Using the Stopwatch

Whenever you perform a lap/split time operation, the stopwatch stores a record of the lap/

Lap Times and Split Times

A lap time is the time that elapses during a specific portion of the race, such as a lap around a track, while a split time is the time that elapses from the beginning of a race up to a certain point.

split time. There is enough memory to hold up to 60 lap/split time records. For each measurement operation, the watch also creates and store a title screen (which also takes up one record in memory) that shows the distance and the date of the measurement. The watch calculates the distance covered using elapsed time, based on a fixed pace.

In the Timekeeping Mode, press the C button once to enter the Stopwatch Mode.

For the stopwatch to be able to perform distance calculations, you need to use the procedure under “Configuring Individual Preferences” to specify your stride length and other information.

Whenever you press the D button to reset the stopwatch to all zeros, the data from the last measurement operation is stored in memory.

Pressing the A button to restart the stopwatch without resetting it to all zeros resumes elapsed time measurement from where it was last stopped.

When you first start an elapsed time measurement, the lower part of the display shows hours, minutes, seconds, and 1/100 second, while the upper part shows minutes, seconds, and 1/100 seconds. When the time in the lower part of the display reaches 10 hours, it switches to hours, minutes, and seconds. The upper part of the display switches to hours, minutes, and seconds when its time reaches one hour.

The watch will exit the lap/split screen automatically after about eight seconds.

Memory

The watch’s memory can be divided into multiple measurement logs. Each log has its own title screen that shows the distance and date of the measurement, which takes up one memory record. The memory’s maximum capacity is 60 lap/split time records, plus at least one log title screen, for a total of 61 records.

When memory becomes full, the watch automatically deletes old data to make room for newly measured data.

Example 1: Memory usage when the current elapsed time measurement is the only one in memory

Log Title Screen + 60 lap/split records = 61 records

An elapsed time measurement is one that runs from when the stopwatch is started from all zeros, until it is again reset to all zeros.

Example 2: Memory usage when there are multiple elapsed time measurements in memory

Measurement 1: Log Title Screen + 30 lap/split records = 31 records

Measurement 2: Log Title Screen + 29 lap/split records = 30 records (31 + 30 = 61 total)

For information about recalling stopwatch records, see “Viewing Stopwatch Records”.

Data Save Timing

Whenever you press the D button to display a lap/split, the lap/split time and distance are stored in memory. Stopping the elapsed time operation and pressing the D button to reset the stopwatch to all zeros stores the final distance in memory.

Memory Full

Storing data when memory is full automatically deletes the oldest record currently in memory to make room for the new data.

Example 1: When the current log is the only one in memory

Recording a new lap/split record while memory is full causes the oldest lap/ split time currently in memory to be deleted to make room for the new one.

Example 2: When there are multiple records or logs in memory

All of the records of the oldest stopwatch log are cleared to make room for the new data.

To clear memory data manually, see “To clear measurement log data”.

Viewing Stopwatch Records

Enter the Recall Mode when you want to view stopwatch records.

In the Timekeeping Mode, press the C button twice to enter the Recall Mode.

Entering the Recall Mode displays a title screen showing the number of the newest measurement log.

To search for lap/split data

While the title screen of the measurement log you want is displayed, use the A and D buttons to scroll through the lap/split time records in the log.

Holding down either button scrolls the records at high speed.

The location (upper or lower part of the display) of the lap and split times is the same as what you selected in the Stopwatch Mode.
