    • Embodiments of systems for calibrating transducer-including devices include a board support structure, one or more motors, a motor control module, and a calibration control module. The board support structure holds a calibration board in a fixed position with respect to the board support structure. The motor(s) rotate the board support structure around one or more axes of a fixed coordinate system. The motor control module sends motor control signals to the motor(s) to cause the motor(s) to move the board support structure through a series of orientations with respect to the fixed coordinate system. The calibration control module sends, through a communication structure, signals to the transducer-including devices, which are loaded into a plurality of sockets of the calibration board. The signals cause the transducer-including devices to generate transducer data while the board support structure is in or moving toward each orientation of the series of orientations.

    • 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.
    • 磁力计单元的制造采用具有基本上刚性体的测试插座,其中具有空腔,其中将未测试单元保持在与其连接的电气连接的预定位置,其中固定在主体中的一个或多个磁场源在该位置提供已知磁场,使得 测量每个单元的响应并将其与存储的预期值进行比较。 基于此,每个单元可以通过将校正电信号通过测试插座送回单元进行校准或修整,直到实际和预期响应匹配或单元被丢弃为不可校正。 在优选实施例中,磁场源是基本上正交的线圈对,其布置成使得它们的中心线在预定位置内的公共点处重合。 由于测试插座特别坚固耐用,所以包含在本机中的其他功能(如加速度计)也可以轻松测试和修整。
