4.17 Editing the valve characteristic
Incomplete measurement
The "End point" softkey is only active for an incomplete measurement if this was planned as
complete measurement (up to 100 %). The measurement cannot be performed completely if
the piston cannot be accelerated to the end velocity because the measurement path is too
short.
The graphic cursor can only be moved vertically at U = ±100% when the "End point" curve
range is selected.
● In the positive range, the cursor movement changes the controlled system gain. The
value of the plane adaptation remains at 100%.
● In the negative range, the cursor movement changes the negative plane adaptation. The
value of the controlled system gain remains constant.
If the cursor is moved up or down out of the display area, the zoom factor of the diagram is
adapted dynamically. If the cursor exceeds 200% on the Q axis, an appropriate message is
issued. You must change the controlled system gain.
Further actions
Use the softkeys to select the pair of values that you want to change.
● Use the "Positive range" softkey to select the positive range of the valve characteristic
(first quadrant of the coordinate system).
● Uses the "Negative range" softkey to select the negative range of the valve characteristic
(third quadrant of the coordinate system).
● Use the "Zero range" softkey to select the zero range of the valve characteristic.
● Use the "Transition range" softkey to select the transition range of the valve
characteristic.
● Use the "Saturation range" softkey to select the saturation range of the valve
characteristic.
● Is the "End point" softkey to change the controlled system gain and the plane adaptation.
The "End point" softkey is only active for an incomplete characteristic measurement.
● Use the "Back" softkey to return to the numeric input mode.
