7. Enter the mass of the sample; 1.0000 gram, ± 0.05 (determined to nearest 0.0001 gram) is the
recommended amount of sample to use.
8. Edit the
Skeletal
and
Bulk
densities if needed.
9. Choose the type of sample material you are analyzing. The Material type is used to
determine which carbon property models are used for this particular carbon. For example, a
different equation is used to predict COAN for Tread/Hard carbons than for Carcass/Soft
carbons. If you select
Other
, the COAN is not
calculated.
10. Click
Save
, then
Close
.
Creating Parameter Files
The following file types exist as part of the sample information file or as an individual parameter
file:
• Analysis conditions, page
3-10
• Report options, page
3-11
Having these files exist independently enables you to use them over and over again.
Several predefined parameter files are included with the DVVA II application. Although these
files may come close to the needs of your laboratory, you may wish to define additional ones. Or
you can use a predefined file as a starting point. This is easily accomplished by creating a new
file and then selecting
Replace
. A dialog is displayed so that you can select the existing file con-
taining the values you wish to use.
Be sure to save new parameter files to the directory specified as the Parameter Files Directory
(see
Parameter Files Directory
, page
8-19
) to have them display in the drop-down lists. Unless
you have edited the parameter files directory, the files are saved to the default PARAM directory
automatically.
You can also create parameter files from the Advanced Sample Information dialog. For example,
select
File > Save As > Analysis Conditions
to save the analysis conditions of the current sam-
ple information file as a standalone Analysis Conditions parameter file.
