Setting up the EMG system

All EMG systems are different but some settings will be good starting places.

Stimulus Repetition Rate:
Artefact Rejection
Most EMG systems have a method to disable or enable different levels of Artefact rejection.
methods will vary with manufacturer and model.
Depending on the particular set-up used, the DS7A can often produce large amplitude stimulus artefacts.
These can produce a "reject" of the recorded sweep.
If this is the case the Artefact Rejection should either be turned-off (disabled) or set to ignore the large
transients (stimulus artefacts) in the first part of the sweep.
