B&G Network Speed - Manual (Page 11)

1 - MANUAL CALIBRATION - SPD CAL
This procedure requires a reference boat speed with which to
compare the Network SPEED units displayed boat speed. For
example, another boat with an accurate calibrated log, or if
the top speed of the boat is known this value can be entered
during a sea trial to correct the displayed value.
NOTE: The accuracy of this method is dependant upon the
accuracy of the reference boat speed.
The example below shows a displayed boat speed of 7.25
knots, the boat speed is known to be 10.0 knots. The
displayed value is adjusted to read 10.0 knots.
IMPORTANT NOTE: This method of calibration must not be
carried out at boat speeds of LESS THAN 3 KNOTS as
inaccurate values can be entered into the unit's memory. If
the speed/log are not functioning correctly enter a calibration
value of 5.3 to 6.2 and then repeat the procedure.
