一．功能介绍在多年维修医疗仪器中，感到维修手段落后、费时费力还难以很好地完成维修任务，因此本人设计了一台多功能检测仪，用它可测量一路信号的幅度和周期、仪器设备上作为自检作用，更可通过与正常时比较（正常时所测或同型号另一台好机器所测存贮起来）查找故障作为检 one. Function description In the maintenance of medical instruments for many years, I feel that maintenance methods are backward, time-consuming and laborious, and it is difficult to complete the maintenance tasks well. Therefore, I designed a multi-functional detector that can measure the amplitude and period of one signal and equipment. As a self-test function, it can be checked by comparing the fault with the normal one (normally measured or stored by another good machine of the same model).
