Ukuba ixabiso lamandla esignali u-Q oboniswe kwi-M90 lingaphantsi kwama-60, kucetyiswa ezi ndlela zilandelayo ukuze uphumelele:

1) Fudukela kwenye indawo engcono.

2) Zama ukupolisha umphezulu wangaphandle wombhobho, kwaye usebenzise i-coupling compound eyaneleyo ukwandisa amandla esignali.

3) Lungisa indawo ye-transducer ngokuthe nkqo nangokuthe tye; qiniseka ukuba isithuba se-transducers siyafana nexabiso le-M25.

4) xa izinto zombhobho zingafanelekanga ukuhanjiswa kwesignali ye-ultrasonic; kucetyiswa i-transducer yethu yokufaka ene-hot-topped.
