10.6.9.3 Isolated Probe (Sink) Leakage-Isolation Test
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.
Measurements should be recorded for full lead combination under each set of test conditions specified in:
•
Table 10-11 on page 10-11
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 meter.
3. Connect the ultrasound probe to be tested to the Voluson E-Series system.
4. Immerse the saline probe in the saline solution.
5. Immerse the Voluson E-Series probe´s face (imaging area of the probe) into the saline solution.
6. Select the "Patient Lead Leakage" function on the meter.
7. Test with closed ground with the Voluson E-Series system on and off.
Note
For more information, refer to the safety analyzer's user manual that will be used to perform the test.
Record all data and keep the record of the results with other hard copies of maintenance data.
