Chapter 2 Functions, features, and parameters of the instrument
2.1 Basic functions of the instrument
Wave peak memory:
real time envelopes show the highest wave of the flaws and record the
maximum value of the flaws, it is helpful to position the flaws precisely and scan the work piece quickly.
With the help of envelope waveform, the quality of the flaws can be determined.
Automatic gain:
automatically adjust the gain to the preset amplitude height
Alarming function:
afferent echo/echo loss alarming
Real-time clock:
automatically record and store the date and time of waveforms
Display freezing:
catch waveforms and sound path data at any moment, and the gate can be moved
after freezing to measure the echo parameters
Flaw positioning:
real-time display sound path S, horizontal X, depth Y, and wave height H
Digital Reject:
0-80%, increase by 1%, unaffecting the linearity and gain
Wave height reading:
three display modes, namely relative wave height, dB difference relative to
the gate, and dB difference relative to DAC curve
Data communication:
communicate with the computer through RS232 port to transmit waveforms
and data so as to manage the result of detection on the computer, and generate the flaw detection reports,
