一、实验前的检查1.接通电源观察自检程序:正常情况下,仪器立即出现负压泵起动声。当内部负压达到一定要求,泵自动停止,前面极依次出现六项自检指标。10秒后指示灯为绿色。如有异常,将指出故障。2.检查各功能键是否正常:拨动 RBC/WBC 转换键,RBC、WBC 指示灯应变化;拨动Wash Supply 键,液体应流人仪器中,并有电磁阀开动声;拨动 auto/clear 键 HGB 窗口出现零。清除时,按动计数键,10秒后显示窗应有数
First, the test before the test 1. Turn on the power observation self-test program: under normal circumstances, the instrument immediately start negative pressure pump sound. When the internal negative pressure reaches certain requirements, the pump will stop automatically. There are six self-check indicators in front of the pump. After 10 seconds the light is green. If abnormal, will indicate the fault. 2. Check each function key is normal: Turn RBC / WBC switch key, RBC, WBC indicator should be changed; Toggle Wash Supply key, the liquid should flow into the instrument, and solenoid valve start sound; Turn auto / clear The key HGB window appears zero. Clear, press the count button, 10 seconds after the display should be a few
