10.3.4 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
1. Click on ‘Measurement Sources’ in the Toolbox.
2. Expand the list of ‘I/O Channels’ by clicking on ‘+’ in the DDU 7 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 7 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 7.
It allows you to use a push-button.
The fixed value of the internal pullup-resistor is 3010 ohm. If using an additional external
pullup-resistor, set up the overall resistance.
