4.7.1. Relative permittivity and depth calibration
The relative permittivity is an object-specific coefficient showing the relationship between
the electromagnetic propagation speed in the air and scanned medium. This product
measures the time between the time of transmitting the signal and the time receiving the
signal reflected at the embedded object, then calculates the depth of the embedded object
by using the measured time and electromagnetic propagation speed determined by the
relative permittivity of the scanned medium Depending upon the relative permittivity
entered, this product can correct the depth scale on the scan screen. Therefore setting the
appropriate value to the relative permittivity is the key factor to get the accurate depth of
the detected object. For the theory of operation, refer to 8 Theory.
Depth calibration is performed by estimating the relative permittivity of the scanned
concrete and setting the value to the relative permitivity. When the relative permittivity of
the scanned concrete is known, enter the known value to the relative permittivity. For the
setting procedure, refer to Sections 4.7 [Relative permittivity] icon and 4.11.1 Device
setting: [Relative permittivity] menu.
To reduce depth error when the relative permittivity of the scanned concrete is unknown,
perform the depth calibration before the scanning with the following procedure.
(1) Scan the object whose actual depth is known (Ex. the rebar with a known depth or a
wall with the known width) and detect the depth of the object.
(2) Adjust the relative permittivity value so that the depth displayed in the scan result
matches with the known depth.
When the object with a known depth is not avaialble and the relative dielectric constant of
the concrete is unclear, it is recommended to set 8.0 (+0) as the relative permittivity.
Note
y The relative permittivity depends on the condition (such as moisture content) of
the concrete being scanned. Therefore the more difference between the actual
relative dielectric constant of the concrete and the entered value, the more the
depth error. Set an appropriate value to this parameter to get the accurate depth.

4.10.1. Image processing
The original scan data includes always unnecessary reflected signals (for example, the
reflection wave from the concrete surface (surface reflection wave) or reflection wave from
the boundary of concrete layers) which is commonly distributed over the scan image.
These unnecessary reflection waves make the image decoding difficult.
Image processing aims to remove or reduce the unnecessary reflection waves by data
processing (subtraction, averaging, and so on) and to provide easy deciphering of objects
that are being probed from the scan result.
This product supports the image processing listed in Table 4-2. Three image processing
can be performed in real time during scanning. The other image processing are
applicable to the scan result only at the idle state. Peak processing is applied to the image
data obtained by an image processing. Table 4-2 shows which image processing is
applicable in real-time during scanning and can be combined with the peak processing.
For the image processing applicable at the idle state, refer to Section 4.10 [Image
processing] icon. For the image processing applicable in real-time during scanning, refer
to Section 4.11.4 Device setting: [Image processing] menu.
This section describes the details of each image processing.

4.10.2 Fixed surface processing
4.10.2. Fixed surface processing
This image processing subtracts the predefined data of the typical concrete surface
reflection wave from the displayed scan data. Usually it can reduce the concrete surface
reflection wave to provide easy image decoding.
The predefined data used in this image processing is called the fixed surface reflection
wave which is generated at the factory by using typical concrete and is stored in the
non-volatile memory of the sensor unit.
Note
y The scan result file stored into the data storage contains the raw scan data, the
information about the selected image processing, and the fixed surface wave data
used for the image processing. When the data is recalled from the file, NJJ-200
application displays the scan image by using the recalled data (raw scan data, the
image processing setting, and the fixed surface wave data). After scanning,
NJJ-200 application displays the scan image obtained by performing the selected
image processing and the fixed surface wave data prepared in the sensor unit.
4.10.3. User surface processing
This image processing subtracts the user defined surface reflection wave from the raw
scan data. The user defined surface reflection wave is registered by selecting a point in the
actual scan data. Then this image processing subtracts the actual reflection wave selected
in the scan data, so that it can reduce the affection (noise) of the concrete surface
reflection wave more accurately than the fixed surface wave processing.
The user surface reflection wave can be defined and registered by the following
procedure.
(1) Scan the concrete. After the scan completed, the scan result image is displayed on
the screen.
(2) Move the cursor to the area on the scan result image where you want to do the
processing. Make sure not to put the cursor directly on the point with a reflection
signal (echo) from any embedded objects.
(3) Tap [Image processing] icon. Then the image processing setup screen appears.
(4) Tap User surface processing and confirm that the mark ● is attached to the
selected setting. Then tap [□Processed at the current cursor.] and confirm that a
mark 9is displayed in the [□].
(5) Tap [OK]. Then a message “Are you sure to update the user surface wave
data?” [Cancel] [OK] appears. Tap [OK].
(6) A message “Saving user surface wave data completed” appears. Then tap [OK]
to return to the main screen.

Note
y The data file in the data storage contains the raw scan data, the image processing
setting, and the fixed surface wave data used in the image processing. When the
data is recalled from the data file, the scan result image is displayed by using the
recalled data (raw scan data, the image processing setting, and the fixed surface
wave data). However, the NJJ-200 application will displayany newly scanned
images by using the image processing and the fixed surface wave data prepared
in the sensor unit’s settings.
y You can register a point in the recalled scan result as the user surface wave. After
recalling the scan result, perform the procedure above to register a point of the
recalled scan result as the user surface wave.
y When the point showing some reflection signal from the embedded object is
registered as the user surface wave, the image processing may produce
unwanted noise on the scan result image.
y When the unwanted noise appears after the image processing, register a different
point with no reflection signal on the scan result as the user surface wave.
58
4.10.4. Subtraction
This image processing is used to reduce the horizontal band noise of the reflection wave
appearing at the depth more than 20 cm as shown Figure 4-16 1). You can use this image
processing with the procedure below.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the
main screen.
(2) Move the cursor to the area on the scan result image where you want to do the
processing. Make sure not to put the cursor directly on the point with a reflection
signal (echo) from any embedded objects.
(3) Tap [Image processing] icon. Then the image processing setup screen appears.
(4) Tap [Subtraction] and confirm that the mark ● is attached to the selected setting.
Then tap [□Processed at the current cursor.] and confirm that the mark 9is
displayed in the [□].
(5) Tap [OK] to return to the main screen.
Here NJJ-200 application executes the subtraction processing by using the data specified
at the step (2) above and shows the image after the processing. (The label of [Image
processing] icon shows SUB.) The mark È is shown at the point selected as the
subtraction data on the distance scale.

Note
y When tapping [OK] without the mark 9 at [□Processed at the current cursor]
at the step 4) above, a message “No processing point defined” appears and
the processing is canceled.
y When re-executing the manual surface wave processing or the subtraction
processing (including real-time manual subtraction processing) without the mark
9 at [□Processed at the current cursor], the processing is executed by using
the reflection wave data previously registered and shown by the cursor mark È on
the distance scale. To change the reflection wave data used for the processing,
perform the steps 2) to 4) above.
y For the real-time subtraction processing, refer to Section 3.4 Interpreting the scan
result.
y The processing of the manual surface processing is almost same as that of the
subtraction processing. The difference is that the manual surface processing
subtracts the surface reflection wave data from the scan result only for the depth
range of 0 mm to 200 mm. The subtraction processing subtracts the surface
reflection data from the scan result over all depth range.
y The subtraction processing may remove the reflection wave from the opposite
side of the concrete wall.
y For the manual surface processing, refer to Section 4.10.5 Manual surface
processing.
y When the registered surface reflection wave contains some signal reflected from
the embedded object, the processing may produce the unwanted noise.

4.10.5. Manual surface processing
This image processing is used to reduce the remained noise even after an image
processing (Refer to Figure 4-17 1)) . This image processing subtracts the registered
surface reflection wave from the scan result only for the depth range of 0 mm to 200 mm.
You can perform this image processing with the following procedure.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the
main screen.
(2) Move the cursor to the area on the scan result image where you want to do the
processing. Make sure not to put the cursor directly on the point with a reflection
signal (echo) from any embedded objects.
(3) Tap [Image processing] icon. Then the image processing setup screen appears.
(4) Tap Manual surface processing and confirm that the mark ● is attached to the
selected setting. Then tap [□Processed at the current cursor.] and confirm that the
mark 9is displayed in the [□] .
(5) Tap [OK] to return to the main screen.
Here NJJ-200 application executes the manual surface processing by using the reflection
wave data specified at the step (2) above and shows the image obtained by the
processing. The label of [Image processing] icon shows MNL. The mark È is shown at
the point selected as the subtraction data on the distance scale.

Note
y When tapping [OK] without the mark 9 at [□Processed at the current cursor]
at the step 4) above, a message “No processing point defined” appears and
the processing is canceled.
y When re-executing the manual surface processing or subtraction processing
(including real-time manual subtraction processing) without the mark 9 at [□
Processed at the current cursor], the processing is executed by using the
reflection wave data previously registered and shown by the cursor mark È on the
distance scale. To change the reflection wave data used for the processing,
perform the steps 2) to 4) above.
y For the real-time subtraction processing, refer to Section 3.4 Interpreting the scan
result.
y The processing of the manual surface processing is almost same as that of the
subtraction processing. The difference is that the manual surface processing
subtracts the surface reflection data from the scan image only for the depth range
of 0 mm to 200 mm. The subtraction processing subtracts the surface reflection
data from the scan result over all depth range.
y The subtract processing may remove the reflection wave from the opposite side of
the concrete wall.
y For the manual surface wave processing, refer to Section 4.10.5 Manual surface
processing.
y When the registered surface reflection wave contains some signal reflected from
the embedded object, the processing may produce the unwanted noise.

4.10.6. Averaging
This image processing is effective to reduce the horizontal line noise appearing uniformly
over the scan result. It subtracts the averaged wave of all scan points from the scan result
and displays the processed image. This processing may remove the continuous reflection
signal appearing at the constant depth like the reflection from the opposite side of the
concrete wall. Use this processing by considering this point.
You can perform the average processing by the following procedure.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the
main screen.
(2) Tap [Image processing] icon. Then the image processing setup screen appears.
(3) Tap Averaging and confirm that the mark ● is attached to the selected setting.
(4) Tap [OK] to return to the main screen.
Here NJJ-200 application executes the average processing and shows the image
obtained by the processing. The label of [Image processing] icon shows AVG.

Caution
y This processing reduces the horizontal line noise appearing uniformly over the
scan result, so that it may remove the similar image of the continuous reflection
signal appearing uniformly at the constant depth like the reflection from the
opposite side of the concrete wall.
63
4.10.7. Peak processing
This image processing is effective to remove the unwanted image caused by the ringing in
the reflection wave from the detected object (steel bar) and to show the refection wave
only from the detected target. Use this processing when the depth of the detected object is
difficult to read due to the images of the ringing. This processing is not applicable to the
detection of the object (ex. cavity) with the relative permittivity lower than that of the
concrete. This processing is applicable to the processed image obtained by fixed surface
wave processing (including real-time surface wave processing), average processing,
subtract processing, manual surface wave processing, user surface wave processing, or
the original image.

(The shape of the [Save/Print] icon becomes a printer when the printer is selected.)
After tapping [File/Print] icon, NJJ-200 application searches the available printer and after
detecting a printer, it starts to print out. Then a message “Printing…” [Cancel] appears.
Here you can cancel the print out by tapping [Cancel] . After completing the print out, the
message disappears.
The printed scan data is from the scan image displayed on the main screen from the start
point of the scan data. When you want to print out all of the scan data, scroll the scan data
to the end of the scan data and then start the print out.

117
When the Smartphone cannot detect an available printer (ex. When the printer is not
turned on.), a message “Could not establish the communication with a printer.” [OK]
appears. In this case, confirm that the printer is turned on.
When Bluetooth pairing of the Smartphone and the printer is not completed, a message
“The printer is not paired. I will finish printing.” [OK] appears. In this case, shut down
NJJ-200 application and perform Bluetooth pairing in accordance with
Section 5.8.2 Bluetooth pairing.

2)Bluetooth pairing not made
Figure 5-13 Example of printing failure
Caution
y Before printing out, the printer setup is required. Make sure to complete the printer
setup described in Section 5.8.1 Preparation for the printer.
y The printer is dedicated to NJJ-200 Handy Search. It is not applicable to the any
other Handy Search model.
y Make sure one Smartphone is paired to only one printer for Bluetooth pairing.
Smartphone does not allow you to select one from some available printers. The
scan data is printed out to the printer detected by Smartphone first of all.
y The print out is made in monochrome of 16 gradation). The printed image is not
the same as that of the scan image displayed on Smartphone.
y The print out of the scan data is compressed to fit for printing. Although the
position of the cursor and marker may be slightly moved on the print out, however,
the coordinate information of the cursor and marker is not changed.
y Make sure to use the recommended print paper.
118
Note
y For detailed information about the printer, refer to the printer manual. The range of
printing is from the scan start point (0 m) to the scan image displayed on the main
screen. To print out all the scan data, scroll the main screen to the end of the
scan position and print out the scan data.
y The direction of printing depends on the scan direction (forward or backward).
y The speed of printing slows down in accordance with the battery voltage of the
printer. Change the battery as soon as possible when the speed of printing out is
slowing down.
y When a message “Low printer battery voltage. “ [OK] during printing or at the
start of printing appears, it means that the battery voltage of the printer is dropping.
Turn off the printer and change the battery with a fully charged one.
y When a message “No print paper. Turn off the printer and supply the paper
to the printer.“ [OK] during printing or at the start of printing, the printer is in out of
paper. Turn off the printer and supply the print paper. (If the paper was supplied
when the printer is turned on, the next print out will not be executed correctly. In
this case, cancel the print out, and cycle the power of the printer.)
y For the scan data of the distance more than 10 m scanned with the distance
correction ≥ 13, when printing it in Wide (“W”) view range (Shallow W, Normal W,
Depth W), the printed image may be difficult to recognize.
