Raymarine ST60 Tridata - Manual (Page 45)

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).

Tridata instrument being calibrated, on and off.
Leaving User calibration
