To measure the hourly rate of operation:
1 Use the stopwatch to measure the time re-
quired to complete 1 job.
2 Locate the second marker on the main dial
which corresponds to the number of seconds
measured. The number on the tachymeter
scale indicates the average number of jobs
accomplished in one hour.
* For the models with the tachymeter scale around the
small dial at the 6 o’clock position, read the tachymeter
scale which the STOPWATCH second hand points to.
●
Ex. : “180” (tachymeter scale figure)
x 1 job = 180 jobs/hour
STOPWATCH second hand:
20 seconds
Tachymeter scale: 180
● If 15 jobs are completed in 20 seconds:
“180” (tachymeter scale figure) x 15 jobs
= 2700 jobs/hour
