TACHYMETER

(for models with tachymeter scale on the dial)
TO MEASURE THE HOURLY AVERAGE SPEED OF A VEHICLE
Use the stopwatch to determine
1
how many seconds it takes to
go 1 km or 1 mile.
2
Tachymeter scale indicated by
the STOPWATCH 1/5-second
hand gives the average speed
per hour.
l Tachymeter scale can be used only when the time required is less than 60 seconds.
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or
miles and the STOPWATCH 1/5-second hand indicates "90" on tachymeter scale:
"90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
"90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph
Ex. 1
