ECG Signal
WARNING
Operation of your system with ECG signals below 0.25 mV may cause inaccurate
results.
The amplitude of the electrocardiogram (ECG) signal is critical for reliable frame
triggering. Frame triggering should be used only when a clean, noise-free ECG
waveform is observed on the ECG display. The ECG signal should be at least
0.25 mV to ensure reliable triggering when the system is used in the presence
of the electromagnetic phenomena described in this section and elsewhere in
your system user information.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD), commonly referred to as a static shock, is a
naturally occurring phenomenon that results in the flow of an electrical charge
from a higher charged object or person to a lower charged object or person.
ESD is most prevalent during conditions of low humidity, which can be caused
by heating or air-conditioning. During low humidity conditions, electrical charges
naturally build up on individuals and objects and can create static discharges.
The following cautions can help to reduce ESD effect:
