1 Name of the First ECG Lead:
ECG using 5-lead, the selectable leads include I, II, III, aVR, aVL, aVF and V;
ECG using 3-lead, the selectable leads include I, II and III. (For neonate)
The leads on the ECG waveform should not have the same name, otherwise the
system will automatically change the similar name into another.

2 The 1st-ECG Waveform Gain: used to adjust the amplitude of ECG waveform.
The gain of each calculation channel can be selected, which has such columns as
×0.25, ×0.5, ×1 and ×2 as well as auto mode. Auto mode means that the monitor can
automatically adjust the gain. On the right side of each ECG waveform there is a 1-mv rod
of which height and amplitude are proportional.
Caution
The input signal being too strong, the wave crest may be truncated. At this time users
can manually change the gain column of ECG waveform by reference to the actual
waveform for fear of incompleteness of waveform.
