SPEED AND LOG CALIBRATION
Before Network QUAD 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 QUAD unit,
two manual adjustments and one automatic:
MANUAL CALIBRATION
1. CAL The displayed boat speed value is corrected
manually to read a known measured speed.
2. LOG The units calibration figure (Hz/Knot) is
CAL 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 QUAD unit.
