2.10 Patient (sink) leakage current test (mains voltage on
the applied part)
This procedure only applies to Class I (grounded/earthed) equipment, and measures the
leakage current from a mains voltage source into the ECG/RESP connector or the SpO
2
connector.
The patient connector test body shorts all signals in the connector together. Refer to the
instructions contained with the safety analyzer to perform this test. Connect the ECG/RESP Test
Body to the green connector of the device under test.
Refer to the instructions contained with the safety analyzer to perform each test.
NOTE: The MD represents the network and voltage measuring instrument and its frequency
characteristics per IEC 60601-1.
NOTE: Per IEC 60601-1, the impedance to protect the circuitry and the person performing the
test, but low enough to accept currents higher than the allowable values of the LEAKAGE
CURRENT to be measured.
(1) 1. Configure leakage tester as follows:
• Polarity - NORMAL
• Neutral - OPEN
• GND (Earth) - CLOSED
WARNING Shock hazard. The following step causes high voltage at the test body. Do
not touch the test body.
(2) Power on device under test.
(3) Read and record leakage current indicated on the tester.
(4) Change leakage tester switches to:
• Polarity - NORMAL
• Neutral - OPEN
• GND (Earth) - CLOSED
(5) Read and record the current leakage indicated on the tester.
