• Yana ba da keɓewar makamashi da sigina tsakanin wurare masu haɗari da aminci.

5. Shirya matsala & Maintenance

• Babu Fitarwa ko Ƙarƙashin Ƙarfafawa: Duba ƙarfin wutar lantarki da ƙarfin lantarki; duba don bude kewaye a cikin madauki; duba lalacewar kebul na transducer.

• Cikakkun fitarwa (> 20.5mA ko <15.5mA): Bincika idan transducer yana kusa da ko taɓa abin da ake nufi; duba ga mummunan gurɓata ko lalacewa ga tip transducer; bincika babban bambanci tsakanin kayan da aka yi niyya da kayan daidaitawa.

• Hayaniyar sigina mai wuce gona da iri: Bincika amincin garkuwa da gyara ƙasa mai maki ɗaya; duba idan igiyoyin sigina suna tafiya daidai da igiyoyin wuta; duba don sako-sako da haɗin kai.

• Kulawa na yau da kullun: Yayin dubawa, bincika ƙarfin transducer da yanayin kebul; lokaci-lokaci tsaftace mai / man shafawa daga tip transducer; Za'a iya sake gwada aikin tsarin a lokacin manyan canje-canje.
