4.4 Barometer Calibration

Your barometer will operate from -100 to 3,000 feet with reliable accuracy. Aneroid barometers have a

small screw on the back for sea-level calibration. With a flat blade screwdriver, turn this screw in

either direction slightly while looking at the indicator needle. It should move in one direction or the

other. Tap the barometer to see where the needle settles. Continue this procedure until the proper

pressure reading is obtained. Do not turn the screw counter-clockwise (to the left) too far, since the

screw can fall out. After the initial calibration, no further adjustment will be required unless the

barometer is moved to a new geographic location.

5. Dial Thermometer

The dial thermometer uses a bimetallic strip wrapped into a coil. One end of the coil is fixed to the

housing of the device and the other drives an indicating needle. The principle behind a bimetallic strip

thermometer relies on the fact that different metals expand at different rates as they warm up. By

bonding two different metals together, the coil bends, causing the needle to move. Bimetallic

thermometers are not as accurate as bulb (mercury or red spirit) thermometers. The dial thermometer

should require no calibration.

6. Installation

To install the traditional weather station, hang the plaque on a wall with the hole built into the plaque.
