Adjusting the Delay Value

The delay of the waveform display adjusts the beginning of the horizontal span. The
delay can be adjusted to display the waveform of interest in the center of the
waveform display. This function is very useful when using delay line or immersion
transducers, or when measuring thick material, in order to ensure that the measured
echoes can be seen in greater detail.
To adjust the delay value
 In the measurement screen, press the [] and [] keys to adjust the delay.
