speed per hour.
2
Ex. 1Ex. 1
Second hand:
40 seconds
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles
and 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
Tachymeter scale: “90”
* Tachymeter scale can be used only when the time required is less than 60 seconds.

English
19
To measure the hourly rate of operation

the time required to complete 1
job.
1
Tachymeter scale indicated by
Second hand gives the average
number of jobs accomplished per

2
“180” (tachymeter scale figure) x 1 job
= 180 jobs/hour
Ex. 1Ex. 1
Ex. 2: If 15 jobs are completed in 20 seconds:
“180” (tachymeter scale figure) x 15 jobs = 2700 jobs/hour
