Modify
column
Modify baseline parameters column-by-column
Modification of the parameters for calculation of the baseline (not
possible for curves recorded with PSAMODE). For details of the
baseline parameters, see section 5.6.3.
Modifications made here initiate a recalculation and baseline display
on closure of the entry. These changes are temporary, they are
canceled with
<Reset param.> or after exit with <ESC>.
The changes are permanently incorporated in the method only if they
are stored with
<Save param.> before exiting. To ensure they are also
effective for the result calculation, a recalculation must be initiated on
the "MONITORING" page with
<Recalc. from proc.> .
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 cur-
sor 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.
