Signal source is stated to be connected with the oscillograph；
Keep the waveforms amplitude on the oscillograph maximum Step 3: translating the transmitting transducer, and records amplitude；
Step 4: amplitude size is stablized, then the reception energy converter if the sinusoidal impulse waveform of the oscilloscope display is undistorted
Battle array is working properly, on the contrary then be judged to cisco unity malfunction.
Optionally, it is described receive transducer array radiating surface level upward.
Optionally, the radiation face contact of the radiating surface for receiving transducer array and the transmitting transducer.
Optionally, after transmitting transducer being placed on the reception transducer array, the detection receives transducer array
Method further include:
