As shown above, when 5 LEADS is selected, five labels are located above the ECG

waveforms:

ECG lead of channel 1 (Primary lead)

You can select the lead of channel 1 from the label options.

•

When you use a 3-lead set, the monitor gives three lead options: I, II and III;

•

When you use a 5-lead set, the monitor gives seven lead options: II, III, aVR, aVL,

aVF, V and I.

Gain of the channel-1 waveform

You may use this label to adjust the amplitude of the channel-1 ECG waveform. The

gain options include ×0.125, ×0.25, ×0.5, ×1, ×2 and AUTO. When AUTO is selected,

the monitor adjusts the gain automatically. Besides, a 1mV scale is displayed at the right

side of each ECG waveform. The height of the 1mV bar is directly proportional to the

ECG waveform amplitude.
