Chapter 1 Overview
Patient auxiliary current is current that flows through an "applied part human body applied part" path.
Regardless of the medical equipment class, type of applied parts, and signal input/output selection, all
medical equipment with multiple applied parts must undergo this measurement.
Make both AC and DC measurements for this type of leakage current.
This is electric current that flows through an "applied part
 human body  ground" path.
Regardless of medical equipment class, type of applied parts and signal input/output section, all medical
equipment with patient connections must undergo this measurement.
Make both AC and DC measurements for this type of leakage current.
