The operation is performed as described below.
(1) Press the 6 PRCS key .
The inverted display is shown as the item for the PROC setting at the bottom of the screen
and operation switches to image processing.
(2) Set MAN (Manual) using the cursor keys ▲▼.
(3) Use the cursor keys
to move the cursor to a location where there is not a object to be
probed in the scan results. (See Figure 3-17 A)
(4) Press the 5 ENTER key. Manual surface wave processing will be performed while the
reflected wave at the cursor position is used as the surface wave. At this time, the marker ↓
is displayed at the previous cursor position. (See Figure 3-17 B.)
(5) To end the image processing mode, press the 6 PRCS key again.
The normal display is shown as the item for the PROC setting at the bottom of the screen and
image processing mode is exited.
• When MAN (Manual) is set with the cursor keys ▲▼ after manual surface wave
processing (including real-time manual deduction processing) and deduction processing,
image data will be displayed using manual surface wave processing that uses the surface
wave at the cursor position (indicated by ↓ ) of the last-executed processing. (Manual
surface wave processing can be newly performed by moving the cursor and pressing the 5
ENTER key.)
→ See Section 3.2.5 Real time manual deduction processing regarding the real time manual
deduction processing.
• If manual surface wave processing and deduction processing (including real time manual
surface wave processing) after scanning are not performed, the image does not change when
the cursor keys ▲▼ are used to set operation to MAN (manual).
(Manual surface wave processing can be performed by moving the cursor and pressing the
5 ENTER key.)
• To perform manual surface wave processing again, repeat steps (3) and (4).
• Manual surface wave processing and deduction processing are almost the same but have a
different depth processing range.
・Manual surface wave processing: area where the effect of surfaces waves is high
・Deduction processing: full search depth
→ See Section 3.4.5 Deduction processing regarding the deduction processing.
• When the real-time manual deduction processing is selected for the cursor line containing the
reflection wave from the targeted object (ex:rebar), this image processing has possibility of
producing unwanted noise on the display by the influence of this reflection wave signal from
the object.
