Configuring a multipoint adjustment
Example: Measurement of wheel force
▪ Physical property 'wheel force' not directly measureable
▪ Load transfer through suspension kinematics
▪ Physical value at sensor position defined by vehicle
▪ Curve definition by online adjustment at vehicle
Force at wheel
1. Click on 'Measurement Sources' in the Toolbox.
2. Expand the list of 'I/O Channels' by clicking on '+' in the DDU 8 Project Tree.
3. Drag the 'Multipoint Adjustment' analog signal source from the Toolbox and
drop it on the desired analog input channel in the DDU 8 Project Tree.
4. A 'Multipoint Adjustment Wizard' opens.
5. To activate the internal pullup‐resistor, check the box.
The internal pullup‐resistor is used to get a 5 V signal at the analog channel
of the DDU 8.
It allows you to use a push‐button.
The fixed value of the internal pullup‐resistor is 3010 ohm. If using an addi‐
tional external pullup‐resistor, set up the overall resistance.
