Patient (Source) Leakage Current Test - GE Dash 3000 Service Manual

Patient (source) leakage current test

8-12
Functional and electrical safety checks: Electrical safety tests
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 – CLOSED

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
