Manual Zero Set; Acoustic Zero Set - Novatest ZBL-U5 Series Instruction Manual

Manual for ZBL-U5 series of Ultrasonic Detector

3.6.1 Manual zero set

After have read acoustic time on waveform, find out the option
of Zero acoustic time in parameter interface, and input the acoustic
time into it manually.

3.6.2 Acoustic zero set

1）Press the Zero button in parameter interface, input standard
acoustic time in pop-up dialogue box as shown in Figure
3.7(If use standard rod for zeroset, input the standard
acoustic time value of standard rod; if use coupling
transducer for zeroset, input 0).
2）Couple transducer according to the prompt message, press
Zero button to close this dialogue box, start sample
automatically, display waveform in waveform range and
search head wave automatically.
3） Adjust waveform in main interface, press Stop button to stop
sampling after have found head wave, and prompt message
of new tested zero acoustic time (As shown in Figure 3.8)
will pop up automatically, press Yes button to complete
zeroset; the current acoustic value is set as zero acoustic time,
which will be written into parameter file. Press No to cancel
this zeroset result.
