1830 Compass: Failure - A compass failure has occurred
This error occurs when the compass (within the scanner) detects a strong magnetic field. In this condition, the compass direction may not be accurate during scanning.
Check for large motors, magnets, smart phones, AC adapters, computers, or other electromagnetic devices within the scanning environment or in close proximity to the scanner. If possible, remove or reposition the offending device or reposition the scanner to a more suitable location.
Compass Sensor - General information
The accuracy of compass measurements can be affected by magnetic or other environmental interference. An indicator of the strength of environmental interference and thus of the current compass measurement accuracy is the displayed Horizontal field strength of the magnetic field. The typical strength of the earth's magnetic field depends on geographical position and varies from 0.3 to 0.6 gauss (G). The displayed horizontal field strength is lower than the absolute field strength because of the inclination of the field. For example, the typical horizontal field strength for Europe is about 0.2 gauss.
If the measured field strength differs significantly from the expected field strength, there might be a strong artificial magnetic field near the scanner that probably affecting the measurement. For the most reliable orientation data and scan registration, avoid positioning the scanner near strong magnetic fields. If the measured horizontal field still significantly differs, you can switch the use of the compass data to OFF.
