instrument, it is recommended
that this operation be performed before and after each use.
In addition to the basic real time dust indication, the MicroDust pro is able to
calculate and display other useful data values as follows.
2.4.1 Maximum Value (Max.)
