Softkeys Meaning
Start
zoom
Select zoom range
This softkey starts the selection of the zoom region (curve section
which should be enlarged).
First, the cursor keys <è>, <ç>, <é> and <ê> must be used
to define the top left corner point of the zoom region (marked by a
cross) as follows:
Each time these keys are pressed, the corner point moves
in the selected direction by 5 pixels. A finer shift of 1 pixel
can be achieved when the <SHIFT> key is pressed at the
same time. In both cases, the cursor keys are repetitive, i.e.
the longer the cursor key is pressed, the further the corner
point is shifted.
Uppr/lft
corner
Once the top left corner point is in the desired position, it must be
fixed by pressing the softkey <Uppr/lft corner> or the <ENTER>
key. Next, the bottom right corner point of the zoom region is also
defined using the cursor keys. This automatically opens a frame
encompassing the region to be enlarged.
Lwr/rght
corner
Once the bottom right corner point is in the desired position, it must
be fixed by pressing the softkey <Lwr/rght corner> or the
<ENTER> key. The selected zoom region is then shown full screen.
The procedure described for selection of the zoom region can be
repeated several times in succession. The enlarged curve display
remains active until the spike elimination is exited by pressing the
<ESC> key.
