Standard/ASME III DAC/TCG

The Standard DAC mode is a single DAC curve drawn from peak-to-peak on
reference-reflectors. The ASME III (or ASME-3) mode draws three DAC curves: one
main curve from peak-to-peak on the reference-reflectors and two warning curves at
−6 dB and −14 dB compared to the main curve.
To set up ASME-3 DAC mode
1. Choose either Standard or ASME-3 on the DAC/TCG setup page.
2. Press to return to the live A-scan screen.
3. Set the range so the first reflector of the DAC curve is toward the left side of the
screen (see Figure 11-3 on page 229).
