Chapter 4: Calibration 33

Adjust to SOG

The Adjust to SOG screen is displayed only if SOG data is available
from SeaTalk. The current SOG is displayed in the bottom section of
the display (SG12.8 in the illustration), and the current speed registered
by the instrument, as large figures in the middle section of the display
(12.3 in the illustration).
It is recommended that, if you are running in slack tide conditions, you
press the reset key for 3 seconds, to accept the SOG as the current
speed.
If you do not wish to accept SOG as the current speed, press the trip
and reset keys together to select the Cal factor adjust display.

Cal factor adjust

The Cal factor adjust screen enables you to manually adjust the
calibration factor. It shows the current calibration factor in the bottom
section of the display (CF 1.00 in the illustration), and the current speed
as large figures (12.3 in the illustration).
Use the trip or reset key to adjust the calibration factor so that the
current speed is the speed through the water.
If SOG data is available from SeaTalk, you can turn to the Adjust to
SOG screen by pressing the trip and reset keys.
Note: If neither of the above methods gives satisfactory results, carry
out the Speed calibration procedure (part of Intermediate calibration).
