Operation Guide 3731

The stopwatch measures elapsed time in units of 1/100 second up to 59 minutes, 59.99 seconds (60 minutes). When the maximum limit is
reached, the elapsed time automatically returns to zero and timing continues from there. Performing a lap/split operation automatically
stores lap/split times in memory (up to 50 records). A simple operation lets you recall lap/split time records when you need them.
How Hands Operate in the
Stopwatch Mode
In the Stopwatch Mode, elapsed time is indicated both by the
digital display and by the hands of the watch. Resetting the
stopwatch to zero causes the hands to return to the 12 o’clock
position.
• In the Stopwatch Mode, the second hand indicates elapsed
seconds, while the battery level indicator dial indicates elapsed
minutes.
• When you start an elapsed time operation in the Stopwatch Mode
and when you exit or enter the Stopwatch Mode while an elapsed
time operation is in progress, the stopwatch 1/20-second hand
rotates for one minute. After that it stops at the 12 o’clock position.
Stopping the elapsed time operation causes the hand to move to
the current 1/20-second position.

To perform stopwatch operations
Start Lap/Split Time Recording Stop
Press the button. Press the button.Press the A button.
• This starts the elapsed time operation.
• Starting a new elapsed time operation
from zero deletes all lap and split time
data currently in lap/split time memory.
• This freezes the current time on the
digital display for five seconds, and
stores it in lap/split time memory.
Elapsed time measurement continues
internally at this time.
• Though the digital time freezes, the
stopwatch hands continue to move.
• This stops the elapsed time operation.
• Pressing the A button while timing is
stopped resets the stopwatch.
Resetting the stopwatch stores the final
elapsed time that is on the display to
lap/split time memory.

split time operation when there are already 50 records in memory
automatically deletes the oldest record to make room for the new
times.
