Operation
The following sections cover the basic operation.
4.1.
About the Measurement
The AEROCET 532 counts and sizes particles in 8 different size ranges then uses a
proprietary algorithm to convert count data to mass measurements (µg/m
3
). This
calculation includes a K-Factor setting that can be adjusted to compensate for local
particulate characteristics and improve measurement accuracy. The AEROCET 532
provides a separate K-Factor setting for each measurement range (PM1, PM2.5, PM4,
PM7, PM10, and TSP). These K-Factors can be modified on the K Factor screen as
discussed in section 5.3.3, with serial commands, or with Comet software.
K-Factor values should be empirically derived via comparison with a reference unit.
Refer to Section 5.3.3.
4.2.
Power Up
AEROCET 532 power is controlled by a slide switch located on the left hand side of the
unit. Move the power switch to the on position (towards the top of the case) to power up
the unit.
The first screen shown on power up is the Startup screen. This screen briefly displays
the company logo before loading the Operate Screen.
4.3.
Operate Screen
The Operate screen displays the count or mass measurement. It is determined by the
Measure
setting. The Operate screen displays the sample status, date and time,
battery status, sample data, location, temperature, and relative humidity. Figure 4 and
Figure 5 show the Mass and Count screens. Four size channels are displayed. Rotate
the dial to display additional sizes and the location.
