Start

zoom

Select zoom range

This softkey starts the selection of the zoom region (curve section
which should be enlarged).

A segment curve can be zoomed only in the y direction,

the x axis is always shown full scale (limit values

U.start

and

U.end

of the segment).

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 key is pressed at the same time. In
both cases, the cursor keys are repetitive, i.e. the longer the cur-
sor key is pressed, the further the corner point is shifted.
