摘　　要：本文介绍了G858磁力仪的测量原理以及对仪器性能指标进行测试的情况,计算并分析了观测结果。数据处理结果表明,该仪器的噪声水平优于0.3nT,但观测误差与厂家标称精度相差较大;仪器之间一致性较好,互差小于1nT,无明显系统误差。This paper introduces the measurement principle of G-858 magnetometer and situation of performance test, calculates and analyzes the observation results. The processed data shows that this instrument noise level is better than 0. 3nT, but the difference between observation error and factory nominal accuracy is large. This instrument have a good consistency, less than lnT difference and no obvious system error.
