Adjusting the Delay Value

The delay of the waveform display adjusts the beginning of the horizontal span. You
can adjust the delay 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 so that the measured echoes can be seen in greater
detail.
To adjust the delay value
1. Press [2nd F], [RANGE] (DELAY).
2. Use the arrow keys to adjust the delay value.
3. Press [2nd F], [RANGE] (DELAY) again to stop editing the delay value.
TIP
Press and hold the [RANGE] key to reset the delay to zero.

Activating the Zoom Function

The zoom function automatically and dynamically sets the delay and the range values
to optimally track and show the detected echo in the waveform display.
To activate the zoom function
1. From the measurement screen, press [ZOOM].
The zoom flag ( ) appears on the right side of the waveform display, below the
power indicator.
2. Press [ZOOM] again to turn off the zoom function.
The resulting zoomed waveform depends on the current measurement mode. The
zoom for D79X dual element transducers and mode 1 single element transducers
centers the first back-wall echo on the screen (see Figure 4-8 on page 59).
