Zero Set - Novatest ZBL-U5 Series Instruction Manual

Manual for ZBL-U5 series of Ultrasonic Detector
1) Move cursor left and right
Press 【 】 or 【 】 buttons to move vertical (acoustic time)
cursor and display acoustic time value at cursor position in cursor
parameter area.
2) Move cursor up and down
Press 【 】 or 【 】 buttons to move transverse (amplitude)
cursor and display acoustic time value at cursor position in cursor
parameter area.
3) Move waveform left and right
Press Wave ←and Wave →buttons to move waveform left
and right.
4) Save the manual interpretation result
After have located the transverse (amplitude) and vertical
(acoustic time) cursors, press Save button on operation panel to
save cursor determining result, which means use the acoustic time
and amplitude values at cursor position to replace the acoustic
time and amplitude values of current test point.
5) Close the operation panel
Press any areas outside of single-channel waveform range to
close operation panel.

3.6 Zero set

Zero acoustic time refers to the acoustic delay between ultrasonic
instrument and transmitting and receiving transducers; zero acoustic
time must be eliminated in testing acoustic time value. Zero set
obtains zero acoustic time through test. This operation is required
when operate ultrasonic instrument and replace transducer or signal
wire in the first time.
