To measure the position and size of flaw echo. DFD30 is equipped with double-gate function: Gate A and Gate B, normally Gate A is used alone for detecting the workpiece flaw, and the double-gate is usually used in the measuring and calibration of multi-echo, eg. Measuring the distance between surface echo and first echo during thickness measurement. - Page 13 Ultrasonic Flaw Detector DFD30 Under a GATE and b GATE, press up or down key to choose a THRESH and b THRESH, press + or – key to make change. Parameter ange: 3.5%-96.5% 5.2.4 a LOGIC and b LOGIC This menu is multipurpose for gate logic.

Ultrasonic Flaw Detector DFD30 5.4.1 MEAS There are two styles: PEAK and FLANK. PEAK: The detection occurs at the highest peak in the gate. FLANK: The detection occurs as teh first half cycle left edge rises and breaks the threshold. - Page 16 Ultrasonic Flaw Detector DFD30 Making of DAC curve 1． Please do caliration of Probe zero, X-value as well as K-value of angle beam. Acccording to specific condition, please do set the range, for example reference test block, take a hole of 10mm in depth and let the echo at the highest peak to be 90% full of screen.
