Theory behind the Tachymaster,
using the example of the Tachymaster 50
At a stipulated average speed of 50 km/h,
the vehicle covers 13.888 m/sec. It therefore
needs 36 seconds to cover a distance of 500 m.
The Tachymaster 50 has been designed in
such a way that the measuring hand also
takes precisely 36 seconds to complete one
revolution.
The arrangement of the dial shows distances
rather than time segments. On all Tachymasters,
one revolution equates to 500 m, and the
reading is accurate to less than 2 m.
The total number of complete kilometres
which have already been covered is shown by
the small hand positioned below the 500 mark.
Special rally stages are therefore immediately
visible up to a distance of 30 km.
This description also applies to the
Tachymaster 30 and the Tachymaster 40.
(Average speed 8.333 m/sec. respectively
11.111 m/sec.; revolution 60 seconds
respectively 45 seconds)
