Stopwatch

1/100 secondHours

Minutes Seconds

The stopwatch lets you measure elapsed time, lap times, split times, and two finishes. Lap times and split times can be stored in memory.

• The display range of the stopwatch is 99 hours, 59 minutes, 59 seconds.

• All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.

Note

• “Lap time” is the time spent to cover a specific segment of a race, such as one lap around a track. “Split time” is the time spent from the beginning of a race up to a certain point.

Operation Guide 4380 4396 5048

• The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.

• The stopwatch measurement operation continues even if you exit the Stopwatch Mode.

• For information about how stopwatch times are stored in memory, see “Memory Management”.

Viewing the Stopwatch Digital Displays

The information that appears in the watch’s upper and lower digital displays depends on whether you are measuring lap times or split times.

Lap Time Measurement

Upper Display: Lap time Lower Display: Elapsed time

Split Time Measurement

Upper Display: Lap time Lower Display: Elapsed time (Split time appears here for eight seconds as it is stored

• See “To measure elapsed time with lap times” and “To measure elapsed time with split times” for more information about each type of measurement.

• You can perform elapsed time measurement starting from either the lap time screen or the split time screen. Whenever you enter the Stopwatch Mode, the screen (lap time or split time) that was displayed when you last exited the mode will appear first.

• During a stopwatch elapsed time operation, the upper display initially shows minutes, seconds, and a 1/100-second value. This changes to hours, minutes, and seconds when the time in the upper display exceeds 60 minutes.

• The lower display initially shows hours, minutes, seconds, and a 1/100-second value. This changes to hours, minutes, and seconds when the time in the lower display exceeds 10 hours.

To measure elapsed time

Note

• You can perform the following steps starting from either the lap time screen or the split time screen.

1. Press D to start the stopwatch.

2. Press D again to stop the stopwatch.

• You can resume the measurement operation by pressing D.

3. Press A to clear the stopwatch to all zeros.

1. When the stopwatch display shows all zeros, press

A to display the lap time screen (indicated by LAP).

2. Press D to start an elapsed time measurement.

• At the time, both the upper and lower displays will show identical times.

3. Press A to record the time of the first lap.

• This freezes the current lap time in the upper part of the digital display for about eight seconds, while measurement of total elapsed time and the next lap time continue internally. The lap number of the displayed time appears in the lower digital display.

• After eight seconds, the ongoing elapsed time measurement re-appears in the lower digital display.

4. Repeat step 3 to record more lap times.

5. Press D to stop the stopwatch.

6. Press A to clear the stopwatch to all zeros.

• Lap numbers are incremented automatically starting

from 1 whenever you press A in step 3 of the above procedure. The maximum lap number is 99. Recording a lap after that causes the lap number count to restart from 00.

1. When the stopwatch display shows all zeros, press A

2. Press D to start an elapsed time measurement.

• At the time, both the upper and lower displays will show identical times.

3. Press A to record the time of the first split.

• The current split time appears in the lower display for about eight seconds, as the total elapsed time, next lap time, and next split time continue to be timed internally by the watch. The split number of the displayed time appears in the upper display.

• After eight seconds, the ongoing lap time measurement appears in the upper display and the ongoing elapsed time measurement appears in the lower display.

4. Repeat step 3 to record more split times.

5. Press D to stop the stopwatch.

6. Press A to clear the stopwatch to all zeros.

• Split numbers are incremented automatically starting

from 1 whenever you press A in step 3 of the above procedure. The maximum split number is 99. Recording a split time after that causes the split number count to restart from 00.

2. Press D to start a time measurement.

3. Press A when the first finisher crosses the finish line.

• This freezes the time of the first finisher in the lower part of the digital display for about eight seconds. After that, the display returns to elapsed time measurement.

4. Press D when the second finisher crosses the finish line.

• The second finisher’s time will appear in the lower display.

• The difference between the first finisher’s and the second finisher’s time will

appear in the upper display.

5. Press A to clear the stopwatch to all zeros.

Memory Management

A new log is created each time you press D in the Stopwatch Mode to start a new elapsed time measurement operation. A log contains a log title screen, and records of all the lap or split times you record during the current elapsed time measurement operation.

• The capacity of the watch’s memory is 60 records.

• If you are adding records to the only log in memory and watch memory becomes

full, adding another record causes the oldest record in the log to be deleted automatically to make room for the new record.

• If you are adding records to a log when there are multiple logs in memory and watch memory becomes full, adding another record causes the oldest log in memory and all of its records to be deleted automatically to make room for new records.

How stopwatch data is stored

The following table shows how stopwatch data is stored when you perform stopwatch button operations.

To recall stopwatch time records

1. In the Stopwatch Mode, check to make sure that the displays reset to all zeros.

• If all zeros are not displayed, reset the stopwatch.

2. Use the A button to select either the lap time screen (to view lap time records) or

the split time screen (to view split time records).

• To convert a lap time saved in the Stopwatch Mode to a split time, select the split time screen.

3. Press the C button to enter the Recall Mode.

4. Use the A button to scroll through the log title screens from the newest to the

oldest until the title screen of the log whose records you want to view is displayed.

5. Press D to scroll through the records contained in the log you selected in step 4,

from the oldest to the newest.

• Whether you will be able to view lap time records or split time records will depend on the screen you selected in step 2, above.

To delete a log

1. In the Recall Mode, display the title screen of the log you want to delete.

2. Hold down B and D until CLR stops flashing on the display.

• This deletes the log and all the records inside it.

• Deleting a single log slides all newer logs (ones with higher log numbers) upwards to

fill the empty space. This cause the log numbers of all the newer logs to be reduced by 1. If there are six logs currently in memory (numbered 01 through 06) and you delete log 03, the numbers of logs that previously were numbered 04, 05, and 06 will change to 03, 04, and 05.

Use the Recall Mode to recall and delete logs and records you stored in the Stopwatch Mode. You can use the Recall Mode to view both lap and split time records.

• When you enter the Recall Mode, the newest log recorded in the Stopwatch Mode will appear first. If there are no logs in memory,

• You can use the Recall Mode to check memory data even while a stopwatch elapsed time measurement operation is in progress. However, the time data that is currently being measured will not appear in the Recall Mode.

• You can convert a lap time saved in the Stopwatch Mode to a split time.
