8-12 Dash 3000/4000/5000 2000966-542D
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 – 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
