3.13.1 File Browsing
File browsing can be done at any time, even when still recording. However, if you are browsing from disk/card
while recording, there may be delays in retrieving data from the disk/card as writing to the disk/card has priority
over reading from the disk/card.
To
Browse
a
File
:
From the Browse Source Button Bar (Figure 3-14), press the
FILE
button. The unit will check the disk/card
and then bring up the File Directory window (see below) allowing the user to choose which file to browse.
File Directory
Point 1:
→
BATCH1
.DT1
←
(Date) (Time) (Size)
BATCH2
.DT1
BATCH3
.DT1
NOTE:
Ensure that a disk/card is present and that it has suitable files or you will get an error message.
Use the
UP (
↓↓↓↓↓
)
or
DOWN (
↑↑↑↑↑
)
button to move the arrows to the file you want to browse and then press the
ENTER
button. You will enter Browse Mode and the
Browse Mode Button Bar
will appear as shown in Figure
3-15 below.
The
FINDV
button allows the user to
FIND
by
V
alue, while the
FINDT
button allows the user to
FIND
by
T
ime.
The
BROWS
button enters the Interactive Browse feature (see Section 3.13.4). The “
ÎÍ
“ and “
ÍÎ
” buttons
are to used to COMPRESS and EXPAND data respectively, and the
EXIT
button returns you back to the
File Directory window.
3.13.2 Searching Data By Value
To Search the historic data by Value:
From the Browse Mode Button Bar, press the
FINDV
(FIND Value)
button. This will bring up the
Search Value
Button Bar
as shown in Figure 3-16 below.
To set up the actual Value to search for, press the
VALUE
button. Use the numeric keypad to enter the Value
to search for. You cannot search for an exact match; you will be looking for a Value immediately greater than
or less than the Value you enter. Once you have entered the Value you want, press the
ENTER
button.
Before searching for the Value you set, you have to decide which
PEN
or point to use as the search reference
and in which direction to search.
Use the
PEN
button to select the pen trace to search. Each time this button is pressed, the next pen is
selected. The current pen is shown in the Status Line at the top of the screen, together with the value of the
trace under the cursor and its actual time and date stamp.
The File Directory will list the file(s) for each Point,
starting with Point 1. The filenames are specified
by the user at the time of recording and have an
extension of DTx where x is the Point number. The
filename list will scroll if it is longer than what will fit
on the screen. If no files are available for a particular
point, the directory will indicate “No Files Found”.
