Remarks
• For the settings such as B/BA mode, Distance feed/Time feed, Absolute value gradation/Offset
gradation, Depth calibration value, and Sensitivity, see section 2.3 "Parameter Setting Screen."
• Automatic real-time surface wave processing may not eliminate all waves reflected by the
concrete surface depending on the conditions. If the peak processing of image processing is
performed in this state, waves reflected by reinforcing steel bars may become invisible.
The waves reflected by reinforcing steel bars can be displayed by the method explained in
section 3.2.5 "Manual real-time deduction processing" or section 3.4 "Image
processing."
• If the unit is moved too fast, a buzzer will sound. Data at the time is not displayed.
• Even if this unit moves in the direction opposite to the traveling direction, data will be displayed
on the assumption that the antenna moves in the traveling direction.
• The latest scan test data in B mode includes data about the antenna's center mark "
lower part of the case.
• The position of the fixed cursor on the B-mode display indicates the rear end of this radar, and it
can be used to identify the position of the reinforcing steel being scan tested. (See Figure 3-9
for the fixed cursor.)
