B&G Network Quad - Manual (Page 11)

METHOD 1. - MANUAL CALIBRATION - CAL
This procedure requires a reference boat speed with which to
compare the Network QUAD 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 depend
ent upon the
accuracy of the reference boat speed.
The example below shows a displayed boat speed of 5.2
knots, the boat speed is known to be 6.0 knots. The
displayed value is adjusted to read 6.0 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 units memory. If
the speed and log are not functioning correctly then enter a
calibration value of 5.3 to 6.2 and then re-enter the correct
calibration value as described below.
