Hello In my case I think it's not a rf problem. I am far away from rf or cell phone stations and the shack is well protected against rf from outside and no cell phone nor other transmitters were used in this room at this time. If it would be an emc problem - why is only the temperature output affected? I rather believe it is an internal digitizing problem, this chip is specified to work with 0.5 deg. C steps, if I am not wrong, and the higher resolution is achieved by a programming trick.
