郎溪县数字心电图机检定数据

数据依据 JJF 1151 - 2006《数字心电图机校准规范》，对数字心电图机开展计量性能检测。将心电图机设定为正常工作模式，采用标准信号源输出模拟心电信号，输入至数字心电图机，待设备稳定显示后，读取并记录输出的波形、幅值、频率等参数，对比标准信号参数与设备显示参数，计算相关误差。各项误差在对应准确度等级允许范围内，判断其计量性能合格，以此评估数字心电图机计量性能。This dataset is developed based on JJF 1151-2006 *Calibration Specification for Digital Electrocardiographs*. Metrological performance tests are conducted on digital electrocardiographs as follows: First, set the electrocardiograph to normal working mode. A standard signal generator is used to output simulated electrocardiographic signals, which are input into the digital electrocardiograph. After the device's display stabilizes, parameters such as the output waveform, amplitude, and frequency are read and recorded. The standard signal parameters are compared with those displayed by the device, and the relevant errors are calculated. If all errors fall within the allowable range of their corresponding accuracy grades, the metrological performance is determined to be qualified, thus completing the evaluation of the digital electrocardiograph's metrological performance.
