ES601Plus OPERATING MANUAL
When testing patient leakage, ES601Plus can be configured to record the following AC and DC values for
each group of parts defined in the test setup:
Normal Polarity Normal Condition
Single-Fault Condition, Line 2 Open
Single-Fault Condition, Earth Open
SFC, Mains on Applied Part(s)
(1)
(NP:NC)
(NP:SF L2O)
(NP:SF EO)
(NP:SF MAP)
Reverse Polarity Normal Condition
Single-Fault Condition, Line 2 Open
Single-Fault Condition, Earth Open
SFC, Mains on Applied Part(s)
(1)
(RP:NC)
(RP:SF L2O)
(RP:SF EO)
(RP:SF MAP)
(1) Type BF or CF applied parts only; not tested for Type B
Under the IEC60601 standard, patient connections within "Type CF" groups are tested individually in turn.
In this case, for each normal (NC) and single-fault (SF) condition ES601Plus will record the number of the
patient connection that produces the highest leakage.
In addition to NC and SF conditions listed above, IEC60601 and AAMI-ES1 standards require
supplementary test conditions (STC). ES601Plus allows the user to optionally enable or disable the STC in
the leakage setup, according to the characteristics of the DUT. Optional STC include:
• performing tests with the DUT power switch in the "ON" position and also in the "OFF" position
(ON/OFF test conditions);
• applying mains supply voltage to isolated signal inputs/outputs on the DUT, or connecting such
1
isolated signals to protective earth (MIO/IOE test conditions), and;
• connecting floating (ungrounded) metal parts on the DUT to protective earth (ME test condition).
During the test, ES601Plus measures patient leakage for each NC or single-fault SF condition in
combination with all STC enabled by the user. For each NC or SF condition, ES601Plus records the
maximum leakage observed and the STC that produced the maximum leakage.
Patient leakage tests can be performed manually, but may be complex and time consuming to set up,
particularly if there are a large number of applied parts or supplementary test conditions to specify. To save
you time, ES601Plus allows you to program and save such setups as automated test sequences, which are
further described in Section 2.1.12.
An example of an isolated signal input/output would be a transformer-coupled data connection, for example,
1
an Ethernet communications port on the DUT.
