Rev. 5
Isolated Probe (Sink) Leakage-Isolation Test
Measurements should be recorded for probes and transducers
under each set of test conditions specified in:
• Table 4-8 on page 4-21
Record all data and keep the record of the results with other
hard copies of maintenance data.
1. Connect the Safety analyzer to an AC wall outlet.
2. Plug the equipment under test into the receptacle on the
panel of the Electrical Safety Analyzer.
3. Connect the Ultrasound probe to be tested to the Ultrasound
system.
4. Immerse the saline probe in the saline solution.
5. Immerse the Ultrasound probe’s face (imaging area of the
probe) into the saline solution.
6. Select the “Patient Lead Leakage” function on the Electrical
Safety Analyzer.
7. Test with closed ground with the Ultrasound system on and
off.
NOTE: For more information, refer to the safety analyzer's user manual.
WARNING
Do not use the probe if the insulating material has been
punctured or otherwise compromised. Integrity of the insulation
material and patient safety can be verified by safety testing
according to IEC60601-1.
CAUTION
Line voltage is applied to the ultrasound probe during this test.
To avoid possible electric shock hazard, the system being
tested must not be touched by patients, users or anyone while
the ISO TEST switch is depressed.
