I have a CR1000X and a CS106. I get readings with +-1 hPa variations in less than 1 minute. Is this normal? What could be the cause?
ShortCut suggests the following code for the CS106 on a CR1000X. Try this code and see if it improves things for you :
The C1 line is used to enable the CS106, if the jumper inside the CS106 has this set. Check the CS106 manula for detailsof the enable line.
50Hz rejection (50) may need to be changed to 60 if where you are has 60Hz mains.
