A-1 
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.
