Hello!!!
I hope this is the correct place to this post!!!
I have a Testo 550 about 2.5 years.
Now the readings are constantly unstable.
Do anyone see something like this?

.

Transducers self calibrate in atmospheric air pressure.
Check that the sensor is not blocked at the connection point and check the batteries are good and powerful enough.
