3.2.5.5 Transient Windows
Transient windows are those that appear momentarily. They pop
up over any existing window to inform the user of a problem
or of a background task being completed. They require a user
response, normally pressing the “OK?” button, to acknowledge
the message.
3.3 Browsing, Compressing and Searching Data
Once at the full trend screen (using the VIEW button), the user can choose to browse, search or compress either
data from the disk, including the file currently being recorded to disk, or immediate past data which is buffered to
memory (RAM). The operation of browsing is the same whether the user is browsing memory or file data. When
BROWS is pressed a new button bar is presented with three buttons, FILE , RAM and EXIT as shown in Figure 3-
9 below.
Select FILE to browse prerecorded files on the disk, RAM to browse Trend data from memory, or EXIT to return to
the real time view.
Browsing allows the user to view historic data of the pens currently trending on the display or saved on the disk,
without affecting any real time data acquisition. Alarm data can also be browsed from memory by selecting BROWS
on the full view Alarm window. See section 3.3.5 for the added step required to browse from disk.
On the Trend screen, pressing BROWS brings up the Browse Source button bar. Press RAM to browse memory or
FILE to browse from disk. This brings up the Browse Mode Button Bar shown below (Figure 3-10).
The FINDV and the FINDT buttons initiate the SEARCH functions. FINDV is FIND by Value, FINDT is to FIND by
Time. The “
ÎÍ“ and “ÍΔ are to COMPRESS and EXPAND data respectively. BROWS enters the interac-
tive Browse Screen and EXIT returns to the prior screen.
3.3.1 Compressing Data
The data on the screen may be compressed up to 32 times the normal view, this enables long term trends to
be seen on a single screen. Each time the “
ÎÍ“ (Compress) button is pressed the data is compressed by a
factor of 2, and it may require a short time for the recorder to process the data. Five presses give the maximum
32 times compression. The data may be expanded back by pressing the “
ÍΔ (Expand) button. The user can
enter the interactive browse mode with any level of compression by simply pressing the BROWS button.
