Tuning the valve characteristic
You can tune the valve characteristic with the graphic cursor as follows:
● You can use the softkeys to select the range of the characteristic that you want to tune,
e.g. positive zero range. The selected range is highlighted in orange in the value field.
● Cursor keys LEFT, RIGHT, DOWN and UP to move the graphic cursor in the diagram.
When the cursor reaches the edge of the diagram enlarged with "Zoom", the displayed
area of the diagram is shifted. You can move the cursor until the maximum/minimum
coordinates are reached.
● You can shift the characteristic with the graphic cursor.
● By pressing the ENTER key, you transfer the pair of values of the cursor coordinates to
the line highlighted in orange.
You cannot set the size of the rounding area at the transition between two curve sections
(rnd) using the graphic cursor. To do this, you must return to the numerical tuning and enter
the values there.
