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.

calculate and display other useful data values as follows.
