2. Description

2.1 Purpose

The PS 200 Ferroscan system is designed to be used
for localizing steel reinforcing bars and determining their
diameter and depth of cover.

2.2 Overview

The appliance can be used for various concrete rein­forcement detection applications. The scanning mode
used depends on the application. These fall broadly into
the following categories:

Application

Avoiding hitting reinforcing
bars when hammer drilling
or coring

Determining the position/
number and diameter of
reinforcing bars for checking
loading capacity

Determining depth of cover
over large areas

2.3 Operating principle

The system functions by running the scanner directly
over the surface of the structure. The data collected is
stored in the scanner until it can be transferred to the
monitor. The monitor is used for storing large amounts
of data, viewing the scans and also for evaluation of
results. The data can also be downloaded to a PC. The
PC software offers advanced evaluation options, data
archiving functions and the ability to quickly print out
complete reports.

2.3.1 Quickscan detection

The scanner is run over the surface perpendicular to the
reinforcing bars. The position and approximate depth
of the reinforcing bars can be determined and marked
on the surface of the concrete.

2.3.2 Quickscan detection with accurate
determination of depth of cover

Before scanning, the operator is required to enter values
for the diameter of the reinforcing bars and the spacing
between the bars. The scanner is then used as described
in "2.3.1 Quickscan detection".

2.3.3 Quickscan recording

The scanner is used as in described in "2.3.2 Quickscan
detection". The data, however, is recorded while the scan­ner moves over the surface. This data is then transferred
to the monitor where it can be evaluated and the average
depth of cover determined. If the data is downloaded to
a PC, this information can be evaluated, archived and a
report printed. Enhanced evaluation options allow Quick­scans to be imported and evaluated automatically.

2.3.4 Imagescan

A reference grid is attached at the area of interest using
the adhesive tape supplied. After selecting the Image­scan mode with the scanner, the rows and columns of
the grid are scanned following the instructions on the
screen. The data is transferred to the monitor where the
image can be viewed and evaluated. The position of the
reinforcing bars relative to the concrete surface is indi­cated. The diameter of the bars and the depth of cover
can be determined.

If the data is downloaded to the PC application, this infor­mation can be evaluated as on the Ferroscan monitor,
with the additional advantage of allowing a series of
points to be recorded along with associated depth and
diameter, archived and a report printed.

2.3.5 Blockscan

A reference grid is attached at the area of interest using
the adhesive tape supplied. After selecting Blockscan
mode, the user is prompted to select the first area to
scan. An Imagescan is then made. After completing the
Imagescan, the user is prompted to select the next area
to scan. This should be adjacent to the previous area.
Move the grid and then scan as before. This procedure
can be repeated for up to 3 ×3 Imagescans.The data is
transferred to the monitor. The Imagescans are auto­matically stitched together to form a larger image. The
reinforcement layout can then be viewed over the whole
area. Individual Imagescans can be selected for evalu­ation by "zooming in".

If the data is downloaded to the PC application, this
information can be evaluated as on the Ferroscan mon­itor, with the additional advantage of allowing a series
of points to be recorded along with associated depth
and diameter, archived and a report printed.

6. Operation

6.1 PSA 80 battery

Charge both batteries using the PUA 80 chargers. Full
instructions are contained in the PUA 80 charger oper­ating instructions. Before first use, the batteries must
be charged for 14 hours continuously.

6.1.1 Inserting and removing the battery

Check that the battery is correctly aligned with the scan­ner or monitor as shown below.

Scanner – With the battery end cap facing you, the large
groove on the battery should be on the left.

Monitor – With the battery end cap facing you, the large
groove on the battery should be on the right.

Push the battery into the opening as far as it will go. Turn
the end cap clockwise until it slots into place and snaps
tight. To remove the battery, turn the end cap anti-clock­wise as far as it will go. Withdraw the battery from the
scanner or monitor.

7. Operation

7.1 Carrying and using the system

The scanner can be used without the monitor for scan­ning, or the monitor can be carried in the PSA 61 soft
pouch on the PSA 60 shoulder belt. The first option is
advantageous when working in areas that are difficult
to access and maximum mobility is required, such as
on a scaffold or ladder. When the scanner memory is
full (9 Imagescans made, 1 complete Blockscan or 30 m
of Quickscan have been recorded), the user must return
to the monitor to transfer the data. The monitor can be
kept nearby (e.g. at the foot of the scaffold, in a vehicle,
in the site office etc.). When the user intends to make
more scans than the scanner is capable of storing in its
memory and wishes to avoid repeated journeys to the
monitor, the monitor can be attached to a belt or carried
using the shoulder strap supplied.

-CAUTION-

The temperature inside a vehicle that is left exposed to
the heat of the sun can easily exceed the maximum stor­age temperature for the PS 200. Damage to one or more
components of the PS 200 may occur if it is stored in
temperatures exceeding 60 °C or 158 °F.

This may result in permanent data loss. Data that has
not been transferred to the monitor will be permanently
deleted.

Press the Down arrow button and then the Confirm

button to delete data. Alternatively, press the Cancel
button to return to the Settings menu.

7.2.5 Quickscan

Quickscan can be used to quickly detect bar positions
and depths that are then subsequently marked on the
surface. This is procedure is named Quickscan detec­tion.
Accurate depth measurement is another Quickscan func­tion in which values for bar diameter and bar spacing
must be previously entered.
Alternatively, the data can be recorded and evaluated on
the monitor or in the PC application.In this way, the aver­age depth of cover over the reinforcement over large
stretches of the surface can be easily determined. This
is termed Quickscan recording.

-CAUTION-

The scanner only detects reinforcing bars that lie per­pendicular to the direction of travel. Bars that lie parallel
to the direction of travel will not be detected. Therefore,
ensure that the object is scanned in both the horizontal
and vertical directions.
An incorrect depth may be calculated for bars that lie diag­onal to the direction of travel.
Switch on the scanner. The Quickscan icon is automati­cally the first selected.

Select Quickscan from the main menu.

The Quickscan screen is then displayed.

1 – Bar depth
2 – Distance traveled
3 – Signal strength
4 – Settings: minimum depth, scan direction, bar

diameter, bar spacing

7.2.5.1 Quickscan detection

Move the scanner over the surface. Reinforcing bars that
lie perpendicular to the direction of travel will be detect­ed. The distance covered by the scanner is recorded.

When approaching a reinforcing bar, the signal strength
increases and depth values may appear in the display.
When at the center of a reinforcing bar:

– the red LED lights,
– the scanner beeps,
– the signal strength bar is at maximum,
– and the approximate depth of the bar is indicated

(lowest depth value indicated = center of the bar).

The bar is positioned along the center line of the scanner
and may be marked on the surface using a PUA 70 mark­er. The accuracy of the depth measurement can be increased
by switching to accurate depth measurement measuring
mode. Please refer to section 7.2.5.2.

This symbol may appear when the scanner is moved over
the surface. It indicates that the scanner is being moved
too quickly to be able to process all signals generated. The
maximum speed is 0.5m/s (20 inches/sec.). If the symbol
appears during Quickscan detection, press Confirm and
scan again.

7.2.5.2 Quickscan with accurate depth
measurement

The measuring mode "Quickscan with accurate depth
measurement" is selected by pressing the Confirm but-
ton.

The diameter must be known and previously entered.

In addition, the value for the spacing between bars must
also be entered if it lies between >36 and <120 mm.

-NOTE-

Bar spacing of 36 mm or less cannot be measured.

This can be calculated automatically using the Quickscan
detection function by searching for the center of the bar
and pressing the red Record button when the scanner
is over the mid point of the bar. Next, search for the mid
point of the next bar and again press the Record but-
ton. Bar spacing is then calculated automatically and
recorded. If the spacing is known, the value can also be
entered manually.

After setting the bar diameter and bar spacing, the scan­ning procedure is identical to the procedure described
at 7.2.5.1.

7.2.5.3 Quickscan recording

To record the position and depth of all reinforcing bars
detected, place the scanner on the surface and use
Quickscan detection to find a position where there are
no bars present. Mark the starting point with a PUA 70
marker and press the Record button. The diskette sym­bol appears on the screen, indicating that the scanner
is recording data. Move the scanner over the surface.

At the end of the scan, take care to ensure that the end
point is not directly over a rebar. To stop recording, press
Record again. Use a PUA 70 marker to mark the end of
the stretch that has been scanned.

-NOTE-

Reinforcing bars that lie perpendicular to the direction
of travel will be detected and automatically recorded.
Ensure that the settings are correctly set before begin­ning recording.

-WARNING-

Always carry out an Imagescan prior to Quickscan record­ing in order to:
– establish the direction of the uppermost layer of rein-

forcement,
– minimize the risk of measuring on a spliced bar,
– and immediately see if there are any ferrous materials

in the concrete that may affect the accuracy of the result.

-CAUTION-

Do not press Record before placing the scanner at the
point where the scanning should begin. Failure to do
this may result in incorrect or misleading measurements.
Up to 30 m (98 ft) can be recorded before it is neces­sary to transfer the data to the monitor. It is also possi­ble to record several separate stretches (max. 10) that
add up to a maximum of 30 m.

49

en

-WARNING-

Do not remove the scanner from the surface before stop­ping the recording or setting a marker. Failure to do this
may result in incorrect or misleading measurements. For
information on setting a marker, refer to section 7.2.5.5.

This symbol may appear when the scanner is being
moved over the surface. It indicates that the scanner is
being moved too fast and it is unable to process all the
signals generated. The maximum scanning speed is

0.5 m/s. If the symbol is displayed while recording a
Quickscan, press the Confirm button. You will need to
begin the recording operation again from the original
starting point or from where the last marker was set.

The data may be transferred to the monitor. Refer to sec­tion 7.4.

7.2.5.4 Quickscan settings

The Quickscan settings are shown on the left hand side
of the display. The settings can be made before making
a Quickscan or a Quickscan with accurate depth mea­surement. Use the Arrow buttons and Confirm to access
the setting.

Minimum depth

Use this setting when scanning a surface and looking
specifically for bars that are located above a certain
depth. For example, if checking for 40 mm minimum
depth of cover, set the value to 40 mm. (For quality
assurance measurements add an extra 2 mm to account
for any accuracy limitations). The LED will light only if
a reinforcing bar lying within 40 mm of the surface is
detected.

Select the minimum depth function using the Arrow but-
tons and then press Confirm.

Setting minimum depth

Minimum depth function disabled

When the value is set to 0, the function is deactivated
and appears as above. Enter the required minimum depth
using the Arrow buttons. Press Confirm to make the set­ting. The system returns to the main menu.

Scan direction

This setting is used to set the direction in which Quick­scan recording is performed. Although it has no direct
effect on any measurement values subsequently con­tained in the monitor or PC application, it helps to match
the resulting chart and depth values in the PC applica­tion with the actual structure surface. The scan direc­tion will be saved with all Quickscan recordings.

Select the direction in which the scan is to be performed

7.2.5.5 Setting a marker

When recording, the surfaces of many structures con­tain obstacles that prevent the scan being recorded
without lifting the scanner from the surface. Examples
of such obstacles are piers or columns in a wall, door
openings, expansion joints, corners etc.

If an obstacle is encountered, a marker may be set. This
interrupts the scan and allows the user to safely remove
the scanner from the surface, place it beyond the obstruc­tion and then continue scanning. It also indicates where
certain objects are located within a scan, providing addi­tional information for referencing the scan data to the
actual surface.

To set the marker press and hold Confirm, whilst in
recording mode. The diskette symbol will be crossed
out, indicating that recording has been suspended and
a marker has been set.

Then lift the scanner from the surface whilst still hold­ing the Confirm button depressed. If necessary, mark
the position on the surface using a PUA 70 marker. Place
the scanner back on the surface beyond the obstacle,
release Confirm and continue scanning. The marker will
be shown as a vertical line in the scan data when viewed
on the monitor or in the PC application.

-CAUTION-

De to interruption of the recorded signal, scanning results
are less accurate immediately before and after the point
where a mark is made.

7.2.6 Imagescan

Imagescan is used to create an image of the reinforce­ment layout. The depth and diameter of the bars can be
determined.

Firstly, a PSA 10 or PSA 11 reference grid has to be fixed
to the wall. Use the adhesive tape supplied. This tape is
designed specifically for sticking to concrete structures
and can be torn off the roll by hand at the correct length.
For most surfaces, a 100 mm (4 inch) piece of tape at
each corner is adequate to secure the grid. Particularly
moist or dusty surfaces may require a length of tape
along each side of the grid.

Alternatively, a grid can be marked directly on the sur­face. Using a straight edge (such as a piece of wood) as
a guide, mark a 4 ×4 grid with 150 mm spacing between
the parallel lines.

Switch on the scanner. Move to the Imagescan symbol.
The battery level is displayed together with the number
of Imagescans currently held in the memory out of a
maximum of 9.

Select Imagescan from the main menu.

The Imagescan screen is displayed.

A representation of the grid appears on the screen with
a suggested starting point. This is always upper left and
will suffice for most scans. Image data will only be gen­erated for areas of the grid that have been scanned both
vertically and horizontally. In some cases, obstacles on
the scan area may prevent this (e.g. a pipe penetrating
a beam). The starting point can then be changed to opti­mize the area scanned in such a case. Use the Arrow
buttons to change the starting point.

51

en

Place the scanner on the grid at the starting point shown
by the blinking arrow. Ensure the alignment marks on the
scanner are aligned correctly with the grid as shown below.

-NOTE-

Incorrect alignment of the scanner on the grid may lead
to the bar positions being incorrect on the generated
image.

Press Record and move the scanner along the first row.
Progress when scanning is shown by a thick black line
which advances on the display as the scanner is moved
over the surface.

The scanner will emit a double beep at the end of the
row, automatically stopping the recording. Repeat the
process for each row, observing the prompts on the
scanner display telling you to begin a new line.

When all rows are complete, scan the columns in a sim­ilar way.

The recording of any row or column may be interrupt­ed before reaching the end by pressing Record again.
This may be required if an obstacle prevents scanning
of the full path. Similarly, an entire row or column may
be skipped by starting and stopping the recording with­out running the scanner over the grid.

Note that no image will be created for areas of the grid
that are not scanned in both directions.

It is possible to repeat the previous row or column by
pressing Cancel. This may be necessary if the user is
not sure that the scan field has not been followed accu­rately. Pressing Cancel a second time aborts the scan
and returns to the main menu.

This symbol may appear when the scanner is being
moved over the surface. It indicates that the scanner is
being moved too quickly to allow it to process all the
signals generated. The maximum speed is 0.5 m/s or
20 inch/s. If this symbol appears, press Confirm and
repeat the row or column you were scanning. In all cas­es, move the scanner more slowly over the surface.

When the scan is complete, press the Confirm button
to return to the main menu. The data may be transferred
to the monitor for viewing and evaluation. Please refer
to section 7.4.

-CAUTION-

Pressing the Cancel button causes the recorded Images­can to be deleted. The screen then returns to the main
menu.

7.2.7 Blockscan

Blockscan automatically stitches Imagescans together
to give an impression of the reinforcement layout over
a large area. The exact bar position, depth and diame­ter can also be determined on the monitor by selecting
each Imagescan individually.

Attach the reference grid in the same way as when mak­ing an Imagescan. Mark the edge(s) for the transition
to the next grid using a PUA 70 marker, as shown below.

Switch on the scanner. Move to the Blockscan symbol.
The battery level is given, together with the number of
Imagescans currently held in the memory out of a max­imum of 9.

To begin, select Blockscan from the main menu.

A representation of a Blockscan is shown on the screen.
Each square represents an Imagescan. Up to 3 ×3 Image­scans can be scanned. Select the position of the first
Imagescan that you will make in the series using the
Arrow buttons. Press Confirm to begin the first Image-
scan. Note that the coordinates of any points on the
Blockscan will be referenced from the upper left corner.

Refer to the previous section for details on how to car­ry out the Imagescan. When the Imagescan is complete,
the system returns to the Blockscan screen.

grid overlap and the scan areas are aligned as shown in
the diagram.

Select the location of the next Imagescan and repeat
the scanning process. Completed Imagescans may be
repeated by simply reselecting the area to scan and per­forming the Imagescan process. The data will be over­written. When sufficient Imagescans have been made,
or when all nine are complete, press Cancel to return
to the main menu and transfer the data to the monitor.
Please refer to section 7.4.

-CAUTION-

Pressing the Cancel button twice causes the recorded
Imagescan to be deleted. The screen then returns to the
main menu.

7.2.8 Error messages from the scanner when
starting or scanning

Error messages may be displayed graphically on the
scanner. Generally, a stop symbol indicates a fatal error
with the scanner. In this case, the scanner requires to
be serviced at a Hilti repair center.

or

One of these symbols may be displayed immediately
after the scanner is switched on. They indicate a possi­ble electronic fault. Switch the scanner off and then back
on again. If the error message appears again, the appli­ance will need to be sent to Hilti for repair.

An exclamation symbol indicates either an error caused
by the operator or an error that can be solved by the
operator.

This symbol may appear either when trying to enter the
Imagescan or Blockscan scanning mode, when trying
to begin a new Imagescan within Blockscan scanning
mode or when trying to start Quickscan recording. It
indicates that the memory allocated for the operation is
full and that no more data can be stored. In this situa­tion, the data must either be transferred to the monitor
or deleted from scanner memory.

-WARNING-

Deleting the scanner memory may result in permanent
data loss. Data that has not been transferred to the mon­itor will be permanently deleted.

This symbol may appear during any type of scanning
when the Scanner is being moved over the surface. It
indicates that the Scanner is being moved too quickly
to allow it to process all the signals generated. The maxi­mum speed is 0.5m/s or 20 inches/s.

If the symbol appears during Quickscan detection, press
Confirm and repeat the scan. During Quickscan record­ing, press Confirm. You will need to begin the record­ing operation again from the original starting point or
from where the last marker was set. During Imagescan,
press Confirm and repeat the row or column previous-
ly scanned. In all cases, move the scanner more slow­ly over the surface.

This symbol may appear if the scanner has been moved
in the wrong direction during scanning, e.g. you begin
scanning from right to left but during the scan move the
scanner toward the right. The warning does not appear
immediately, but only when moved 15 cm or more in
the wrong direction.

7.3.5 Imagescans

Imagescans show a representation of the reinforcement
layout. The layout can be referenced on the surface, the
depth determined at any point and the diameter of a bar
estimated at any point.

Select Analyze… to analyze the image.

7.3.5.1 Analyzing the image

The bar depth and diameter may be determined at any
point on the image. Other analysis options include view­ing horizontal slices through the image at different depths
and a calibration option for an accurate check of depth
of cover.

View Range + and View Range – raise or lower the
depth at which the scan is viewed. This is useful when
trying to find which bars lie closest to the surface and
for an overall impression of how level the reinforcement
is compared to the concrete surface.

Full Scan Analysis

This function performs an analysis of the complete image.
All bars within the area of the image are calculated and
shown.

Cal. Depth/Ø – Used to calculate the depth and diame­ter of a bar at the point where the cursor lies.

-WARNING-

When scanning bars that are welded, it must be expect­ed that accuracy will not be within specifications. It is
not possible to determine from the image whether bars
are welded at their intersection points. If in doubt, remove
concrete from the structure at an intersection to deter­mine whether the reinforcement is welded.

7.3.5.1.1 Selecting the view range

Press View Range to reduce the image depth viewed.

The current depth range viewed is displayed in the infor­mation bar at the bottom of the screen (e.g. 0–85 mm).

Use View Range – and View Range + to adjust the depth
at which the image is viewed. In this way it is possible
to determine which bars lie closest to the surface and
how level the reinforcement is in relation to the surface.
In the example shown, the vertical bars lie closest to the
surface.

58

59

en

Note that the depth value given is an estimate and does
not conform to the specifications given in section 4.0.
To return to the original view, press View Range + until
the maximum view range is displayed.

7.3.5.1.2 Full scan analysis

A full scan analysis can be used to evaluate the com­plete scanned image.

-NOTE-

This operation may take some time.

When calculation is complete, all data from the analy­sis is shown on the screen. Calculate Depth/Ø can then
be used to determine the results at any point on a rein­forcing bar shown on the screen.
Full Scan Analysis is used mainly to show the position
of the bars and to determine locations where holes can
be drilled without risk of hitting bars.

7.3.5.1.3 Calculating depth and diameter

Use the Arrow buttons to move the cursor to the point
on the bar you are interested in. The position of the cur­sor is displayed in the information bar at the bottom of
the screen. Press Calculate Depth/Ø.

To display the depth and diameter at that point, press
Cal. Depth/Ø. The system then calculates the depth and
the diameter.

The position of the point calculated is displayed as a
small target with an arrow either side showing the direc­tion of the bar. The depth and diameter of the bar are
displayed in the information bar at the bottom of the
screen together with the coordinates of the point cal­culated.

If no depth or diameter values are given, then these lie
outside what could be reasonably expected. When cal­culating depth and diameter, several points must be
observed:

-WARNING-

Diameter calculations are based on one of the following
standards for steel reinforcement:

Standard

DIN 488
ASTM A 615/A 615M-01b
CAN/CSA-G30, 18-M92
JIS G 3112
GB 50010-2002

Origin/applicability of the standard

European Union
United States of America
Canada
Japan
China

60

en

Diameters given for bars that do not conform to one of
these standards may not fall within the accuracy spec­ifications.

-WARNING-

The diameter calculation is an estimate and intended to
indicate probable diameter only. If the bar diameter must
be known with 100 % certainty, concrete must be removed
from the structure and the bar measured physically.

-WARNING-

Never attempt to determine the diameter of a bar by mea­suring it on the image. Whilst the center of the bars in the
image correspond with those in the structure, the image
is not a scale drawing of the bars. The width of the bars
shown is representative of the signal strength received
by the scanner. Small bars close to the surface may thus
appear similar in size to larger bars at greater depth.

-NOTE-

The most accurate and reliable diameter and depth values
are obtained at points on the bar as far away from other
bars as possible and away from edges of the scan that are
parallel to the bar in question. Effects at the edges of the
scan may affect bars lying parallel typically up to 100 mm
from the edge.

Depth and diameter calculations should not be made along
the grid lines and not at points where bars cross.

Other factors influencing depth and diameter accuracy
are rough scanning surfaces, ferrous or magnetic sub­stances in the concrete mix, a smooth scanning technique
starting at the correct point on the grid and following
the grid lines exactly and an adequate ratio between cov­er and bar spacing.

Please refer also to section 7.5 for further advice on how
to get the most out of the system.

-NOTE-

If the bar diameter is known, it can be entered under Fix
Diameter. See below.

Fixing the diameter

If the diameter is known, the value should be entered as
this improves the accuracy and reliability of depth deter­mination. Press Fix Diameter.

Set the diameter to On using the left or right arrow but­tons. Move to the diameter input field using the up or
down arrow buttons and select the diameter.

Press Done to confirm the selection and return to the
scan. The Fix Diameter symbol appears in the status bar
to the right of the display.

Calibrating the image

This option is intended for measurements of the high­est accuracy and can be used when the depth and diam­eter of a bar at a certain point are already known. It should
be used with caution as improper use can lead to incor­rect depths being displayed. The image will be calibrat­ed depending on the information given and the depth
around the point calibrated will be given with the utmost
accuracy. It is normally only of use to manufacturers of
precast concrete components.

Depths and diameters of bars in a different part of the
scan may lie outside the specification if the calibration
function is applied.

After moving the cursor to the point where the depth
and diameter are known, select Calibrate.

Set Calibration to On and enter the depth and diameter
values for this point on the image. Press Done to con­firm and return to the scan. The system checks whether
the values entered are plausible based on the informa­tion it has for that point. If this is not the case, calibra­tion will be rejected.

61

en

The calibration symbol appears in the status bar to the
left of the display. If the information entered was accu­rate, the depth and diameter around the point will be
shown with increased accuracy.

-WARNING-

Calibrating the scan with incorrect values can lead to depth
readings outside the quoted accuracy specifications.

7.3.6 Blockscans

Blockscans consist of up to 3 ×3 Imagescans that have
been scanned at positions adjacent to one another and
then automatically stitched together.

Blockscan with all blocks scanned:

Blockscan with some of the blocks scanned:

7.3.6.1 Analyzing a Blockscan

Select Analyze.

View Range + and View Range – raises and lowers the

depth at which the scan is viewed, as with Imagescan.
This is useful when trying to find which bars lie closest
to the surface and for an overall impression of how lev­el the reinforcement is compared to the concrete sur­face.
Use the arrow buttons to select the block you wish to
analyze. Select Scan displays the Imagescan marked for
analysis. Refer to section 7.3.5 for details of how to ana­lyze individual Imagescans.

7.3.7 Quickscans

Quickscans recorded in the scanner can be analyzed to
provide information about the number and average depth
of reinforcing bars over a large area of the structure.

The Quickscan is displayed as a graph containing a series
of vertical bars or peaks. The horizontal axis represents
the distance traveled along the structure. The vertical
axis represents the signal strength or, after analysis, the
depth of cover. Each peak represents a reinforcing bar.

Select Analyze… to analyze the Quickscan.

-NOTE-

To carry out an accurate analysis, the diameter of the
bars must be known and entered. If the bar diameter
has been set in the scanner, this diameter will be trans­ferred automatically to the monitor. If the diameter has

62

en

not been set, a diameter value will be assigned auto­matically (please refer to 7.2.5.4). If the real bar diam­eter is different, it must be set under Fix Diameter when
calculating the depth.

7.3.7.1 Analyzing Quickscans

Select Analyze

In the information bar at the bottom of the screen, the
following information is displayed:

– The length of the Quickscan
– The currently set diameter of the bars
– The depth at which the trigger is currently set
– The number of bars at or above the current trig-

ger depth

! – Estimate of the number of bars (before analysis)

– The average depth of the bars in the Quickscan

(displayed after calculation has been made).

– The standard deviation of the calculation, indi-

cating the amount of deviation in the depth of
the bars.

Zoom +/Zoom – can be used to increase/decrease the
zoom level for viewing the Quickscan signal. The bar at
the top of the screen gives an indication of the zoom lev­el selected and the currently viewed position in the scan.
The length of the current view is indicated by the figures
shown in the bottom right and bottom left corners of
the image. Move along the scan using the arrow but­tons when zooming. Various zoom levels can be used.
Zoom is at maximum when Zoom + is grayed and no
longer active.

Cal. Depth – opens the calculation menu.
Hide Grid – removes the scale shown at the side of the

graph.

Calculating the depth

Press Calculate Depth…

Ensure that the diameter is set to the correct value. Use
Fix Diameter and select the appropriate value.

The trigger depth is used to set a depth of particular
interest. This is usually the minimum cover required
over the first layer of reinforcement. Use the arrow up
and down buttons to adjust the trigger depth.

Press Cal. Depth to calculate the average cover depth
and standard deviation of all the bars in the Quickscan.
The evaluation is performed.

After several seconds, the results are presented in the
Information Bar at the bottom of the screen.

7.4 Data transfer between the scanner and monitor

Data is transferred from the scanner to the monitor using
the infrared connection. The infrared ports are located
on the ends of the scanner and monitor as shown below.

Infrared port on the scanner

Infrared port on the monitor

-NOTE-

The maximum range of the infrared connection is approx­imately 30 cm (12 inches). The maximum angle between
scanner and monitor for successful data transmission
at close ranges (up to 10 cm or 4 inches) is ±50° rela­tive to the axis of the infrared port on the monitor. At a
distance of 15 cm (6 inches), this angle is reduced to
±30°. At a distance of 30 cm (12 inches), the scanner
must be accurately aligned with the monitor to ensure
successful data transmission.

-CAUTION-

Ensure that the windows covering the infrared ports are
free from dirt, dust and grease and are not excessively
scratched before commencing data transfer. Failure to
do so may result in a reduced transfer range or may pre­vent the data being transferred.

-WARNING-

Never remove the memory card while data transfer is in
progress. Data may be permanently lost.

7.4.1 Procedure for data transfer

Data can be transferred whenever the monitor and scan­ner are switched on and the scanner is in the main menu.
Data is transferred to the currently selected project on
the monitor.

-NOTE-

Ensure that the correct project is selected on the mon­itor before transferring data.

Bring the scanner and monitor close together so that
the infrared windows are facing each other. The scan­ner and monitor automatically sense each other and
establish communication. The following screen appears
on the scanner and a beep sounds:

Press Confirm on the scanner to begin data transfer. The
following screen is shown while data transfer is in
progress:

The infrared symbol is displayed on the monitor screen:

this indicates that data transfer is in progress. The

red LED on the scanner flashes constantly.

Data transfer takes between 1 and 15 seconds, depend­ing on the number and length of scans contained in the
scanner. When data transfer is complete, the following
screen appears:

The infrared symbol on the monitor reverts to until
the data has been secured on the memory card or inter­nal memory.

Then the infrared symbol then reverts to "ready":
All scan data has then been successfully transferred.
Press the Confirm button to delete the scans in the scan­ner and return to the main menu.

7.4.2 Error messages during data transfer

This symbol may appear on the scanner during data
transfer between the scanner and monitor. It indicates
that the data transfer has been interrupted or commu­nication cannot be established. Before retrying to trans­fer data, ensure that the scanner and monitor are with­in the maximum range of 0.3 m (12 inches) and that
they are accurately aligned with each other. Ensure that

the atmosphere is dust-free as far as possible and that
the infrared windows on both scanner and monitor are
clean and relatively free from scratches. Excessively
scratched windows must be replaced by Hilti Service.

During data transfer, try to hold the monitor and scan­ner correctly aligned for the entire period that data is
being transmitted.

This symbol may appear while transferring data from
the scanner to the monitor. Remedy the problem by
switching the units off and on again and check their align­ment with each other. If the error message reappears,
the appliance will need to be sent to Hilti for repair.

In the event that data transfer is interrupted, data can­not be lost. Data is deleted from the scanner only once
all scans have been successfully transferred and the
Confirm button on the scanner has been pressed.

7.5 Tips for scanning and evaluation

Object too narrow to scan or reinforcement is too close
to an exterior corner to be scanned properly.

Use a thin overlay board that extends beyond the edge(s)
of the structure and scan on the board beyond the edge.
Note that the thickness of the board must be deducted
from any depth measurements. The thickness of the
board can be entered in the PC application. This value
will then be automatically deducted from any depth mea­surements.

Surface is rough.

Rough surfaces (e.g. concrete surfaces with exposed
aggregates) cause additional noise in the signal and may
mean that the depth or diameter of a bar cannot be deter­mined. In such cases it is also advantageous to scan on
a thin overlay board. The same reminder about deduct­ing the thickness of the board applies, as above.

"Interference" in images

Interference in images may occur due to:

– Scraps of reinforcement in the concrete
– Tie wires where rebars cross
– Aggregates with ferromagnetic properties
– Ends of bars lying parallel to the scanning plane
– Ends of bars lying orthogonal to the scanning plane

(bars scanned end-on.)

-NOTE-

Diameters and depths calculated in the area where inter­ference occurs must be treated with caution as they may
be inaccurate.

Scanning columns and beams for penetrations

In such cases where the reinforcement must not be
damaged, ensure that Imagescans are made on at least
three sides of the component in order to ensure that
shear bars (placed at an angle in the concrete) can also
be identified.

Simple diameter check

A simple, rough check of the diameter of the bars in the
first layer can be made by deducting the depth of the
second perpendicular layer from that of the first. This
assumes however that the two layers touch each other
or are at least very close.

7.6 PC software

The PC application provides functions for enhanced
analysis, easy creation of reports, data archival, image
and data export to other PC applications as well as auto­mated batch processing of large volumes of data.

Instructions for installation of the software can be found
on the PSA 90 PC-SW CD-ROM. Detailed information
about using the PC application can be found in the Help
menu.
