About Stopwatch Memory
Whenever you perform a stopwatch operation, measured times are automatically stored into memory along with the lap number. You can store up to 30 lap/split times in memory. If you perform more than 30 lap/split time operations, the memory will contain the times for the last 29 laps/splits (as lap/split numbers 1 through 29), and the final lap and split time (as lap/split 30). � Both lap time and split time data is stored in memory, regardless of whether you performed a lap time or split time measurement. � Data in lap/split memory is cleared whenever you start a new stopwatch operation. � The final elapsed time or final lap/split time is stored in memory when you press A to stop the stopwatch.
