To measure the hourly rate of operation
1
Use the chronograph to measure
the time required to complete 1
job.
2
Locate the second marker on the
main dial that corresponds to the
measured seconds, and the
tachymeter scale it indicates gives
the average number of jobs
accomplished per hour.
Ex. 1
“180” (tachymeter scale figure) x
1 job = 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
“180” (tachymeter scale figure) x 15 jobs = 2700 jobs/hour
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
