This section explains how to measure lap times while watching a race, and check the difference between a lap time and target time. It also shows how you can view lap times with CASIO WATCHES after the race is over.

Before a race

At this time, you should specify the target time type. If you specify TARGET as the target value type, you should also specify the TARGET time.

You can use the CASIO WATCHES phone app to specify a measurement interval distance. Doing so will cause the mode hand to indicate the average time of the lap being timed.

During a race

Measure lap times.

1. Hold down (D) for at least two seconds.

This will cause the watch to enter the Timekeeping Mode.

2. Press (D) once.

This will cause the watch to enter the Stopwatch Mode.

3. Use the operations below to measure lap times.

Pressing (E) at the end of each lap will record each lap time in watch memory.

• Lap times are recorded in 1/1000-second units during the first hour of an elapsed time measurement session. After one hour, times are recorded in 1/10-second units.

• The difference between a lap time and a target time specified by you is indicated by the second hand.

Interpreting the Difference with the Target Time

4. Press (A) to reset the stopwatch time to all zeros.

5. Hold down (D) for at least two seconds to return to the Timekeeping Mode.

After a race

After the race is finished, you can view the measured lap times with CASIO WATCHES.
