Compass Sensor Calibration
The compass should be calibrated before use OR when the battery is replaced.
In COMPASS mode, hold “COMPASS” button for 3 seconds to enter the compass sensor calibration mode,
press COMPASS button to start the calibration
Keep the unit in a level position or on top of a non-metallic table/desk, reference to the arrow showing in LCD,
rotate the compass clockwise for one full rotation slowly.
When finished, LCD will display “OK” if the calibration is successful or display “Fail” if it is failed as below.
(2) Set the Declination Angle
The angle between magnetic north and the true north direction is called magnetic declination. The earth’s
magnetic poles fluctuate over time, and it also varies from place to place. Finding the declination on the map or
website, then set the declination on this unit to offset the difference between magnetic north and true north.
Please note that if you fail to do this, the readings you get from the compass could be in error.
In COMPASS mode, hold “COMPASS” button for 3 seconds to enter the compass sensor calibration mode,
press
“MODE”
button to enter setting of declination angle. The angle would flash on the LCD. (for example, as
below, “ 0° ” will flash on the LCD)
Press “
▼
”or “
▲
”to change the angle value, range from -90°to 90°, and press “MODE” button to confirm and
exit the setting.
TEMPERATURE
When compass mode is off, the top 2 row LCD display will provide the reading of temperature with unit of °C
or °F, the range from -20°C to 60°C.
