4.5.7
Tactical use of [MEM]
Function [MEM] is used to discover the smallest of wind shifts
during upwind or downwind sailing, but it is your tactical decision
wheter to tac or to stay on course. The Compass Data instrument
will automatically keep track on wheter you are using the starboard
or port MEM if the course difference between each trim is more
then 45º. There is also a new function called [KTR] (Knock TimeR),
giving you the time spent i seconds when sailing below a preset
”knock Angle”. Both [MEM] and [KTR] will help you to get a very
good ”picture” over actual windshifts, both in size and time.
How does it work ?
On the optimum compass heading, press the trim or
SET
button to
store your present course in the memory called MEM. Your actual
course is then constantly compared with MEM and displayed as a
lift or as a header. Each time you press trim or
KEY
, a new
reference course is set.
How to use the MEM function:
When you are sailing at a good speed and with the sail trimmed,
press trim or
SET.
The Compass Data will then store the present
course in memory MEM as a reference. If you then have a lifter,
press TRIM again, but if you have a header more then 5º-10º,
tack.
After you tack, re-trim the sails and get a good boat speed before
you press trim or
SET
again. Now you have set a new reference in
the memory. Whenever you get a lifter, press TRIM, but when you
get a header,
tack.
Your previous trim reference will automatically
be displayed and used.
Now, add the KTR timer
The timer must first be activated. This is done by setting the CAL
value C-17 to the maximum angle where you consider your boat to
be pushed off course, i.e. where you normally would tac when
getting a header. See more under [KTR] setup.
4.5.8
Battery voltage [BAT]
The text [BAT] will display battery voltage. The voltage is measured
inside the instrument and will not compensate for any voltage drop
caused by installation.
4.5.9
Boat speed [BSP], option
The text [BSP] will display boat speed (water speed). The text
[BSP] will toggle with selected unit, i.e. (KTS), (KMH) or (MPH).
As an option, you may add or remove displaying boat speed
[BSP], trip log [TRP] and water temperature [TMP]. See
calibration.
