10-20 Section 10-6 - Electrical Safety Tests
• Check probe current leakage, as shown below:
NOTE: Because the Vivid q N scanner is operated from low voltage DC (considered extremely safe
extra low voltage) and because the transformer is enclosed in plastic parts only (and therefore
does not have any accessible metal parts),
when the scanner is not mounted on the
SafeLock Cart , it is not necessary to perform the following safety tests (i.e., they apply only to
the SafeLock Cart itself):
• Chassis Current Leakage Test
• Grounding Continuity Test
Probe Frequency for Checking
Surface
Once per year
(or in accordance with QA program)
Endocavitary
Twice per year
(or in accordance with QA program)
Any probe
Whenever damage is suspected
