I have a PTB110 barometer connected to a CR1000 data logger. It operated without any issues for more than two years before it started reporting incorrect values. After some time, the readings became accurate again. I replaced the barometer with another identical unit. Before installation, I tested the new barometer under laboratory conditions and confirmed that it was working properly. The new barometer initially provided correct measurements, but after two weeks it also began reporting incorrect values. Could you please advise what might be causing this issue?
