Relative permittivity setup
The relative permittivity setup is made by detecting an embedded steel bar with a known
covering depth or the wall with the known width and adjusting the relative permittivity value
so as to get the measured depth or width of the object matched with the known value.
This section provides the setup procedure using the wall with a known width.
(1) Confirm the wall width
Confirm the width of the wall by using the scale. Figure 6-1 shows an example of the width
140 mm.
Figure 6-1 Confirmation of the wall width
120
(2) Scan the wall
Scan the wall with the relative permittivity 8.0 of the sensor unit. For the procedure to set
the relative permittivity of the sensor, refer to Section 4.11.1 Device setting: [Relative
permittivity] menu)
The reflection wave from the opposite side of the wall appears on the main screen as the
shape of the horizontal band as shown in Figure 6-2.
Move the horizontal cursor on the edge of the horizontal band. The depth value of the
cursor is displayed in the cursor coordinate. (In the example of Figure 6-2, the depth is 127
mm.)
The reflection
from the wall is
shown as a
horizontal band.
Align the cursor
on the reflection
from the wall.
The depth value
of the cursor
shows the width
of the wall.

122
(4) Set the relative permittivity value.
Tap the value of the relative permittivity, then the list of the available values appears. When
the cursor depth is wider than the confirmed width of the wall, increase the relative
permittivity value. Decrease the value when cursor depth is narrower than the confirmed
width. (You can scroll the list upward and downward, and you can select a value in the
range from 2.0 to 20.0)
Adjust the relative permittivity value so as to get the depth value (measured width of the
wall) matched with the known value (the confirmed known width of the wall).
Set the relative
permittivity so
as to get the
depth value
same as the
known width of
the wall.
Figure 6-4 Relative permittivity setup
123
(5) Register the relative permittivity in the device setup screen.
Tap [□Applies to the measurement], then confirm a mark 9 is shown in the [□]. With
this, the relative permittivity value is registered to [Device setup: Relative permittivity]
menu in the parameter setup screen. Then tap [OK] to complete the relative permittivity
setup, then the screen returns to the main screen.
Figure 6-5 Relative permittivity setup
Caution
y When tapping [OK] without putting 9 into [□Applies to the measurement], the
new relative permittivity is applied only to the scan image displayed currently, but
not to the relative permittivity of the device setup which is used in scanning. The
next scanning is made by using the original relative permittivity in the [Device
setup: Relative permittivity] menu, but not using the new value defined in the
procedure above.

Procedure to mark the rebar
This product is equipped with a chalk guide at the front and rear edge of the sensor unit.
By using the chalk guide, you can easily mark the rebar position on the concrete during the
scan. The marking is made at the position where the fixed cursor position is matched with
the rebar position (peak of the inverse U shape shown in the B mode display). This section
describes the procedure to mark the rebar on the concrete.
6.2.1. Forward scan marking
When scanning forward, the chalk guide at the rear panel is used to mark the rebar
position.
Move the sensor unit so as for to superpose the rebar position (peak of the inverse U
shape shown in the B mode display) on the fixed cursor. Then mark a line on the concrete
along the rear chalk guide.
Adjust the sensor unit position to
superpose the fixed cursor on the
rebar position.
Make a line along the rear
chalk guide.
Figure 6-6 Forward scan marking
125
6.2.2. Backward scan marking
When scanning backward, the chalk guide at the front panel is used to mark the rebar
position.
Move the sensor unit so as to superpose the rebar position (peak of the inverse U shape
shown in the B mode display) on the fixed cursor. Then mark a line on the concrete along
the front chalk guide.
Adjust the sensor unit position to
superpose the fixed cursor on the
rebar position.
Make a line along the
rear chalk guide.
Figure 6-7 Backward scan marking
Note
y This product supports the back scroll capability. The marking can be made by
confirming the rebar position while moving the sensor unit forward and
backward.
y This product does not have the imitation of the scan distance. Therefore, you can
make the marking without considering the distance limitation. The scan data
shown on the main screen and saved into the file is maximum 15 m data of the
latest scan data from the scan stop point.
126
6.3.
AutoMark function
AutoMark is the function which automatically analyzes the scan data, detects the position
of the embedded object, and adds a marker on each of all detected objects. This function
improves the work efficiency of adding markers on the rebar position for the relatively
easily analyzable scan data (in which the detected objects has wide pitch and is located at
shallow area) at the field. This function is aimed to add markers on the rebar of the upper
level, so that this function may not add markers correctly on the cavity position or the
lower level rebar. (This function provides good detection performance for the rebar with the
cover width (depth) ≤ 100 mm and the rebar pitch ≥ 75 mm).
You can use this function with the procedure described below.
Caution
y AutoMark function provides a guide of detecting the rebar in the scan data. It may
cause wrong detection or detection failure of the rebar. After executing AutoMark
function, confirm the detected and added marker placed on the rebar in the scan
image visually. JRC assumes no liability for any damage (such as damage
caused to rebars, electrical pipes, gas pipes, etc.) arising from scan results
using this product.
y AutoMark function deletes all registered markers in the selected marker group
and executes the automatic detection. When you need to refer to the registered
markers later, save the scan result, then execute Auto Mark function.
Note
y AutoMark function can add maximum 99 markers for each marker group. When
the number of added markers reaches to 99, it does not add any markers for the
rest of the scan data.
y You can perform marker operations (addition and deletion) for the scan data after
AutoMark function is executed. Marker operations may make marker numbers not
sequential. In that case, you can re-number marker numbers to be sequential by
using Sort marker function. For Sort marker function, refer to Section 6.6 Sort
marker.
y When the measurement mode is set to time, AutoMark does not add markers
correctly on the rebar.
y AutoMark function does not detect the rebar located at very shallow area of the
depth (cover width) ≤ 1 cm.

Location notification function
Location notification function is the function available during the scan and assists to show
the rebar position by beeping and lighting the front and rear LED every time when the fixed
cursor is superposed on each marker position. This function is similar to and can be used
in addition to the AutoMark function which automatically analyzes the scan data, detects
the position of the embedded object, and adds a marker on each of all detected objects.
This function improves the work efficiency of adding markers on the rebar position for the
relatively easily analyzable scan data (in which the detected objects has wide pitch and is
located at shallow area) at the field.
This function is aimed to add markers on the rebar of the upper level, so that this function
may not add markers correctly on the lower level rebar or the rebar at the cavity position.
(This function provides good detection performance for the rebar with the cover width
(depth) ≤ 100 mm and the rebar pitch ≥ 75 mm).
You can use this function with the procedure described below.
Caution
y AutoMark function provides a guide of detecting the rebar in the scan data. It may
cause wrong detection or detection failure of the rebar. After executing AutoMark
function, confirm the detected and added marker placed on the rebar in the scan
image visually. JRC assumes no liability for any damage (such as damage
caused to rebars, electrical pipes, gas pipes, etc.) arising from scan results
using this product.
Note
y Location notification function works for the scan data of 1 m range from the final
scan position.
y All markers added by Location notification function are removed automatically
after the scan is completed. To detect rebars and add markers automatically after
the scan is completed, use AutoMark function described in 6.3 AutoMark function.
y Location notification function is not available when the measurement mode is set
to time.
y Location notification function does not detect the rebar located at very shallow
area of the depth (cover width) ≤ 1 cm.

Sort marker
Sort marker is the function which re-numbers ID numbers of all registered markers from
the search start point or from the search end point. Marker operations (deletion or addition)
may make marker numbers not sequential which is inconvenient in making a detection
report. By using this function you can easily get sequential ID numbers for all registered
markers.
This section provides an example using Sort marker to re-number non-sequential marker
ID numbers which is caused by adding a marker manually at the rebar not detected by
AutoMark function.
Cautio
Caution
y After executing Sort marker, you cannot restore the marker ID numbers into the
previous state. If you need to refer later to the scan data with the marker ID
numbers before sorting, save the scan data into the file and execute Sort marker
function.
Note
y When two markers are located at the same distance, Sort marker assigns the ID
number from the marker at the shallower area.
y Marker ID numbers obtained by Sort marker are reflected to the marker list and
the detailed marker list.

Theory
The principle of this product is basically the same as for general radars widely used at
present. Electromagnetic waves are transmitted from the antenna toward the concrete as
shown in Figure 8-1. The electromagnetic waves are reflected by an interface with the
reflecting objects (e.g., rebars or cavities) whose electrical property is different from that of
concrete. The waves are reflected back onto the surface of concrete and received by the
receiving antenna placed near the concrete surface. The distance to the reflecting objects
can be calculated from the time the reflected waves need to reach the receiving antenna.
The horizontal locations of the objects can be detected by moving the main unit on the
surface of concrete.
Since this product is designed to probe objects with high resolution that are near from the
surface of concrete, it transmits electromagnetic waves with the very narrow pulse width of
about one nanosecond (one-billionth of a second) or less.

（ｍ／ｓ）
Where
C: Velocity of electromagnetic waves in vacuum (in air) (3 × 108 m/s)
εr: Relative dielectric constant of concrete (2 to 20 in the example)

Applicable condition
(1) Applicable measuring conditions
(Waves reflected by objects to be scanned in reinforced concrete structures must be
received adequately, so the applicable measuring conditions vary slightly depending on
the on-site condition.)
Search depth (covering depth) within 0.5 to 30 cm (for concrete with a relative
dielectric constant = 6.2 everywhere and the top rebar of diameter ≧ 6mm)
Objects to be probed that are located at a depth of less than 75 mm have an interval
spacing of at least 15 mm.
For objects at the depth greater than 75 mm, the interval spacing of the objects is
more than the depth times 0.2.
Quality of concrete: Uniform
Direction of reinforcing steel: Orthogonal to this product's traveling direction
(2) Inapplicable measuring conditions
Scan of reinforcing steel or the like in concrete whose surface contains objects such
as metal that reflects radio waves
Presence of rebars that are parallel to this product's traveling direction
Objects has a narrow (pitch) arrangement for the interval of rebars in the horizontal
direction.
