Hello, I have purchased a BMP388 from you the other day and have just received it today. I am now testing it and have come across a big problem. Using a simple test script - making sure the sea level pressure is accurate etc. I get an altitude reading of 200m, which is a lot considering the highest point in my county (Norfolk) is 103m and my altitude is about 16m (I think). Could I have received a dodgy sensor or could there be another problem?
