Better: Test Using the TDT Test Block Submerged in Water
1. Place the Test Block in a shallow container such as a plastic storage bin (Figure 2).
2. Fill the container with enough water to cover the top of the Test Block by 2.5cm (1").
3. Carefully place the acoustic face of the transducer onto the Test Block.
4. Gently move the transducer from side to side to fully wet its acoustic face.
Be careful not to
agitate the water.
Air bubbles in the water will interfere with transmitting and receiving signals.
