Micro-PWC OPERATOR’S MANUAL
74 Using Graphic Displays
7.5 Alarm Acknowledgment
A graphic can allow alarm acknowledgment. For example, a graphic can be configured so that a pushbut-
ton labelled ACK appears when a point in alarm needs acknowledgment. Click the pushbutton to acknowl-
edge the alarm and remove the pushbutton from the display. Note that this is a user-configurable option; if
you have questions on how graphics have been configured on your system, consult your system adminis-
trator.
Alarms can also be acknowledged from a graphic by pressing
A LT -F10 on the keyboard, or by selecting
Window > Acknowledge from the Operator Window menu bar. Each point which needs acknowledgment,
and whose ACK atom is referenced by the graphic, is acknowledged.
7.6 The Zoom Menu Item
By default, the entire Graphic Display is always shown in the Operator Window when the graphic is first
called up.
The Zoom item on the menu bar of the graphic display provides access to the Zoom and Pan operations,
which are used to change:
• The portion of the Graphic which is visible in the Operator Window (Pan).
• The amount of the Graphic Display which can be visible in the Operator Window, known as the
view size (Zoom).
The view size always has an Aspect Ratio 4 (wide) by 3 (high), to maintain correct proportions of models
during scaling operations.
To access the Zoom and Pan functions, click Zoom on the menu bar of the graphic display. The Zoom/Pan
window (
Figure 7-7 ) will be displayed.
The top portion of the Zoom/Pan window provides PAN functions, while the bottom part of the window is
devoted to the ZOOM operation.
If the Zoom/Pan window is on display and the display in the Operator Window is changed to any type of
display other than another Graphic or a Trend, Group or Point display, the Zoom/Pan window will automat-
ically be closed.
