Things You'll Need
Instructions
Choose a wall or other surface around your house or boat to mount the Schatz onto.
Gently hammer the hooks into the surface over the two middle loops of the barometer to mount.
Tap the metal frame of the barometer gently to get a reading; the barometer's pressure needle will move to the right if the weather is drying out, it will move to the left if it is either raining or about to rain and it will not move if the weather is holding steady.
Write down the reading you get on the barometer with the pencil and paper; for example, if the reading is "760 mm" and "Change," then write down "760 mm Change." Note the needle with no end is the one that reads the pressure, while the one with the curved end reads temperature.
Check the barometer periodically and write down the reading the pressure needle gives with pencil and paper. Compare the readings you've written down over time to track weather.
