28 ST60+ Speed Instrument Owner’s Handbook
Adjust cal factor
The adjust cal factor screen enables you to manually adjust the calibration factor.
It shows the current calibration factor in the top right of the display, and the
current speed as large figures (12.4 in the illustration).
Use the
timer or reset button to adjust the calibration factor so that the current
speed equals the speed through the water.
If SOG data is available from SeaTalk, you can turn to the Adjust to SOG screen by
pressing the
timer and reset buttons.
Note:
If neither of the above methods gives satisfactory results, carry out the Speed cali-
bration procedure (part of Intermediate calibration).
Set temperature units
Select either °C or °F , as required.
Temperature calibration

Timer buzzer

Leaving User calibration
Hold down the speed and trip buttons for 2 seconds to save your settings, exit
User calibration and resume normal operation.
4.3 Intermediate calibration
Intermediate calibration enables you to:
• Check the instrument software version.
• Check the instrument status - either MASTER (transducer connected) or
REPEATER (no transducer).
• Carry out a calibration run over a measured distance to ensure accurate speed
readings.
To start Intermediate calibration, hold down the
speed and trip buttons for
approximately 4 seconds (see
Intermediate calibration
flow chart).
