1. Connect the simulator to the unit and select the calibrated ECG reference wave-
form EN 60601-2-51 > CAL 20160.
2. Press the Auto Start key to make an auto mode recording printout.
3. Check measurement table (given on the printout) against the following table.
4. Check the waveform and polarity against the reference waveform given on the
