CEL-712 Microdust Pro Real-time Dust Monitor
38 Casella Measurement
You can make measurements with the probe clipped to the instrument,
or you can unclip the probe to allow easy access to confined spaces.
3. Make the required measurements for the application (refer to
Measurement types below).
4.1 Measurement types
In addition to the basic real-time measurements of particulate concentration,
the instrument can also calculate and display other useful data.
Maximum value (Max)
This represents the maximum particulate concentration that occurred in any
1 second period since the measurement Run was started.
You cannot reset the maximum value whilst a Run is in progress.
Average (Avg)
The average value represents the average particulate concentration since the
measurement Run was started.
You cannot reset the Average whilst a Run is in progress.
4.2 Starting a measurement Run
The data logging configuration is set using the Measurement Settings
screen. See Data logging options on page 22 for an explanation and for
instructions to use this screen and the available options.
Starting a Run
If necessary, follow the instructions in section 4.4 Deleting stored Runs on page
42 to clear space in the instrument’s internal memory before you start logging
measurements. This is important, because data logging stops automatically
when the memory becomes full.
Press the Run/Stop key from a measurement screen with the instrument
in Stop mode to begin logging data. See the example in Figure 19.
The instrument displays a measurement screen that has green bars at the top
and bottom when a Run is in progress.
