Measurement direction and installation requirements The azimuth measurement of a 3D electronic compass is based on the principle of geomagnetic induction, and its installation environment must meet strict magnetic interference control requirements. To ensure measurement accuracy, the following installation specifications should be followed: 1. Magnetic Environment Requirements: The installation location should be far away from ferromagnetic materials (such as iron products, permanent magnets, etc.) and electromagnetic equipment (such as motors, transformers, etc.); the minimum distance from potential...

Calibration prerequisites: 1) The compass accuracy does not meet the requirements; 2) If there is a fixed magnetic field interference in the compass installation environment (e.g., installed on ferrous materials), the interference source and the compass must be rotated synchronously for calibration, and their relative positions must be kept fixed during use; otherwise, recalibration is required. If the size or distance of the interference source is not fixed (e.g., a variable iron component), calibration is not possible; a safe installation distance of at least 30cm should be maintained. 1) Place...
