Barometer Problem

Hi Everyone
Does anyone know what causes barometer to become erratic like this one. Computer running WD 24/7, this happens about everyday. The low pressures do not showup on the weather station. Everthing else is working great.

Thanks Joe

it looks like i am not handling the barometer reading from the good ol heatkit

(i.e i will need to get some raw data from you,etc)
