仪器型号 multimode IIIa

目前激光强度始终只有1左右，反光镜用乙醇擦过，针也换新的，但仍然上不去。想问一下，是哪里出问题了？

有工程师说只有用contact 模式的针才有可能达到4-5，用tapping的针最大就到2，是这样吗？

SUM的高低和探针的背面有没有镀层有关。MultiMode一般用的tapping mode的探针是没有镀层的RTESP探针，一般SUM在1.5-2.5V左右，contact探针一般是背面镀金的，一般能达到4-7V左右。其他可能造成激光强度低的因素有：1. 探针没有装好，2. Head后面的反射镜的角度不对，3. 光检测器位置太偏。请确认装针的位置正确，在CCD下看到激光确实打在了悬臂前段的位置，调节Head后的反射镜使SUM变大，然后调节光检测器使SUM最大。如有问题，请直接拨打400-890-5666.
