The ultrasound probes imaging area is immersed in the Saline solution along with a grounding probe from
the test meter to complete the current path.
This test is also known as Patient Leakage Current.
1.
Turn the Voluson E-Series system OFF.
2. Connect the Safety analyzer to an AC wall outlet.
3. Set the Safety analyzer's function switch to "Chassis" or "Enclosure Leakage".
4. Plug the Voluson E-Series system's power cord into the test meter.
5. Plug the Chassis Ground Probe (saline probe) into the test meter's “CHASSIS” connector.
6. Connect the ultrasound probe to be tested to the Voluson E-Series system.
7. Immerse the saline probe in the saline solution.
8. Immerse the Voluson E-Series probe´s face (imaging area of the probe) into the saline solution.
Caution
To avoid probe damage and possible electric shock, do not immerse probes into any liquid beyond the level
indicated shown below.
Do not touch the probe, conductive liquid or any part of the system under test while doing the test.
Caution: Equipment damage possibility!
Never switch the Polarity and the status of Neutral when the Voluson E-Series system is powered ON.
Power off the Voluson E-Series system, allow the stored energy to bleed down, and turn the circuit breaker
off BEFORE switching the "POLARITY" switch and/or the "NEUTRAL" switch on the leakage meter to avoid
possible power supply damage.
9. Test opening and closing the ground with the Voluson E-Series system on and off.
a.
Power ON the Voluson E-Series.
b. After the Voluson E-Series system has completed the boot process, select the probe to be tested
so it is the active probe.
c. Depress the "LIFT GROUND" rocker switch and record the highest current reading.
d. Follow the test conditions and test limits described in
*
Table 10-10 on page 10-11
, as applicable for every probe.
10. Record the highest current reading.
The test passes when all readings measure less than the stated limits.
