3.25.5 Zoom Mode This is used for horizontal expansion of the actual measurement displayed
(ZOOM) to observe the measurement with better definition. When the
ZOOM function is on, the
Marker function is enabled as well. A small blue
triangle appears on the display and can be moved with the mouse to any
point on the graph. The window at the bottom will show the amplitude
marked and the time of occurrence.
To enable the
Zoom function proceed as follows:
•
select the Zoom Mode key;
•
position the mouse on the Marker triangle at the starting point;
•
holding the left mouse key down, drag the Marker to the point at
the end of the trace you wish to expand. Release the mouse key
and the selected trace will be expanded immediately.
During this operation an orange cross and two vertical bars are displayed to
aid in selection of the area to expand. To return to normal display unselect
Zoom Mode .
The smallest selectable trace is 120 seconds (2 minutes). A greater
enlargement would only put more space between the two
measurement points without adding any significant information.
If you try to zoom on a trace of less than 2 minutes an error message will
be displayed.
As already mentioned, the Zoom Mode key is used to enable the Marker ,
represented by a colored arrow which, using the mouse, can be positioned
anywhere along the displayed trace. In this case, the time values will be
reported on the status bar at the bottom of the screen (time from start of
measurement) and the amplitude will be displayed with respect to the
actual position of the
Marker . This function is used for a detailed analysis of
the graph and of the relative values saved.
When the Zoom Mode key is enabled, the other commands are
automatically disabled except Save, ClipBoard and Help.
