Rally ADD function (partial times)
This function starts like the SIMPLE function.
Used for measuring successive events, but not the intervals between
them. Each result is automatically added to the preceding one.
To time the various stages of a car rally, for example:
At the start of the fi rst stage, press push-piece A to start the
chronograph.
After the fi rst time measurement (STOP), provided that push-piece
B (RESET) has not been pressed, you can RESTART (push-piece
A) to add a new time to the previously measured time.
After STOP has been pressed, the 60-SECOND, SPLIT-SECONDS and
30-MINUTE counter hands will stop running. The 1/10th of a SECOND
counter hand displays the value in tenths of a second as it runs.
After STOP (push-piece A) has been pressed, engage a RESET
(push-piece B) to fi nish timing, and return the chronograph to
watch mode.
At the end of the fi nal stage the chronograph will show the total time
of the rally, in other words, the accumulated time for all the stages..
Repeat this procedure for each stage of the rally.
Press push-piece B to reset.
