实时测量人体表面心脏电位的模拟单通道、多通道心电图机的计量检定须按照JJG543-2008《心电图机》检定规程进行。而具有非线性系统及信号处理和用于特殊用途的心电图机(如数字心电图机、向量心电图机等)应根据各自具体情况进行检定。一、心电图机检定中应注意的问题由于心电图机的灵敏度较高,因此检定前一定要做好准备工作,检定过程中要规范操作,避免由于检定工作的错误影响对检定结果的判断。1.做好常规检查。其生产厂名、型号、出厂日期、编
Real-time measurement of the human body’s surface cardiac potential simulation Single-channel, multi-channel ECG measurement in accordance with the JJG543-2008 “ECG” test procedures. And with nonlinear systems and signal processing and for special purposes such as electrocardiogram machine (such as digital electrocardiograph, vector electrocardiogram machine, etc.) should be based on their specific circumstances. First, the electrocardiogram test problems should be noted Because of the high sensitivity of the electrocardiograph, the test must be prepared before the test, the calibration process to regulate the operation, to avoid the wrong test results of the determination of the test results. 1. Do a good job of routine inspection. The name of the manufacturer, model, date of manufacture,
