摘要:A cardiac defibrillator is a medical electrical device used to defibrillate the heart of patients. In JJF1149-2014, defibrillator analyzers are used to measure the output energy of cardiac defibrillators, whose energy accuracy is an important parameter. This manuscript describes establishment of calibration equipment for defibrillator analyzer, including voltage divider module, sampling module and data processing module. Measurement uncertainty is evaluated for measurement results at last.
