Leakage Current Test Setup - Welch Allyn VDX-300 Operating Manual

Welch Allyn VDX-300 Illumination and Imaging System
Leakage Current Test Setup
When the VDX-300 camera system is used in conjunction with other video accessories
(such as printers and VCRs), it may be necessary to measure the leakage current of the
entire setup. A typical setup is shown in Figure 6 below. Using a standard leakage
tester, this setup will allow the overall system leakage current to be measured. An
isolation transformer must be used if the leakage current exceeds 100 microamperes, in
order to conform with EN60601-1 standards. The maximum allowable leakage current
of the patient applied part (Type F endoscope) is 100 microamperes.
