How do you tell if a barometer is working?
Hold the instrument at the 45-degree angle and check the the level of the mercury in the glass tube with a long “stick” barometer. If the barometer is working correctly, the mercury inside will rise quickly to fill the very tip of the tube, leaving no air bubble.
Should you tap a barometer?
It is highly advisable to lightly tap the glass near the center brass knob with your fingers before taking a barometer reading. The light tap will overcome any friction that may affect accurate hand readings, especially during periods of slow atmospheric changes.
