The most common use of a tachymeter is for
measuring the approximate speed of a vehicle
over a known distance.
(E.g.) Based on how many seconds it takes a
vehicle to travel 1 km or 1 mile (the available
measuring range is up to 60 seconds), the
average speed within the distance can be
calculated.
1. Start the chronograph when the vehicles
commence travel.
2. After the vehicle has travelled 1 km/1 mile,
stop the chronograph.
The approximate average speed within the
distance can be determined by observing the
present position of the stopwatch second hand
and reading the outer bezel.
