Note
Working with automatically created measurement sheets is explained in chapter 'Setting
up an online measurement [} 73]'.
Example: Thermistor 5 kOhm
– From sensor data sheet - resistance values over temperature:
– The sensor has a nonlinear behavior
– Use characteristic curve for linearization
– Input voltage is the ratio between pull-up resistor and thermistor
+5V
