Measuring Elapsed Time; Measuring A Split Time - Casio 3522 Operation Manual

Lunitidal Interval
●
Theoretically, it is said that high tide (peak
tide) occurs when the moon reaches the
meridian (Figure 1), and low tide (ebb tide)
occurs about six hours later. However, in the
real world, the effects of seawater viscosity,
friction, and sea floor topography delay the
high tide to some point after the meridian
(Figure 2). This time differential is the "lunitidal
tide interval".
The lunitidal interval differs from one region
(port) to another, even within the same country
or geographic area.
Figure 1
Tidal force is at its peak when the Moon is at
the meridian.

The stopwatch measures elapsed time in units
of 1/100 second up to 23 hours, 59 minutes,
59.99 seconds (24 hours).
When this maximum limit is exceeded,
elapsed time measurement returns to 0 and
timing continues from there.
