4. Calibration
In calibration mode, there is a list of nine calibration values and set up modes.
The list starts at C10 and stops at C18. Calibration related to the speed
transducer has the text ST after calibration number and the depth
transducer has the text DT.
To move to the desired calibration group press UP and DOWN as required.
4.1. Enter and exit calibration
To enter the calibration mode press KEY until the text C10 RET ap-
pears.RET stands for return.
To exit calibration press KEY in C10 RET (return).
4.2. Calibration groups
4.2.1. C10 Return (RET)
To exit calibration press KEY in this when the text RET is displayed.
4.2.2. C11 Damping (SEA MID)
Damping is used to get the most stable reading for the situation. De-
pending on the weight of the boat and the sea conditions, you may
want to change the dampening of the reading. If SEA MAX is used, an
average of the speed over a longer period will be displayed. This func-
tion will not effect the update rate of the
display.
4.2.3. C12 Instrument type (Type LOG)
The Star SEA Data instrument can either be operating as a log
instrument (LOG), a depth instrument (DPT) or as a combined
log/depth instrument (ALL). There is also a demonstration mode built
into the instrument (DEM). If LOG is selected, only log functions will be
displayed. If DPT is selected only depth functions will be displayed.In
demonstration mode (DEM) all values are simulated without any trans-
ducers connected. Note! Trip and total distance will not be stored in the
permanent memory after power off in demonstration mode.
4.2.4. C13 Unit for speed (Unit KTS)
The unit for speed is selectable between knots (KTS),
kilometres/hour (K/h) or Miles /hour (M/h). To change unit press
KEY and select unit with UP or DOWN and confirm with KEY.
4.2.5. C14 Speed calibration (1.20 CAL)
Because of different shapes of the hull, the instrument has to be
calibrated. This calibration will effect speed, trip and total distance.
The range for the calibration is 1.00-1.99 where The calibration value
will be multiplied with the speed. To calibrate your log, run the boat at
normal speed a measured distance.
Compare the distance with the trip distance.
Calculate the calibration value with the following formula:
