A 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 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 consistent use of a safety analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step if an approved agency status is to be maintained. 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.
