常规
通常每次开机后进入治疗前都必须进行自检。
所有关系到安全的功能都将被测试，确保治疗安全进行。
治疗开始前不可跳过自检。
仅在自检程序完全通过后开始治疗程序才是安全可靠的。

SAD 测试
监测板测试步骤 30000 - 30009 水平测试
SAD 测试分为两个步骤
1. SAD 水平测试
测量测试水平与定标水平进行比较。
重启动机器或重新定标SAD。
如果已经放入血路管，不会影响该测试。
2. 计数测试
检查测试脉冲的长短。
Code LLC - 3002x - 3099x
测试脉冲是由控制板发出的测试信号，监测板同时监测接收计数。
计数失败则说明LLC, LLS 或 SAD硬件故障
