故障现象：红细胞计数部分报警，仪器提示堵孔（Clog），T1=6．00S，T2＝0．00S，所有红细胞、血小板的计数值均为空白，仪器无法使用。分析与检修：引起红细胞计数，堵孔报警（Clg，T1＝6．005，T2＝0．005）的原因主要来自以下三个方面：（1）真空泵压力小，引起T1延长。（2
Symptoms: The red blood cell count alarmed, and the instrument prompts a clog, T1=6.00S, T2=0.00S. All red blood cells and platelet counts are blank and the instrument cannot be used. Analysis and maintenance: Cause red blood cell count, blocking hole alarm (Clg, T1 = 6.005, T2 = 0.005) The main reasons come from the following three aspects: (1) vacuum pump pressure is small, causing T1 extension.
