SPEED AND LOG CALIBRATION

Before Network SPEED is used for navigation the boat speed

and log have to be calibrated to ensure accuracy for your

installation and the boats hull characteristics.

Three methods are available with the Network SPEED unit,

two manual adjustments and one automatic:

MANUAL CALIBRATION

1 SPEED The displayed boat speed value is

corrected manually to read a known

measured speed.

2 LOG CAL The units calibration figure (Hz/Knot) is

manually adjusted to correct log and

speed inaccuracy.

AUTOMATIC CALIBRATION

3 AUTO CAL The unit automatically calibrates and

corrects the boat speed and log.

Use the one of the methods overleaf to calibrate your

instrument. It is recommended that AUTO CAL is used as

this method will ensure the most accurate calibration of your

Network SPEED unit.
