Meting inhoud
1. Werkende frekwensieband
Die werkfrekwensieband van die omskakelaar is.
2. Stuur reaksie
Meet die transmissiereaksie binne die werkfrekwensieband van die omskakelaar, waarvan die waarde by 24kHz nie minder as 165dB moet wees nie.
3. Ontvangs van sensitiwiteit
Meet die ontvangsensitiwiteit binne die werkfrekwensieband van die omskakelaar, waarvan die waarde by 24kHz nie minder as -178dB moet wees nie.
4. Rigting openingshoek
@24kHz.
5. Hidrostatiese druktoets
Die hidrostatiese drukweerstand van die transducer moet nie minder as 0.5Mpa wees nie.

Rigting openingshoek
1.3. Hidrostatiese druk toets
Nadat die transducer aan 0.5MPa/1h, 0MPa/0.5h, 0.5MPa/1h en 0MPa/0.5h hidrostatiese druktoetse onderwerp is, is die isolasieweerstand tussen die positiewe en negatiewe elektrodes van die transducer groter as 200M Ω.
