2.
Couple the transducer to the calibration block so that the BIP is directly over the
0 mark on the ASTM test block. Do not move the transducer from this point
during the distance calibration step.
3.
Use the G1Start button (P5 key) to position gate 1 so that the first reflection from
the arc of the block is exceeding the gate threshold.
This reflection should be close to 100 mm (4 in.).
4.
Press dB, and then adjust the gain setting so that the echo amplitude is at
approximately 80 %.
The AUTO XX% can be used to automatically adjust the gain to set the gated echo
amplitude to XX% of full screen height (the default XX value is 80 %). To activate this
feature, press 2
ND
F, (AUTO XX%).
The sound path measurement reading appears in the Reading 2 box (see
Figure 9-20 on page 170).
