DMS 2 Operating Manual
DELETE ACTIVE — Deletes only the active data file
DELETE ALL — Deletes all data files
Step 5: A prompt will appear asking you to press and hold
to confirm the deletion of the file(s).
Step 6: The active data file (or all files) will be deleted when
the DELETE command is confirmed. These files are no longer
stored in the instrument and MAY NOT BE RETRIEVED .
5.2
Navigating in the Data Recorder Mode
Once thickness measurements are stored in data files, users
can quickly locate specific points within a file and search for all
thickness measurements with a specific attribute. For instance,
using the SEARCH operation, a user can retrieve only those
thickness readings that violate the active data file’s minimum
thickness limit. This section of Chapter 5 describes the several
ways you can navigate in the DR Mode. These include moving
•
From one data file to another
•
To a specific data point in file
•
To data points with features that have been identified or
“tagged”
You’ll also learn how to modify the instrument’s built-in
Automatic Navigation and Data-point Advance features. The
appearance of the DR display screen can also be modified with
the VIEW selection (Section 5.2.6) found in the RECORD
submenu. Finally, you’ll learn how to view stored A-scans and
B-scans (Section 5.2.7).
5.2.1
Changing the Active Data File
Push
below the FILE selection (found in most DR and
some TG Submenus) to page through the list of available data
files. The data file that’s highlighted (in the File List portion of
the display screen), will become the active file. Data contained
in the active file will automatically be displayed in the File
Navigation Window and other file attributes will appear on the
display screen.
Note that at any time, the active file may be set to NO ACTIVE
FILE, which means that no stored thickness measurements will
be displayed. At this point the File Navigation Window will be
blank. When no data file is active, the size of the displayed
thickness measurement increases to .750 in. high digits (known
as the BIG DIGITS Mode).
