Figure 50: Gain adjustment
• 1x Gain (± 4 mV): 1x Gain should be selected when the signal amplitude is large
enough to cause clipping when the 2x gain is selected.
• 2x Gain (± 2 mV): 2x Gain should be selected when the signal amplitude is small
enough to allow use of a more sensitive setting without causing
clipping of the captured signal. The 2x gain selection amplies
the signal twice as much as the 1x gain selection.
To program the manually selected sense conguration:
1. Select the Program button to save the sense vector and gain settings.
2. The Acquire Reference S-ECG process is automatically enabled during the Manual
Setup Process. Select the Continue button to acquire a reference S-ECG. A
conrmation screen will appear when the captured reference S-ECG is acquired
(Figure 51).
3. Select the Continue button.
