Calibrating a digital compass is fairly simple process if you know how to force it into its calibration mode. You need an open space to begin the process. Determine whether your compass is a handheld compass or an automatic compass, then set your compass to calibration mode. In an open area, make two full circles within 20 seconds. Turn the calibration mode off. The entire process can take up to 10 minutes based on experience.Continue Reading
Press the button or buttons required to set your compass to calibration mode.
If you have a handheld compass, hold your compass in both hands with your arms stretched out in front of you. In a slow movement, move your body in a full circle two times in a row. The two full circles need to be made within a 20-second period to be read properly. If you have an automatic compass, set the compass in the final place. Go to an open field, and move your body in a full circle two times in a row. Repeat this process if needed.
Press the button or buttons to bring the compass out of calibration mode. The compass is now calibrated.
