A: For ourbarometer, it seems this question is confused by some users. The atmosphericpressure changes very little if the weather does not change too much per day.It changes big and obviously only when the weather changes too much, such asthe typhoon, rain etc. To verify the meter works fine or not,simple way is to put the meter into one full air plastic bag then seals it, thenpress the bag (please see the video).
