1) Meel dhaanta rari.

2) Isku day inaad nadiifiso dusha sare ee tuubada, oo aad isticmaasho isku xidhka ku filan si aad u kordhiso xoogga calaamada.

3) Ku hagaaji meelaynta transducer si toos ah iyo toosan;Hubi in kala dheeraynta transducers ay la mid tahay qiimaha M25.

4) marka walxaha tuubada aysan ku habooneyn gudbinta calaamadaha ultrasonic;transducer-kayaga kulul ee galinta ayaa lagula taliyay.
