FEATURE DESCRIPTION
Root Data file
directory
(text entry field)
Defines the root directory to use when creating new DUT based
sub-directories and copying Data Files. The selected directory can be on a
network or on an internal hard drive. Any directory selection can be used
provided there is enough room to store test Data Files and that the location
is not write protected. Use the
<Browse>
button next to the entry field to
select a new or existing directory using a directory browsing tool.
Major Data File

&
Minor Data File
sub directory

(drop down list box)
FPG Tools generates default file names for Data Files (*.dat) it creates
when a test is run. It also creates and uses default directories for the Data
Files based on the DUT Definition on which the test was run. These DUT
dependent data directories are created as sub directories of the
<Root Data
File directory>
. This feature automatically sorts Data Files in DUT
dependent directories so that they can easily be retrieved when desired.
The
<Major directory…>
option determines the name of a sub directory in
the
<Root Data File directory>
. The
<Minor directory..>
determines the
name of a directory to create in the
<Major directory…>
. The choices are
DUT serial number, identification, model, manufacturer or record label.
In addition,
<None>
can be selected. The directory name will include the
full text of the DUT Definition field selected unless the
<long file name…>
option is disabled or DUT information contains one of the following invalid
characters as part of the field: /, \, ?, :, *, <, >, |, or “. If so, the directory
name will contain all text up to the first occurrence of the character.
6.6.3 [FPG CALIBRATION SETUP]
FPG specific calibration information can be selected and entered using this option. Each
FPG has it’s own unique set of calibration values that must be entered into FPG Tools to
accurately determine the final FPG pressure. This is the most critical step in the process of
the initial configuration of FPG Tools. Default values in all other aspects of the program
setup will not effect the metrology of the system.
Make sure all data is entered in the proper units with the correct sign. Failure to
accurately enter FPG calibration information will result in invalid data.
Although most users will have only 1 FPG to set up, FPG Tools supports multiple FPG
calibration records. Use the
<Display Selector>
at the top of the screen to view calibration
information from other records. To edit a file, click the desired field and make the
necessary changes. When all edits are complete either choose
[Save]
to simply store
the edits. Or choose
[Save as system selection]
to activate this record for use when the
software enters a run mode. The active system selection always displays the
<Record
Increment>
in yellow. Use the
[Add]
feature to create a new data record or use the
[Remove]
features to remove the currently selected data record.
FPG Calibration records cannot be modified when FPG Tools is in a run mode. The ability
to change and view FPG calibration information is restricted in the standard user level.
The following table summarizes the features of the
<Calibration Setup Screen>
. Refer to
the calculation section for more information on the use of these parameters.
