Section 5:    DISPLAY OF GRID PARAMETERS

5.1  Display of 3 selected grid parameters

In Auto-Mode, button 

é

 leads to display mode 1. Here 3 (free selectable) grid parameters 

are displayed in large letters. The selection and storage of these values is done in the 
Display- Editor.

Example:  Display mode 1:

Desired values selected in the
Display Editor (see section 13 )

5.2 Display of particular grid parameters (from AUTO-MODE by pressing ENTER)

By  repeated  activation  of  the  “ENTER”-button  (in  automatic  operation)  several  grid 
parameters can be displayed (s. table below):
