JJG543-96 the EEG machine "metrological verification regulations, ECG machine the main test items have: appearance and its normal work inspection, voltage measurement, sensitivity, time interval, go paper speed, hysteresis, the default standard voltage, time scale, impulse, time constant, amplitude frequency characteristic, filter, high polarization voltage, common mode rejection ratio, the width of the baseline, baseline drift, noise, inter electrode resistance measurement and input impedance of 19. One of the failed, the electrocardiogram machine that was sentenced to failure. Although there is a good quality of domestic ECG machine, but still has a large gap with foreign brands.
