Hum-C sensor

I barly install a hum-c sensor and i used the 4-20 output signal and i set farinhaits. Does the output readings soppust to be the same as the display.
Beside there’s another config. And says internal or external. I already make the min and max scale what the data sheet says -22 158f

Well in this picture was C but i was making the test
I try the bacnet integration and works awsome but i disconnected cause i still need the output signal we wanted like that.

The analog signals are left over from the early days of this product. it’s far better to use the digital signal for the very reason you just mentioned. there’s always a small difference between the analog signal and the digital version on the display. It’s difficult to make them match exactly due to inaccuracies in the sensor and the controller doing the sensing.
