Display Count Mode
There are three display modes for particle counts: Cumulative (CUMU), Differential
(DIFF), and Concentration (e.g., Counts per Liter). The factory default setting is
cumulative.
Count Mode Meanings
Cumulative
The results represent the number of particles that are larger than
the size (channel) that is displayed.
Differential
The results represent the number of particles between the size
(channel) that is displayed and the adjacent channel (the larger
size). The number displayed does not include the particles
whose sizes are larger than the adjacent channel or larger.
Concentration
The results represent the number of particles in a unit volume
under the accumulative situation. The unit volume may be set
Counts per Liter, Counts per Cubic Meter (Counts/ Cu.M.), or
Counts per Cubic Foot (Counts/Cu.Ft.).
Sample Time (SampTime)
Sample time is the time that is set for each air sample. Sample times can be set as low
as one sample per second. In the case of multiple air samplings, each air sample will run
at this sample time setting.
Number (No.)
Number indicates the number of samples that will be processed after pressing, “RUN”.
The factory default is set at one sample. The user may change the sample time in the
Setting window. In the case that “No.” is set at more than one sample, the displayed
result is the average of the multiple samples.
Location
Location allows the user to label a location for each measurement by selecting a letter
from A to Z. The location can only be changed in the Setup window.
