I have a humidity sensor with me but I have problems with connection, both to the channel and also the Delogger. I have connected the Yellow (Temperature) to the +, the Brown (Humidity) to the - and the red to the # terminals, which I am not sure am I doing the correct thing.
The power supply that I am using gives 12V of output. At the Delogger, I choose 10V for 'sensor power supply' at the 'parameter' tab and as for 'scaling' (S1) i choose physical coefficient 1= 0; physical coefficient 2= 100; signal coefficient 1= 0; signal coefficient 2= 1000; Text= %RH.
Then at tab 'A' I have chosen S1 for scaling and labelled as RH What I got in the 'Text' window is 0.8xxx and no text label (%RH) was shown. I tried to cover the sensor with my hand and the reading seem unchanged which is impossible. Also, not sure the figure is mV or %.
Please advise, many thanks!
