5.
Plug the probe adapter into the meter’s connector marked ”EXTERNAL” (Refer to ILLUSTRATION 3–7).
6.
Set the meter’s ”FUNCTION” switch to EXTERNAL position.
7.
Add the saline probe and the imaging area of the probe into the saline bath.
8.
Have unit power ON for the first part; turn it OFF for the second half.
9.
Depress the ISO TEST rocker switch and record the highest current reading.
10. Follow the test conditions described in the following table (TABLE 3–6) for every transducer.

Meter Procedure
Follow these steps to test each transducer for leakage current.
1.
Turn the RTfino/RT3200 Advantege-II/RT-x200 unit OFF.
2.
Plug the unit into the test meter, and the meter into the tested AC wall outlet.
3.
Plug the external probe into the meter’s ”EXTERNAL” connector.
4.
Set the meter’s ”FUNCTION” switch to EXTERNAL position.
5.
Connect the probe for test with the connector of the console.
Note
Do not test all the probes on the same XDIF connector. Use all three slots eventually.
6.
Apply a liberal amount of gel to the transducer’s lens.
7.
Wrap the transducer in aluminum foil, making sure there is good contact with its acoustic aperture.
8.
Either suspend the transducer by its cable or place it on an insulated surface.
Note
Lift only one probe at a time from its resting hook.
9.
Have unit power ON for the first part; turn it OFF for the second half.
10. Hold the external probe against the aluminum foil on the transducer when the unit is ready to scan.
11. Depress the ISO TEST rocker switch and record the highest current reading.
12. Follow the test conditions described in the following table (TABLE 3–6) for every transducer.
13. Keep a record of the results with other hand copies of PM data.
