摘　　要：研制了地磁台磁变仪标定器。该标定器采用集成电路,使标定过程完全呈线性变化,标定程序简单易操作,从而极大地提高了标定电流的稳定性及整个标定质量。We have manufactured the calibrator for the variometer used at the geomagnetic station. The integrate circuit in adopted in the calibrator, which makes the calibration process present a linear variation. The calibration procedure is easily operated and so the stability of calibrating current and the whole quality are highly improved.
