waters2695进样时发现仪器报警，出现solv delivery motor lost sync ，以后看到有人说重启就行，我重启了好多次，结果仪器自检都不通过，显示plunger homing fault(0)和general solv delivery fault，怎么办呀？什么原因，修的话很贵吗？可以自己修吗？请各位大侠指教，感激不尽！！！！！！[img=,690,920]https://ng1.17img.cn/bbsfiles/images/2018/06/201806172235594599_3602_3055719_3.png[/img][img=,690,920]https://ng1.17img.cn/bbsfiles/images/2018/06/201806172236007727_5065_3055719_3.png[/img][img=,690,920]https://ng1.17img.cn/bbsfiles/images/2018/06/201806172236019419_4502_3055719_3.png[/img]
