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.
s
“180” (tachymeter scale gure) x
1 job =
180 jobs/hour
CHRONOGRAPH
second hand:
20 seconds
Tachymeter
scale : 180”
Ex. 2: If 15 jobs are completed in 20 seconds:
“180” (tachymeter scale gure) x 15 jobs = 2700 jobs/hour
tachymeter scale:
“90” (tachymeter scale gure) x 2 (km or mile) = 180 km/h or mph
“90” (tachymeter scale gure) x 0.5 (km or mile) = 45 km/h or mph
NOTES ON OPERATING THE WATCH
ADJUSTING CHRONOGRAPH HAND POSITION
l
Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, the date may not
change properly.
l
When setting the hour hand, be sure to check that AM/PM is correctly set. The watch
is so designed that the date changes once in 24 hours.
* Turn the hands past the 12 o’clock marker to determine whether the watch is set
for the A.M. or P.M. period. If the date changes, the time is set for the A.M. period.
If not, the time is set for the P.M. period.
l
When setting the minute hand, first advance it 4 to 5 minute ahead of the desired time
and then turn it back to the exact minute.
TIME/CALENDAR SETTING
l
The "0" position of the CHRONOGRAPH 1/10-second hand differs depending on the
models.
* Some models have the “0” position of the CHRONOGRAPH 1/10-second hand at
3 and 9 o’clock sides of the small dial. In that case, check if the hand is level with its
both ends pointing to those “0” positions.
l
The CHRONOGRAPH minute hand moves correspondingly with the CHRONOGRAPH
second hand.
l
The hands move quickly if the respective buttons are kept pressed.
