Select the input from the drop down list.
In our example below, we will create a new scaled pressure sensor output that can be used to drive a gauge on the
dash. It will use the Analog 3 input from the 30-2206 on Pin 7. Three things are required. 1.) You must create a
new Output Name. 2.) You must add an Operation to scale the voltage into pressure units. 3.) You must define a
Primary Input. First create the new Output Name. We will use
My Pressure .
For this example, let's assume that the sensor is a typical 0-5V analog sensor that is calibrated as follows: 0.5 volts
= 0 psi and 4.5 volts = 100 psi. Consult your sensor documentation for proper calibration values. There are several
options but the easiest method is to use a Function table. Lets create a new Function to define this calibration.
In the Functions tab, create a new Function. We will call it My Pressure Sensor Function; Volts to PSI. It will
convert voltage to PSI.
Click on the (...) symbol to define the function table. Enter the data as shown below to create the calibration curve.
