Patient (Sink) Leakage Current Test (Mains Voltage On The Applied Part) - GE CARESCAPE Monitor B850 Technical Manual

Patient (sink) leakage current test (mains voltage on the applied
part)
5-14
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
SpO2 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.
**Per IEC 60601-1, the resistance to protect the circuitry and the person
performing the test. The resistance must be low enough to accept currents higher
than the allowable values of the leakage current to be measured.
1. Configure leakage tester as follows:
Polarity – NORMAL
Neutral – CLOSED
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.
