Stimulation Pulse Terminology

The term "pulse duration" or "pulse width" refers to the length of time from point A to point B. The "pulse amplitude" refers to the output
level reference from points C and D with the rated load. See Figure 1.

Accuracy of Controls

Stimulator values are determined by the operator based on the electrophysiological responses and the subjective reaction of the patient to the
stimulus, therefore an accuracy of ±30% pro vides acceptable levels for safe use of this equipment in the intended applications.
