Kandungan Pengukuran:
1.1. Kekonduksian dan Keluk Susceptance:
Mengukur parameter kekonduksian dan kepekaan transduser dalam jalur frekuensi 40kHz–120kHz.
1.2. Menghantar Respons:
Mengukur tindak balas penghantaran transduser dalam jalur frekuensi 40kHz–120kHz.
1.3. Menerima Sensitiviti:
Mengukur tindak balas penghantaran transduser dalam jalur frekuensi 40kHz–120kHz.
1.4. Arah Menegak:
Mengukur kearah menegak transduser pada 80kHz.
1.5. Ujian Tekanan Hidrostatik:
Transduser harus menahan tekanan hidrostatik tidak kurang daripada 1 MPa.

Ujian Tekanan Hidrostatik:
Selepas menjalani ujian tekanan hidrostatik pada 1 MPa/1j, 0 MPa/0.25j, 1 MPa/1j, dan 0 MPa/0.25j, rintangan penebat antara elektrod positif dan negatif transduser adalah lebih daripada 100 MΩ.
