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 than 45°.
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 5°-10°,
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.
