Example 3. When a portion of the linked files does not exist and the search period
includes that portion
File A File B
File C
Missing
File D File E
Search period
Files B and D, which overlap the search period, are displayed on the file view tabbed page.
If the files are linked, the unit consisting of files A and B and the unit consisting of files D
and E are displayed on the link view tabbed page. In the case of a batch file, files A to E are
detected as a single unit and displayed on the link view tabbed page.
Example 4. If the time was changed in the middle of recording
File A File B File C File D File E
File A File B File C File D File E
If the time on the recorder was changed during recording, the timestamps of data entries are
calculated in reference to the last data entry position. As shown above, if the time is changed
from 6:00:00 to 10:00:00, the original timestamps from 4:00:00 to 6:00:00 are assumed to
be 8:00:00 to 10:00:00. These timestamps are used in the search, so if you set the search
period as 5:00:00 to 6:00:00, nothing will be detected. If you set the search period as
8:00:00 to 9:00:00, files will be detected and displayed on the link view tabbed page.
Searching by Channel Number, Tag Number, or Tag Comment
From the list box, select Channel No., Tag No., or Tag Comment, and then enter the
character string you want to search for. Data files that contain the string will be displayed in
the search results.
You cannot specify a character string that includes a space.
Searching by Batch Name
Select the Batch Name check box, and enter the batch number and lot number.
You can also search by specifying only the batch number or only the lot number. If you
select the check box and leave both the batch number and lot number blank, data files that
include batch information will be displayed in the search results.
Searching by Signin Status
Of the data files that include signature information, data files with the selected signin
statuses are searched. From the list, select the signin status you want to search for.
The available options and their descriptions are shown below.

3No sig. Files without Signature 3

conditions are detected.
