CSIP Level 1 Performance Tests: Test and Inspection Matrices
Activate the transducer. Is the transducer
recognized by the system (its ID label
appears on the screen) and does it image?
NOTE: Turn the gain up to ensure that the
transducer will image. Dip the transducer
tip in water and verify that there is an image
throughout the sector.
If all answers were “yes,” the
transducer passes.
Important Condition:
Perform the Sbf test if a
transthoracic “BF” transducer passes
all of the above tests, yet has minor
physical damage which normally does
not result in transducer replacement,
but does warrant verifying electrical
integrity. Ti will still be Pass (from a
physical perspective). Passing or failure
of the electrical integrity test is
indicated in the Sbf test results.
Ti:P
or
Ti:F
(“sn” is the last 5 digits of
the serial number of the
transducer that failed, and
P = Pass and F=Fail)
Sbf:
Safety—
Transthoracic
Transducer
(BF Type)
Only perform this test if, during the Ti or
Tn test, minor damage to a transthoracic
“BF” transducer indicates the need to verify
electrical integrity.
Measure the leakage current of the
transducer using test setup described in
“Electrical Safety Tests” on page 143.
(x) Leakage current, source (single fault)
(y) Leakage current, sink (mains voltage
applied)
(x)< 500 μA (UL/IEC/CSA)
(y)< 250 μA (UL/IEC/CSA)
If transducer is within above
limits, the transducer passes,
and you record test data.
Sbf(sn):P/x/y
or
Sbf(sn):F/x/y
(x and y = uA
measured, sn = last 5
digits of serial number,
P = Pass and F = Fail)
