3. SPLIT/LAP TIME MEASUREMENT
“Split time” refers to an elapsed time required to
cover a distance from the start to a given point.
“Lap time” refer s to an elapsed ti me required to
cover a given section of the whole distance.

Split time
• Up to 300 lap/split time data of one measurement can be stored in memory and recalled on display.
• With each press of “C,” the stored data is recalled. The data can be recalled successively one after another by keeping “C” pressed.
• The stored data can be recalled even during measurement (while the stopwatch is measuring).
• Memory recall sequence
When the stopwatch is stopped, with each press of “C,” the stored data will be recalled from the first (oldest) to the last (newest) data.
When the stopwatch is measuring, with each press of “C,” the stored data will be recalled from the last (newest) to the first (oldest).
MEMORY RECALL FUNCTION------- SINGLE MEMORY MODE
*The data can be recalled successively by keeping “C” pressed.
*To stop the recall of the data when the stopwatch is stopped, press “A”, “B” or “D.”
To stop the recall of the data when the stopwatch is reset, press “A” or “D.”
With each press of “C,” the data is recalled chronologically (starting from the first/oldest data).
Ex.: When the stopwatch is reset to “00” after the measurement

MEMORY RECALL WHEN THE STOPWATCH IS STOPPED OR RESET
RECALL mark appears while the stored data is being recalled on display.
The mark shows the memory recall sequence (descending/ascending).

measurement will be automatically
deleted.
MEMORY RECALL FUNCTION------- BLOCK MEMORY MODE
The Cal. 141 features a dual memory mode:
Single memory mode..... The single memory mode is the default-set mode. The lap/split time data of one measurement from start to stop can be stored.
When the stopwatch is reset, and a new measurement is commenced, the lap/split time data of the previous measurement will
be automatically deleted.
Block memory mode ......The block memory mode is an advanced mode designed for professional level use. A sequence of measurement data obtained
from start to stop (or reset) is recorded as a “block.” Up to 100 blocks of data can be stored in memory without deleting the
previous data.

<How to change the memory mode>

1. While in the TIME/CALENDAR display, press “B” 8 times until “BLOCK” appears on the display, above which either “ON” or “OFF” is flashing.
2. Press “A” for 1.5 seconds until the memory mode changes with a long beep.
Benefits of block memory mode
Easy data management ............The block number as well as starting time and date of measurement are automatically recorded and stored.
Handy data storage................ Creation of a new block of data will not erase the previous data in memory. While in the single memory mode,
a new measurement will delete the latest measurement data.

mark appears at the bottom right on the display regardless
of the display mode.
