11.2.2 Configuring a generic linear sensor
52 / 136
Example: Acceleration sensor 5 g
– From sensor data sheet - operating characteristics:
– Sensitivity 400 mV/g, Offset 2,500 mV
– The sensor has a linear output signal with sensitivity and offset
1.
Click on 'Measurement Sources' in the Toolbox.
2.
To expand the list of 'I/O Channels', click on '+' in the Vehicle Control Unit VCU Pro-
ject Tree.
3.
Drag the "Sensitivity/Offset" analog signal source from the Toolbox and drop it on the
desired analog input channel in the Vehicle Control Unit VCU Project Tree. A "Sensit-
ivity/Offset Wizard" opens.
4.
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 Vehicle Control Unit VCU. It al-
lows you to use a push-button. The fixed value of the internal pullup-resistor is 3,010
Ohm. If using an additional external pullup-resistor, set up the overall resistance.
5.
Click 'Next' when done.
The second part of the "Sensitivity/Offset Wizard" opens.
