Operate Screen
The Operate screen can display the count or mass measurement. It is determined by
the
MEASURE
setting. The Operate screen displays the date and time, sample status,
current sample data and previous sample data. Figure 5 and Figure 6 shows the Mass
and Count screens.
When sampling in mass mode, the size selection represents the upper threshold of your
sample. For example, when you read the value for PM10 it contains all mass that is
size PM10 and lower. Conversely, when sampling in count mode, the size selections
represent the lower threshold of your sample. An example would be that the 1.0
µ
m
size contains all particulate that are 1.0
µ
m and larger.

– Count Operate Screen with AT and RH
The top line of the Operate screen is reserved for the normal header (date and time) or
status/alarm messages depending upon the machine status. The top line remains
stationary while the other 3 lines scroll to display the full list. AT and RH data will
precede the location number when the AT/RH probe is attached.
Ambient temperature (AT) can be displayed in units of Celsius (C) or Fahrenheit (F).
