6.2 Earth Leakage Current
This test is in compliance with IEC60601-1 earth leakage current. The applied voltage for
IEC60601-1 is 264 Volts AC (110% of the highest rated mains voltage) 50 to 60Hz.
1) Configure the electrical safety analyser as recommended by the analyser operating
instructions.
2) Connect the monitor’s AC plug to the electrical safety analyser as recommended by the
analyser operating instructions.
3) Perform test as recommended by analyser operating instructions.

Note : Earth leakage current is measured under various conditions of the AC mains and
protective earth conductor. For each condition, the measured leakage current must not
exceed that indicated in the table above.
Note
: NC-Normal Condition / SFC-Single Fault Condition / RM - Reverse Mains/Line Voltage /
OS- Open Supply.
Note : All measurements shall be made with the power switch in ‘ON’ position.
6.3 Patient Leakage Current
This test measures patient leakage in accordance with IEC60601-1, clause 19, for Class1,
Type CF equipment. Patient leakage current in this test is measured from any individual
patient connection to earth (power ground).
1) Configure the electrical safety analyser as recommended by the analyser operating
instructions.
2) Connect the monitor’s AC plug to the electrical safety analyser as recommended by the
analyser operating instructions.
3) Wrap NIBP cuff tightly around appropriate metal cylinder (for FM830Encore only).
4) Connect a test cable between the cylinder and an input connector on analyser.
5) Turn on FM8x0Encore.
6) Perform the patient leakage current test as recommended by the analyser operating
instructions.
7) Repeat the patient leakage current test for all patient connections, using the appropriate test
cables.
Note : Contractions transducer (TOCO/IUP) socket has no direct patient connections. The
patient leakage current can be measured by wrapping the transducer in aluminium foil
and then attaching the test cable to the foil.
