8.2.5 Patient Leakage Current Test
This test performs a leakage current test under single fault conditions (S.F.C.) dependent of
domestic power outlet with 115 or 230 V AC as source into the floating inputs.
In any case, the leakage current is measured from Input Jack, of unit under test, to ground.
For testing the ECG input, a patient cable, with all leads connected together, is used.
Connect the unit under test to your Safety Tester.
