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.
