3. Use the [] or [] keys to respectively increase or decrease the blank value until
you exclude early unwanted echoes from detection.
The extended blank horizontal bar just above the waveform display indicates the
extended blank length (see Figure 10-2 on page 138).

4. To turn off the extended blank, use the [] key to decrease the extended blank
value back to zero.
If the measurement point changes when the extended blank is moved, echoes can
change in height. This is because in the normal waveform display mode, the
38DL PLUS attempts to adjust the height.
The instrument also attempts to make the most accurate measurement by identifying
the beginning of an echo. When the extended blank is positioned within an echo
instead of to its left, the gage is unable to make an accurate detection.
