5.1.2.2 Patient Leakage Current Test
This test performs a leakage current test under single fault conditions (S.F.C.) depending
on domestic power outlet with 115 or 230 V AC as source into the floating inputs.
In all cases, the leakage current is measured from input jack of unit under test to ground.
Connect the unit under test to your Safety Tester.
- Referring to the electrical diagram, measurements have to be done under the following
conditions:
* Polarity switch NORM and RVS
* GND switch GND closed
* S1 closed
Test has failed if the measured values are greater than 50 µA
