Operator's Manual DS7A - Constant Current Stimulator

Setting up the EMG system

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

Amplifier sensitivity: ~50

V / division

No. of Sweeps: 1

Artefact rejection: OFF

Stimulus Repetition Rate: 0.5 Hz (every 2 sec.) or EXTERNAL

Artefact Rejection

Most EMG systems have a method to disable or enable different levels of Artefact rejection. Precise

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.
