Arahan horizontal
Uji tekanan hidrostatik
Setelah hidrofon diuji tekanan hidrostatis 2Mpa/1 jam, 0Mpa/0,25 jam, 2Mpa/1 jam, dan 0Mpa/0,25 jam, hidrofon tidak mengalami kerusakan atau kelainan di bagian luar, dan resistansi isolasi antara elektroda positif dan negatif hidrofon lebih besar dari 200 megohm, dan resistansi isolasi antara elektroda positif dan negatif serta pelindung lebih besar dari 200 megaohm.
