T1 Service Manual 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.
