熙寧六年六月，提舉司天監陳繹言：「渾儀尺度與《法要》不合，二極、赤道四分不均，規、環左右距度不對，遊儀重澀難運，黃道映蔽橫簫，遊規璺裂，黃道不合天體，天樞內極星不見。 In the sixth month of the sixth year of Xining, Chen Yi, supervisor of the Directorate of Astronomy, reported: "The armillary sphere's measurements do not agree with the Essentials of Methods. The two poles and the equator's four quarters are uneven, the distance graduations on the rings do not match left and right, the sighting arm is too heavy to turn smoothly, the ecliptic band is blocked by the crossbeam, the touring sight-ring is cracked, the ecliptic fails to align with the heavens, and the pole star within the celestial pivot cannot be seen.
