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

or after exit with .

The changes are permanently incorporated in the method only if they
are stored with

before exiting. To ensure they are also

effective for the result calculation, a recalculation must be initiated on
the "MONITORING" page with

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 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

or the

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.
