Lap Time

 

 

 

A lap time reading shows the time elapsed since the last

 

 

 

lap time reading was taken.

 

 

 

• If you want the watch to calculate the speed of each lap

 

 

 

(when all of the laps are the same distance), specify the

 

 

 

lap distance for the distance setting (page E-15).

 

 

 

• If you want the watch to calculate the speed of the entire

 

 

 

race, specify the race distance for the distance setting

 

 

 

(page E-15). A speed will be indicated each time you

 

 

 

take a lap reading, but these lap speeds will not indicate

Lap time

actual speed of the entire race.

To set up the stopwatch to take lap time readings

1.In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.

• If you need to reset the stopwatch to all zeros, press A.

2.Make sure that (lap times) is shown in the lower display.

•If (split times) is displayed, press Ato toggle it to.

To perform a lap time measurement

Select lap time () measurement and then perform the following button operations.

DStart ➝ ALap* ➝ ALap* ➝ DStop ➝ A Reset

* The lap time is released automatically in about 12 seconds.

• You can press Ato take lap readings as many times as you like.

• A lap number (#01 through #99) alternates with the lap hour value in the upper display while a lap time reading is displayed. If you take more than 99 lap readings, the lap number will restart from #00 following lap #99.

• Pressing D to stop elapsed time measurement displays the time (and speed if a distance is specified) of the final lap.

Split Time

A split time reading shows the time elapsed since the

beginning of the current time measurement.

• If you want the watch to calculate the speed of the race,

specify the race distance for the distance setting (page

• For split time readings, you can specify the total race

 

 

 

distance only. Though the watch will indicate a speed

 

 

 

each time you take a split reading, they will be based on

 

 

 

the total race distance, and so they will not indicate

Split time

actual intermediate split speeds.

To set up the stopwatch to take split time readings

1.In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.

• If you need to reset the stopwatch to all zeros, press A.

*The split time is released automatically if you do not press Awithin about 12 seconds.

•You can press Ato take split readings as many times as you like.

•The stopwatch continues elapsed time measurement internally while a split time reading is displayed. Pressing A to release the split will switch the lower display to the elapsed time measurement, or you also could press D to stop elapsed time measurement instead.

•Pressing D to stop elapsed time measurement displays the time (and speed if a distance is specified) of the final split (which is the overall elapsed time).

World Time

World Time digitally displays the current time in one of 48 cities (29 time zones) around the world. A simple operation swaps your Home City with the currently selected World Time City.

•The times kept in the World Time Mode are synchronized with the time being kept in the Timekeeping Mode. If you feel that there is an error in any World Time Mode time, check to make sure you have the correct city selected as your Home City. Also check to make sure that the current time as shown in the Timekeeping Mode is correct.

•Times in the World Time Mode are based on UTC offsets. See the “City Code Table” at the back of this manual for information about the UTC offsets that are supported.

•All of the operations in this section are performed in the World Time Mode, which you enter by pressing C (page E-7).
