心电图机的抖动故障是指在输入端短路时，热笔描记出不规则波形的现象，如果波形的电乎超过了心电图机的噪声要求，即称为抖动，它与干扰的主要区别在于干扰是指在有心电信号输入时产生的波形失真。抖动是维修中经常遇到的故障之一，下面列出造成抖动故障的主要原因及相应的处
The electrocardiograph’s dithering fault refers to the phenomenon that the thermograph traces an irregular waveform when the input terminal is short-circuited. If the waveform’s power exceeds the noise requirement of the electrocardiograph, it is called jitter. The main difference between it and the interference is that the interference is Refers to waveform distortion that occurs when an ECG signal is input. Jitter is one of the common faults encountered during maintenance. The following are the main causes of the jitter faults and their corresponding locations.
