You can also apply the
Ref Correct
(reference correction) option to the digital
analysis of the live A-scan and DAC/TCG mode. The reference correction feature,
when activated, allows full gain manipulation of either the live echo peaks or the
DAC curve while providing the % amplitude or dB comparison of the actual
peak-to-curve ratio. In this way, you can use scanning gain while maintaining an
accurate measurement reading of the ratio of the gated peak to the DAC curve for
sizing purposes. The gated echo amplitude is corrected back to the reference gain
level for amplitude evaluation compared to the DAC curve.
4.
If applicable, set
Ref Correct
to
On
.
