摘要： Manufacturing of magnetometer units (20′) employs a test socket (41) having a substantially rigid body (43) with a cavity (42) therein holding an untested unit (20) in a predetermined position (48) proximate electrical connection (50) thereto, wherein one or more magnetic field sources (281, 332, 333, 334, 335, 336) fixed in the body (43) provide known magnetic fields at the position (48) so that the response of each unit (20) is measured and compared to stored expected values. Based thereon, each unit (20) can be calibrated or trimmed by feeding corrective electrical signals back to the unit (20) through the test socket (41) until the actual and expected responses match or the unit (200) is discarded as uncorrectable. In a preferred embodiment, the magnetic field sources (281, 332, 333, 334, 335, 336) are substantially orthogonal coil pairs (332, 333, 334) arranged so that their centerlines (332-1, 333-1, 334-1) coincide at a common point (46) within the predetermined position (48). Because the test-socket (41) is especially rugged and compact, other functions (e.g., accelerometers) included in the unit (20) can also be easily tested and trimmed.
摘要翻译：磁力计单元（20'）的制造采用具有基本刚性体（43）的测试插座（41），其中空腔（42）将未测试单元（20）保持在接近电连接（50）的预定位置（48）其中固定在主体（43）中的一个或多个磁场源（281,332,333,334,335,336）在位置（48）处提供已知的磁场，使得每个单元（20）的响应是测量并与存储的预期值进行比较。基于此，可以通过将校正电信号通过测试插座（41）馈送到单元（20），直到实际和期望的响应匹配或单元（200）被丢弃为不可校正来校准或修整每个单元（20）。在优选实施例中，磁场源（281,332,333,334,335,336）是基本上正交的线圈对（332,333,334），其布置成使得它们的中心线（332-1,333-1,334,334） 1）在预定位置（48）内的公共点（46）处重合。由于测试插座（41）特别坚固和紧凑，所以包括在单元（20）中的其他功能（例如，加速度计）也可以容易地进行测试和修整。

摘要： Manufacturing of magnetometer units employs a test socket having a substantially rigid body with a cavity therein holding an untested unit in a predetermined position proximate electrical connection thereto, wherein one or more magnetic field sources fixed in the body provide known magnetic fields at the position so that the response of each unit is measured and compared to stored expected values. Based thereon, each unit can be calibrated or trimmed by feeding corrective electrical signals back to the unit through the test socket until the actual and expected responses match or the unit is discarded as uncorrectable. In a preferred embodiment, the magnetic field sources are substantially orthogonal coil pairs arranged so that their centerlines coincide at a common point within the predetermined position. Because the test-socket is especially rugged and compact, other functions (e.g., accelerometers) included in the unit can also be easily tested and trimmed.
