Electrical Safety Inspection
The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program.
They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or
the operator. Additional tests may be required according to local regulations.
All tests can be performed by using commercially available safety analyzer test equipment. These procedures assume
the use of a 601PROXL International Safety Analyzer or equivalent safety analyzer. Other popular testers complying with
IEC 60601-1 used in Europe, such as Fluke, Metron or Gerb, may require modifications to the procedure. Please follow the
instructions of the analyzer manufacturer.
The electrical safety inspection should be periodically performed per years .The safety analyzer also proves to be an
excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads.
