Question
The purpose of the "set" hand on an aneroid barometer is to:Select the correct response:provide a correction for height above sea levelindicate any change in the reading of the barometerprovide a correction for temperature changesadjust the barometer
Solution
The purpose of the "set" hand on an aneroid barometer is to indicate any change in the reading of the barometer. This hand is manually adjusted to rest directly above the barometer's current pressure reading. Then, as the atmospheric pressure changes and the barometer's reading changes, the difference between the "set" hand and the current reading can be easily seen, showing how much the pressure has increased or decreased.
