Calibrating the EPOCH 1000 Series (Phased Array Mode) 291
5.
Move the probe forward and backward to bring the echo to its maximum
amplitude (peak). Ensure that the echoes do not exceed 100 %. Reduce the gain
setting if necessary.
6.
Use the
[GATE]
key to position gate 1 around the first back-wall echo.
If it is unclear from the S-scan, use the A-scan to position the gate start and width
positions so that only the first back-wall reflection is in the gated region.
7.
Use the
[GATE]
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 4 in. (100 mm).
8.
Adjust the gain so that the echo amplitude is at approximately 80 %.
A thickness measurement reading appears in large text as shown in Figure 17-13
on page 291.
