padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障维修：如下<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />1.检查气泵和各管路发现均无漏气现象。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />2.检测血压泵发现血压泵一切正常。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />3.按打气键隐约感觉到有漏气，因为气阀和管路均无漏气所以检查放气阀，发现放气阀漏气。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />4.换上两个同型号的放气阀，发现故障解除。</p><p style="">故障现象：按打气键泵不启动。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障判断：按键问题或者血压板问题<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障维修：如下<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />1.检测按键发现按键没有问题。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />2.按打气键测量泵的电压发现没有电压。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />3.用万用表检测血压板发现一个稳压块只有输入电压没有输出电压。因此判断这出现问题。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />4.换上一个同型号的发现故障消失。</p><p style="">故障现象：开机后提示电池电量低需要充电<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障判断：电池坏损或者主板故障<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障维修：如下<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />1.进行替换法换一块电池后发现故障依旧。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />2.因为电池的充电电路在主板上，因此检测主板上的充电电路，发现电压比较器旁边的一个电阻烧坏，担心比较器也已经老化所以更换同一型号的电阻和电压比较器，故障消失。</p><p style="">故障现象：开机后显示屏显示两行参数<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障分析：因为各项参数正常所以排除主板故障。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障判断：排线故障或是显示屏故障<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障维修：如下<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />1.用万用表检测显示器和主板的连接线，检测结果均正常。因此排线故障排除。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />2.接一外接显示器发现显示参数一切正常说明是显示器问题。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />3.维修显示器驱动程序一切恢复正常。</p><p style="">故障现象：血压不能检测<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障判断：可能是血压板故障<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />故障维修：如下<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />1.开机后进行设备自检能够通过说明主板没有问题。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />2.检测血压泵，气阀，传感器均正常。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />3.进入血压校准菜单，按start键气泵工作压力稳定在240.按stop键电磁阀工作。说明都没问题，那么故障应该出现在DAS板。<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"  />4.检测DAS板发现压力传感器损坏，换上新的压力传感器一切恢复正常。</p><hr style="white-space: normal;"  /><p style="white-space: normal;
