The bin settings to be used in the CCN-200 concentration calculations. The bin settings are
typically zero. If they are non-zero, they act as a filter for particle concentration calculations,
which factor in counts from the “Bin Setting” bin upwards.
•
The set total flow (this must be a single value for any given table, i.e., it cannot change with
supersaturation changes)
# of SS Settings allows the user to determine how many SS settings will be stored in a given table.
This number determines the number of active rows in the
SS Table
.
Index
lists the row number of the first row displayed. Rows start at 0. Changing the index will allow
you easily to view rows farther down in the table. You can also use the scrollbar to the right of the
table to navigate up and down.
Once the table has been configured, click on
Save
to save this table to the current configuration file.
Then move on to the next desired configuration. The fields at the bottom of the screen can be used
to copy values from one table to another in the event that two tables share a portion of data.
The
Start Delay (sec)
parameter specifies the length of the time frame during which the user can
select the
Dry Start Up
or
Dry Shut Down
options. If Start Delay (sec) is set to 30, for instance, the
user will have 30 seconds after the Dual CCN.exe program starts during which to select a dry start-up
or shut-down.
Following the configuration of all the desired tables, exit the
SS Settings Config Editor
program.

CCN Calibration Editor.exe
The
CCN Calibration Editor.exe
program allows users to set calibration coefficients that determine
equations for flows, temperature gradient, proportional valve settings and so on. The calibration
coefficients for each of these measurements are stored in a table that is accessed by the program.
These systems are calibrated before the unit leaves DMT, but it will be necessary to recalibrate them
periodically. The USB memory stick that accompanied the CCN-200 upon delivery contains
spreadsheets that are useful during calibration.
Note that many of the calibration coefficients displayed in
CCN Calibration Editor.exe
can also be
modified by using the
DMT Service
tab on the main control program,
Dual CCN.exe.
The control
program only saves these changes if the
Save
button is pressed. In contrast, the calibration editor
program always saves changes and the new values will be used upon startup of the control program.
While the DMT Service tab allows the user to modify many of the parameters available on the
CCN
Calibration Editor.exe
, the Calibration Editor program provides access to some unique parameters
as well.
