Chapter 3 Getting Started
Page 3-3
3.1.2 Button Bar
The
Button Bar
, located on the bottom of the screen, contains “buttons” used to operate the unit. When the
unit is powered up, the
Main Button Bar
is shown (see Figure 3-3). The
Main Button Bar
has four buttons:
VIEW
,
BROWS
,
JOG
and
MENU
. The date and time are continuously displayed in the middle of the
Main
Button Bar
. The date is shown numerically in either American (Month/Day/Year) or (European Day/Month/
Year) format. Refer to Section 5.4.2 to program the date format.

3.1.2.1 VIEW Button
The
VIEW
button enables the user to scroll through the selectable display options in the
Graphics Area
of the screen (see Section 5.4.7). These views might be charts, bar graphs, digital windows, alarm/event
information or combinations of these. Each time the
VIEW
button is pressed, the next view is presented.
3.1.2.2 BROWSE Button
The
BROWS
e button is only displayed on screen views that can actually be browsed, which are the full
screen Trend Chart Window and the full screen Alarm/Event Data Window. The user can choose to browse
RAM
(Random Access Memory) which is the screen trace data, or
FILE
, in which case a file menu will be
presented so that the user can choose a file from the disk/card. The
BROWS
e button also allows the user
to
SEARCH
historic data by
VALUE
or
TIME
, as well as
COMPRESS
data in time.
Pressing the
BROWS
e button puts a freeze on the real time display and allows the user to scroll back in
time to browse through historical data that has passed off the screen or has been recorded previously, even
on another machine. The actual Chart screen browse buffer is dependent on the memory options installed,
the number of traces being displayed and the effective Chart speed. With the standard buffer, a Chart
speed of one inch per hour with four traces active, it is possible to browse back approximately 140 hours
(5½ days). The user may choose to browse files on the disk/card rather than the current memory buffer even
though the unit is currently recording. The user can then browse files that had been recorded earlier, or may
even browse the file that is currently being recorded. Once the data has been recorded to disk/card, it is
possible to use the file browser or the PC and the optional
Companion Software
to view data as far back as the
start of recording, irrespective of how long that may be, within the constraints of disk/card capacity.
3.1.2.3 JOG Button
The
JOG
button is used to switch between channel data. At any time the user can press the
JOG
button to display point data in the
Status Line
. Each time the
JOG
button is pressed the next point
data is displayed.
3.1.2.4 MENU Button
When the
MENU
Button is pressed, the
Command Menu Button Bar
appears (see Figure 3-4) allowing
the user to change
DISPL
ay features,
PROG
ram the unit and set
FUNC
tions. Refer to Chapters 4 and 5
for details.
Figure 3-4 The Command Menu Button Bar
The
Button Bar
will change depending on the mode and the buttons pressed. Certain key buttons will always
be displayed in the same place, such as the
ENTER
Button on the left and the
EXIT
button on the right,
allowing rapid movement through menus.
