Instructions | JA-600G six channel ECG is such a kind of electrocardiograph,which samples 12 leads ECG signals simultaneously and prints out the ECG waveforms with thermal printing system. Its functions are as follows:recording and displaying ECG waveforms in auto/manual mode;auto-measuring and auto-diagnosing the ECG wave parameters;prompting the state of lead off and paper lack;switching the interface lauguages (Chinese/English);managing the case database. |
