ariffu Sep 16, 2011 02:55 AM

Dear,

I used CR1000 data logger to reading PTB110 (CS106)barometer, but the pressure value is change very fast (not stable) ie:
1011.6 mbar (1s)
1011.4 mbar (2s)
1010.8 mbar (3s)
1011.7 mbar (4s)
etc

Could you help to fix it.

We need more details of the instruction you are using and also if you are switching the power to the sensor (if so how).

Also where is the sensor installed and how is it vented.

Hi ariffu

I think that I set the time in Scan function (1, sec).

So, you should set again this time.

I have the program for pressure sensor, It work ok.

Please download it to reference.
