| Abstract: | The inner structure and operating principle of non-contact magneto potentiometer are described. The noncontact magneto potentiometer is one of the main parts of the electrocardiographic magnetic sensing position feedback recorder, which is important for the electrocardiograph to operate normally. If magneto potentiometer has any problem, it will result in some faults. Based on the analysis about the common faults, static method and dynamic method are provided. At last, some suggestions and reference are presented for detection and maintenance. |
