TACHYMETER*
The Tachymeter is the device which measures the speed of an automobile. Knowing is
how many seconds the car covers a distance of 1km, the meter can measure the
approximate average speed per hour during a journey (up to the maxinum measurable
range of tachymeter is 60 seconds).
If the chronograph is started at the same time as measurement, and stopped after 1km,
the average speed per hour can be determined according to the position of the second
hand. If the car covers the distance of 1km in 45 seconds, the average hourly speed
during the journey will be about 80 km.
