1.6 Types of Leakage Current Measurement

Chapter 1

Overview

This is electric current that flows through an "

applied part

of malfunctioning medical equipment



human

body



F-type applied part

" path.

The measurement of this leakage current is required only for medical devices with an

F-type applied part

Instead of connecting damaged medical equipment to generate a

single-fault condition

, input a voltage

that is 110% of the rated voltage.

Patient leakage current measurement
(external voltage on a specific F-type applied part)
