What is altimeter for?

Question

i have a altimeter in my car (delica l300) and i notice that it is rising when i'm travelling. And what is the use of its controller in the lower side.

Answer 1

To measure height above sea level. The controller on the left side must be to calibrate it with a known altitude. Read the owners manual that came with the vehicle. Look in the index at the back of the manual under altimeter.

Answer 2

The altimeter is an instrument optional in off-road vehicles to aid in navigation. Some high-performance luxury cars which were never intended to leave paved roads, such as the Duesenberg in the 1930s, have also been equipped with an altimeter.

Mountaineers use wrist-mounted barometric altimeters when on high-altitude expeditions, as do skydivers
