- The location and orientation of the rebars

- The position between two rebars

- Cover depths 15mm / 0.59” and 60 mm / 2.36”

- Diameter 16 mm / #5

Congratulations! Your new Profoscope is fully operational
and you can now continue with your measurements.

Performing a Reset

The pulse induction measuring principle is liable to drift
with temperature and other external influences. Performing
a reset corrects for any drift and ensures accurate meas­urements. We recommend a reset every 5 minutes or so.

On power on, the Profoscope re­minds the user to perform a reset.

Hold the Profoscope in free space (no metal within a
40cm / 16” sphere) and press the reset key. The dis­play rotates for approximately 2.5s while the reset is car­ried out.

2 Tutorial

2.1 The Measurement Principle

The Profoscope uses electromagnetic pulse induction
technology to detect rebars.
Coils in the probe are periodically charged by current
pulses and thus generate a magnetic field.
On the surface of any electrically conductive material
which is in the magnetic field eddy currents are produced.
They induce a magnetic field in opposite direction. The
resulting change in voltage can be utilized for the meas­urement.

Coils

Concrete Magnetic Field

Rebar

The Profoscope uses different coil arrangements to gene­rate several magnetic fields. Advanced signal processing
allows

1. Localization of a rebar

2. Localization of the mid-point between rebars

3. Determination of the cover

4. Estimation of the bar diameter

This method is unaffected by all non conductive materials
such as concrete*, wood, plastics, bricks etc. However
any kind of conductive materials within the magnetic field
(approx. 400 mm / 16” sphere) will have an influence on
the measurement.

i

Note: Remove all metallic objects such as rings
and watches before you start measuring.

* Some concrete types and other structural materials may
have metallic content.

2.2 The Measuring Range

The pulse induction principle used by Profoscope has a
defined range of operation.
The measuring range is dependent on the bar size. The
expected accuracy of the cover measurement is indicated
in the graphic below. (Complies with BS1881 part 204, for
a single rebar with sufficient spacing).

2.3 Factors Affecting the Measurement

2.3.1 Errors due to Neighboring Bars

All rebars within the sphere of influence affect the reading.

Sphere of influence
400 mm /16 inch

MC

Neighboring bars close to the target bar result in an under­estimated cover value and an overestimated bar dia­meter.

i

Note: This effect can be reduced by the neigh­boring bar correction implemented in the Profo­scope.

2.3.2 Resolution

There is a limit on the minimum spacing of bars depend­ing on the cover depth. It is impossible to distinguish be­tween individual bars below these limits.

2.3.3 Effect of Setting Incorrect Bar Diameter

The accuracy of the cover measurement is also depend­ent on setting the correct bar diameter.
The following two charts give an estimation of the error in
percentage of the cover reading for different rebar sizes if
a default size of 16mm (#5) is set.

2.3.4 Factors Affecting Diameter Determination

Two factors affect the determination of the rebar diameter.
One is the cover depth. Diameter can be determined for
rebars with cover not exceeding 80% of the small range.
(64 mm, 2.5”)

The second is the separation between neighboring bars.
The separation between the bars must be greater than the
limits shown in the drawing below (with reference to the
MC) for accurate determination of diameter.

2.3.5 Orientation

The strongest signal results when the center line of the
probe is parallel to a bar. The center line in the Profoscope
is the long axis of the instrument. This property is used to
help determine the orientation of the rebars.

3.2 Locate a Rebar

☺ Switch on the Profoscope and perform a reset as ex-

plained in “Getting Started”. The Profoscope can im­mediately be used to locate a rebar.

i

Note: The Profoscope is able to locate a rebar
and also the mid-point between two rebars. It is
important to be able to recognize which is which.

3.2.1 Finding a Rebar

Step 1 – Place the Profoscope on the test surface and
move it slowly in a chosen direction. The Profoscope re­acts differently depending on its orientation relative to the
rebars. There are three scenarios.

Scenario A)
Sweeping Parallel to the Rebars

☺ Try it out on the start-

up test kit.

Real Tests

14 © 2008 by Proceq SA

Arrows indicate proximity of rebars off screen.

Continue sweeping in the chosen direction.
As you get closer, the rifle scope indicates either:

The presence of a rebar beneath the instrument or,•
The mid-point between two rebars beneath the instru-•
ment.

It is very simple to differentiate between the two.

Approaching a Rebar

Rifle scope moves in opposite direction to the Profo­scope.
The signal strength is increasing  as the rifle scope
moves towards the center line.

Approaching a Mid-point

Real Tests

© 2008 by Proceq SA 15

Rifle scope moves in the same direction as the Profo­scope.
The signal strength is decreasing  as the rifle scope
moves towards the center line.

i

Confirm that you are approaching a rebar.

Continue sweeping until the rifle scope is in the center of
the screen. When it is centered exactly, the LED indicator
will light. (If the acoustic signal is activated it will sound
as long as the LED is lit). The rebar is directly beneath the
measurement center.

Rebar centered

Scenario B)
Sweeping Perpendicular to the Rebars



☺ Try it out on the start-

up test kit.

If there are rebars within range, the rifle scope will remain
close to the center of the screen and move very little.

Little or no movement of
the rifle scope.

In this case turn the Profoscope by 90° and continue
sweeping as described in the previous section.

Real Tests

16 © 2008 by Proceq SA

Scenario C)
Sweeping at an Angle to the Rebars

☺ Try it out on the start-

up test kit.

The response on the screen will be similar to the case
when you are sweeping parallel, but the movement of the
rifle scope will be slower.

3.2.2 Check the Orientation

Step 2 – Once you have located the rebar, you need to
check the orientation of the bar by rotating around the
measurement center.

☺ Try it out on the start-

up test kit.

i

Note: Ensure that the rifle scope remains cen­tered as you rotate.

Rotate until you get the minimum cover value and the LED
indicator is lit.

i

Note: The signal strength arrow  can also be
used as an aid here. The signal strength will in­crease as you rotate towards the correct orienta­tion and decrease as rotate away.

Real Tests

© 2008 by Proceq SA 17

The center line of the Profoscope is now directly above
the rebar and pointing in the same direction. Mark at either
end of the instrument with chalk or similar.

3.2.3 Verification

Step 3 – Verify by moving the Profoscope in the direction
of the rebar and observe that the cover depth reading dis­plays a constant value.

3.2.4 Locate a Mid Point

Step 4 – Continue sweeping with the center line of the
Profoscope parallel to the rebar you have just located. As
you approach the mid-point between two rebars the rifle
scope will appear on the screen again. This time:

• Theriescopewillmoveinthesamedirectionasthe

Profoscope.

• The signal strength will be decreasing  as the rifle
scope moves towards the center line.

Center the rifle scope as described previously to locate
the exact position of the mid point.

☺ You may want to mark the mid-points as well as a

guide to drilling holes.

3.2.5 Map out the Rebar Grid

Step 5 – “Reset” the Profoscope again and then start
the process once more to locate further rebars.

Sweep in one direction first and then at 90° to build up
the grid.
You will soon have a good representation the rebar con­figuration to help you begin drilling or to conduct further
measurements of cover depth and rebar diameter and so
forth.

3.2.6 Advanced Settings (Measuring Range)

short, long, auto, auto

This symbol in the top left corner of the screen indicates
the measuring range set. Toggle between ranges with the
short cut describe in chapter 3.1.

The range can also be set in the main menu by
selecting the following icon.

Choose the short range to accurately detect rebars that
are embedded closer to the concrete surface.

The long range setting will allow rebars embedded deeper
in the concrete structure to be detected. However, it will
create a larger sphere of influence which in turn means
that neighboring rebars may affect the reading.

Alternatively, choose the automatic setting that will au­tomatically toggle between the short range and the long
range.

3.3 Measure Cover Depth

Once the rebar grid has been located the cover can be
measured.

3.3.1 Set the Rebar Diameter

☺ An accurate knowledge of the rebar diameter will also

give best cover depth results.

The default reference rebar diameter set in the instrument
is 16 mm or #5. This can be seen in the status row at the
top of the display screen.

Step 1 - If you already know the actual rebar dia­meter, select the icon in the menu to set this as
the reference.

i

Note: If you DO NOT know the rebar diameter,
then proceed to chapter 3.4.

Real Tests

© 2008 by Proceq SA 19

3.3.2 Read the Cover Depth

Step 2 - Place the centre line of the Profoscope directly
over the rebar and read off the cover depth.

e.g.
Cover depth = 15 mm

i

Note: Ensure that the measurement centre is not
placed over a horizontal/vertical intersection in
the rebar grid.

3.3.3 Advanced Settings

(Neighboring Rebar Correction)

As described in the tutorial neighboring rebars
that are within the sphere of influence will also be

detected by the Profoscope and will affect cover
depth results. The effects of neighboring rebars can be
mitigated by keying-in a correction value.

i

Note: This works for rebars of the same layer run­ning in parallel to the rebar under test.

Measure the distance from the rebar under test to a
neighboring rebar. (See 3.2.5)

Enter the settings menu, select the icon and input this
value. Verify that neighboring rebar correction symbol
is active in the status line at the top of the display. Repeat
step 2.

3.3.4 Advanced Settings
(Minimum Cover Alert)

This is particularly useful for detecting insuffi-

cient concrete cover depth when conducting

large scale checks on structures after removing
the formwork or large scale building inspections and so
forth.

Real Tests

20 © 2008 by Proceq SA

Enter the settings menu, select the icon and set the re­quired cover depth limit. Verify that minimum cover alert
symbol is active in the status line at the top of the
display.
Move the Profoscope over the test surface. Whenever the
cover depth is less than the programmed minimum the
LED indicator will light and if it is enabled, an acoustic
alarm will be given.

i

Note: In this mode the LED will not light to indi­cate that a rebar has been located.

3.4 Measure Rebar Diameter

3.4.1 Determining Unknown Rebar Diameter

☺ The Chapter “Getting Started” shows that under the

right conditions the Profoscope can accurately deter­mine the diameter of a rebar.

The Tutorial chapter on the pulse induction principle de­scribes the limitations of the technology and clearly out­lines the conditions whereby accurate readings of rebar
diameter CANNOT be made if there is too much inter­ference from neighboring rebars or other metallic objects
within the sphere of influence.

We present 3 working methods which are recommended
to obtain the best results.

3.4.2 Create a Rebar Grid

Method 1  To map out a rebar grid on a test surface and
then to select one rebar from the grid that has sufficient
spacing from other rebars.

Step 1 - Create a rebar grid as described in chapter

3.2.5.

Step 2 - Select one rebar that has the largest spacing
from neighboring rebars.

Step 3 - Use a ruler and confirm that the spacing is at
least 150 mm (6”). If not, redo Steps 1 and 2 until a rebar

Real Tests

© 2008 by Proceq SA 21

is located with at least 150 mm (6”) spacing to a neigh­boring rebar.

Step 4 - Place the centre line of the Profoscope over the
rebar and click the function key on the left side.

The measured rebar
diameter replaces the
signal strength arrow.

Note down the rebar diameter.

☺ Try it out on the start-up test kit.

3.4.3 Work with a Default Value

Method 2  The purpose of this approach is to work with
a default value with known error tolerances.

From the menu item “Bar diameter” select the default
value 16mm or #5 for the diameter.

Use the chart in section 2.5 of the tutorial to understand
the errors that can be expected in the cover readings if the
actual rebar diameters differ from the reference value.

3.4.4 Drill Inspection Hole

Method 3  The purpose of this approach is to accurately
determine the rebar diameter through destructive means.

If neither of the methods 1 and 2 are feasible for what­ever reason and you are still in doubt (this could be the
case when rebars are bunched too close together or are
too small in diameter), then drill an inspection hole wide
enough to allow the use of a caliper to measure the re­bar diameter. Program this value into the Profoscope and
proceed.
