Description
NORMAL
Displays cumulative counts on the screen and in reports.
DIFFERENCE
Displays differential counts on the screen and in reports.
The Normal mode displays cumulative counts. For a given size the counts represent all
particles that size and larger.
The Differential mode displays the number of particles between a given size and the
size larger. When in differential mode, the volume units will be preceded the delta
character
Δ
on the screen. For the serial output a
lower case ‘d’ character is displayed
in the header.

Recall Data Screen
Stored sample events can be viewed from the Operate Screen but this requires
navigating one record at a time to reach a desired record. The Recall Data Screen
provides a way to quickly navigate to a record based on time. Figure 15 shows the
Recall Data Screen.
