Analog inputs are calibrated. Measurement accuracy at inputs is 0,1.

Configuration list helps you set up analog inputs correctly. You get the configuration list together with the module SM2-AD.




A customer specifies in his order measurement range for particular inputs (e.g. 0-20 mV).

In case that measurement range has not been specified, all analog inputs SM2-AD are configured in measurement range 0-10V.







We can convert the range for measuring e.g wind speed easily. Let's suppose that 0 m/s = 0 mV and 30 m/s = 15 mV, we have to convert these values into the measurement range:

„maximum measurement range value“
————————————————— * „value representing maximum of measurement range“
„maximum measured range value“


In our example (with AI3, measurement range 0-20 mV):
20
— * 30 = 40 m/s
15

Enter the result as maximum range value and select the unit displayed with this sensor. Then measured values appear among other sensors.
