2.9 Patient (source) leakage current test
This procedure only applies to Class I (grounded/earthed) equipment, and measures the
leakage current from the ECG/RESP connector or the SPO2 connector of the device to ground.
NOTE: The MD represents the network and voltage measuring instrument and its frequency
characteristics per IEC 60601-1.
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.
(1) Connect the ECG/RESP Test Body to the green connector of the device under test.
(2) Configure leakage tester as follows:
•
Polarity - NORMAL
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(3) Power on Device under test.
(4) Read and record the current leakage indicated on the tester.
(5) Change leakage tester switches to:
•
Polarity - NORMAL
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(6) Read and record the current leakage indicated on the tester.
(7) Change leakage tester switches to:
•
Polarity - NORMAL
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(8) Read and record the current leakage indicated on the tester.
(9) Change leakage tester switches to:
•
Polarity - NORMAL
•
Neutral - OPEN
