2. Manipulate the probe until a high-amplitude signal appears on the screen after
the excitation pulse.
This is the reflection from the large arc of the block that is located on the Type I
block at 100 mm (4.00 in.).
3. Move the probe forward and backward to bring the echo to its maximum
amplitude (peak).
4. Ensure the echoes do not exceed 100 %. If necessary, reduce the gain.
The peak memory is an excellent tool for finding the BIP. Press PEAK MEM to turn
peak memory on. This feature draws and collects the echo envelope of the signal
while also drawing the live waveform (see Figure 9-17 on page 167). Match the live
waveform with the maximum point corresponding to the previously accumulated
echo dynamic curve. Press PEAK MEM again to turn peak memory off.
