1. Check the exterior of all ECG leads (three/five extension cords in contact with the human body should be connected to the corresponding three/five contact pins on the ECG plug. If the resistance is infinite, it means that the wire is open and the wire should be replaced). Method: Take out the wire and align the convex surface of the wire plug with the groove of the "ECG" jack on the front panel of the host.
2. This electrocardiogram cable can be interchanged with other machines to confirm whether the electrocardiogram cable is faulty, whether the cable is aging, or the pins are damaged.
3. If the ECG display waveform channel displays "No Signal Receiving", it means there is a problem with the communication between the ECG measurement module and the host. This prompt still exists after turning off and on, and you need to contact the supplier.
