ES601Plus OPERATING MANUAL
Type BF refers to "Body-Floating" or "Isolated" protection class. That is, the applied parts are
electrically isolated from protective earth but are not intended for direct contact with cardiac tissue.
ES601Plus will measure patient leakage current while all the applied parts in the Type BF applied
part Group are shorted to ground, or alternatively to the isolated mains (AC supply).
Type CF refers to "Cardiac-Floating" protection class. The applied parts are electrically isolated
from protective earth and have been designed for direct contact with cardiac tissue. Type C parts
have the most stringent safety requirements. ES601Plus measures patient leakage current while each
applied part in the Type CF applied part Group is shorted to ground, or alternatively to the isolated
mains (AC supply).
Each applied part can be assigned a name. Applied part names can be input via the textboxes
provided in the Applied Part Name and Status panel.
8.5.19 Auxiliary (Interlead) Leakages
(IEC60601, AAMI-ES1, IEC60601-Battery and AAMI-Battery)
In this test, ES601Plus measures the current that flows out of one applied part, through the human
body load, and into all the other applied parts shorted together. The test will be repeated for each
applied part. This test is pertinent to IEC60601 and AAMI standards only.
8.5.20 Isolated Signals Inputs/Outputs
(IEC60601, AAMI-ES1, IEC60601-Battery and AAMI-Battery)
If Isolated Signals Inputs/Outputs is enabled, the effect on patient leakage by connecting isolated
input/output signals of the DUT to ground or to mains will be observed. An example of an isolated
input/output would be an ethernet connection or similar transformer-isolated data interface on a
medical device. This test is pertinent to IEC60601 and AAMI standards only.
When enabling tests of Isolated Signal Inputs/Outputs, the signals must be
isolated from protective earth, otherwise damage to equipment under test
may result. Check equipment manufacturer's specifications.
8.5.21 Exposed Ungrounded Metal Parts (IEC60601)
If Exposed Ungrounded Metal Parts is enabled, the effect on patient leakage by connecting exposed
ungrounded metal parts of the DUT to protective earth will be observed. An example of such a part
may be an electrically floating conductive faceplate, a fastener in a plastic enclosure, bracket, or
similar feature on the enclosure of the DUT. This test is pertinent to the IEC60601 standard only.
