Chapter 2: Commissioning Procedures 41
Carry out the procedure for either Speed calibration for conventional speed
transducer or the Speed calibration for smart transducer, as appropriate for your
vessel.
Speed calibration for conventional speed transducer
When calibrating a conventional Speed transducer, you can obtain correct values for
the calibration factor by one of two methods:
• If SOG information is available, you can use this as a reference, to enable you to
set the correct calibration factor.
• If SOG information is not available, you have to manually calculate and apply the
correct calibration factor.
Carry out the Starting speed calibration procedure (below) followed by either:
• the Set to SOG procedure (page 42), or
• the Manual speed calibration procedure (page 42)
as required.
Starting speed calibration
To calibrate the Speed transducer:
1. With the
Transducers Found
menu displayed
(see Preliminary procedure on page 38), use
the appropriate Instrument keypad to scroll to
the
Speed
option.
2. Press
OK
to select the
Speed
transducer setup
menu.
3. Scroll to the
Calibration
option.
4. Press
OK
to select the
Speed
Calibration
screen.
5. Press
PAGE UP
to highlight the calibration
speed field.
6. Scroll to select the lowest calibration speed.
7. Apply the appropriate calibration factor, using
one of the following:
• If SOG information is available, use the Set
to SOG procedure.
• If SOG information is not available, carry out
the Manual speed calibration procedure (on
page 42)
