**** Isolation between Mains and Applied Limits refers to the measurement of leakage current flow
which would flow from mains to patient if the patient were to come into contact with mains voltage.
The following tests are performed at the factory and should be performed at the customer site as well.
- Grounding Continuity
- Earth Leakage Current.
- Enclosure Leakage Current
- Patient Leakage Current
All measurements should be made with an electrical safety analyzer.
