relevant prompt will be shown on the bottom;<0}

3.5 Waveform display and operation
Single-channel waveform range is used to display the waveform
and acoustic parameters, etc. of current testing point as shown in
Figure 3.4. The bottom horizontal row of single-channel waveform
range for strength test, defect test and crack test displays acoustic
parameter and zero acoustic time value of head wave, the lower left
corner displays series number of test point, top left corner displays
delay time, as shown in Figure 3.4b.
The vertical progress bar at the right of single-channel waveform
means the gain; when gain is increasing, the progress bar ascends and
when gain is decreasing, the bar descends.
1)
Acoustic time value T: Transmission time of ultrasonic from
transmitting transducer to receiving transducer, the unit is μs,
this acoustic time value has deducted the system zero
