Mindray VS-900 - Earth Leakage Test; Patient Leakage Current

E-3
E.5 Earth Leakage Test
Run an Earth Leakage test on the device being tested before performing any other
leakage tests.
The following outlet conditions apply when performing the Earth Leakage test:
 normal polarity (Normal Condition),
 reverse polarity (Normal Condition),
 normal polarity with open neutral (Single Fault Condition),
 reverse polarity with open neutral (Single Fault Condition)
LIMITS
For UL60601-1,
 300 A in Normal Condition
 1000 A in Single Fault Condition
For IEC60601-1,
 500 A in Normal Condition
 1000 A in Single Fault Condition
E.6 Patient Leakage Current
Patient leakage currents are measured between a selected applied part and mains earth.
All measurements have a true RMS only
The following outlet conditions apply when performing the Patient Leakage Current test.
 normal polarity (Normal Condition);
 reverse polarity (Normal Condition),
 normal polarity with open neutral (Single Fault Condition);
 reverse polarity with open neutral (Single Fault Condition).
 normal polarity with open earth (Single Fault Condition);
 reverse polarity with open earth (Single Fault Condition).
LIMITS
For CF applied parts
 10A in Normal Condition
 50A in Single Fault Condition
