Mindray M7T - Mains on Applied Part Leakage Test; Patient Auxiliary Current Measurement

D-4 Electrical Safety Inspection
 LIMITS
For BF applied parts,
 100µA in Normal Condition.
 500µA in Single Fault Condition.
D.8 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage,
through a limiting resistance, to selected applied part terminals. Current measurements
are then taken between the selected applied part and earth. Measurements are taken
with the test voltage (110% of mains) to applied parts in the normal and reverse polarity
conditions.
The following outlet conditions apply when performing the Mains on Applied Part test.
 Normal Polarity;
 Reversed Polarity.
 LIMITS
 For BF applied parts: 5000 µA.
D.9 Patient Auxiliary Current
Patient Auxiliary currents are measured between any selected Applied Part connector and
the remaining Applied Part connectors. All measurements may have a true RMS only
response.
The following outlet conditions apply when performing the Patient Auxiliary 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 BF applied parts,
 100µA in Normal Condition.
 500µA in Single Fault Condition.
Note: Make sure the safety analyzer is authorized comply with requirement of
IEC61010-1.
Follow the instructions of the analyzer manufacturer.
