Compass Calibration

and Environmental Interference

• It is important to know all digital compasses

wor1ls with Earth's magnetic field and is very

sensitive to different environments where

the earth magnetic

fields is distorted. such

as interference by closing to heavy meta

l,

home appliance, computer and high power

cable

...

etc.

•

To

keep a hiSh accurate heading information,

you must calibrate the compass

(1) when

the magnetic distort message "Err" is

continuously displayed (2) the numeric

heading information

w

~h

a error more than

10

degree (3) when the unit is used for the

first time in a vehicle so as to separate the

earth's field from the interference.
