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. 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.
