transferred to a PC.

4 Product Description © 2007 Proceq SA
2.3 Universal Probe
2.3.1 Functioning
The universal probe is designed to function in relation to
the direction. This means it reacts most sensitively to the
rebars parallel to its longitudinal axis, and least sensitive-
ly to the ones at right angles to its longitudinal axis.
For this reason the probe should be positioned parallel to
the bars to be tested and moved over them sideways for
scanning.
The probe has both a small and a large measuring
range. Use the ←and →keys to switch over between
the two measuring ranges. The active measuring range
is displayed in the measuring display (see Fig. 5.1).
The large measuring range should only be used if the
concrete cover is larger than is shown in the intersection
point of the curves in Fig. 2.4. If the bar diameter is 16
mm, this applies for a cover of approx. 60 mm.
2.3.2 Measuring Ranges and Accuracy
Fig. 2.3 Measuring ranges and accuracy of the universal
probe
Key:
Ø: Bar diameter in mm
#: Bar diameter in «Bar size #»
---: Lowest accuracy limit required by the standard
BS 1881: Part 204: ±2 mm or ±5 %
PROFOMETER 5+measures up to 50 % more accurate-
ly than required by this standard.
The size of the two measuring ranges of the universal
probe depends on the bar diameters. The accuracy of
the concrete cover indication refers to individual bars.
See also Fig. 2.4.

English

2.3.3 Resolution
Fig. 2.4 Resolution
On concrete elements, measurements are often influen-
ced by neighboring bars. For parallel bars in the same
layer, the diagram in Fig. 2.4 shows the smallest bar
spacings a at which rebars are still identifiable individu-
ally in relation to concrete cover s. For intersection points
of the bar spacing a and concrete cover s above the cor-
responding curve the current value indicates the approxi-
mate depth of the reinforcement level. For possibility for
correction, see «Corrections», page 7.
Example of bars in a position which can still be located:
Bar diameter d = 16 mm, concrete cover s = 55 mm and
smallest bar spacing a = 70 mm.
2.4 ScanCar
Fig. 2.5 ScanCar with integrated universal probe
For the SCANLOG model, the ScanCar is required to
perform the «CyberScan» and «Measure with Grid»
functions. For model S, it can be used as a carriage
without any other functions.
If the path measuring cable is connected, the
air gap of 4 mm between the probe and the
concrete surface is automatically corrected
when the concrete cover is displayed.

4.1 Bar Diameter
Setting the bar size that exists on the structure makes a
good basic accuracy of the cover readings possible. The
suggested default size is 16mm or #5. The bar diameter
setting can be done in metric units and US bar size
numbers.
Metric System
The bar size can be increased in mm. This makes it
possible to set bar diameters according to different

English
© 2007 Proceq SA Settings 7
standards. The instrument indicates concrete cover
depth and distances in [mm] and [m] respectively.
US System of Units
In this system the bar sizes must be set in numbers 01
to 16. The «bar size #» specifies the diameter in eights
of an inch. In this mode the instrument indicates cover
depth and distances in inches and feet.
Example: Bar size #5 corresponds to a diameter of 5/8”
(15.9mm).
• To switch from mm to inches press the MENU key and
subsequently select «Basic Setups» and «Unit»
4.2 Object Number
The measured values can be stored under object numbers.
The following number is set automatically as the first
digit of the six-figure object number according to the
measuring function:
- 1 for «Measure w. Statistics»
- 2 for «Scanning Bars»
- 3 for «Measure with Grid»
4.3 Limit Value
For description, please see under «Measure with
Statistics», page 9 and «Detecting Insufficient Concrete
Cover», page 12.
4.4 Corrections
Neighboring bar corrections
This mode is mainly used for determination of the bar
diameter in close spaced parallel bar arrangements.
There are structures where the bar spacing is smaller
than indicated in Tab. 5.2. When measuring these bars,
the displayed value of the concrete cover is too low and
the diameter value too high. In such instances, correc-
tions can be made. This however only applies to the
parallel bars on both sides. The bars that are arranged
crosswise must have the minimum spacing shown in
Tab. 5.2.
• Enter the previously determined bar spacing. See
«Measure with Statistics», page 9, «Detecting Insufficient
Concrete Cover», page 12, «B. Determining diameters
with correction», page 14, «Making Reinforcement
Visible with CyberScan», page 14 and «Measure with
Grid», page 17.
2-Layer-Correction
This mode is used for cover measurement in congested
standard orthogonal bar arrangements. A more accurate
cover reading can be reached by use of this correction.
The congested bars induce a too strong measuring
signal which can be corrected this way.
• Select the spacings a and b which you determined by
locating the bars. In some cases the bar diameters
cannot be measured by the PROFOMETER 5+ and
must be determined by removing the concrete. The
diameter setting is automatically selected as 16mm.

4.5 Language
The language of the display texts can be selected.
4.6 Basic Setups
The following settings are possible:
- Unit
If you choose «mm» the bar diameter setting can be
selected in mm and the results will be indicated in the
metric system. If you chose «inch» the bar diameter
setting can be made in bar size numbers and the
results are indicated in imperial units. Please refer also
to «Bar Diameter» on page 6.
Warning!
By changing the unit from mm to inch or vice
versa existing measured and stored values are
falsified. In order to avoid confusing results the
user must clear the memory after changing the
units.
The mode «2-Layer-Correction» can only be used for
metric units.
- Probe
When starting up the device for the first time,
the code no. engraved on the probe must be

5.1 Measure with Statistics
This function can be used to locate rebars, measure
concrete covers and determine bar diameters. The cover
values can be stored under object numbers.
5.1.1 Rebars Connected with Binding Wires
Settings
See also under «Settings», page 6.
• Enter the bar diameter.
If the bar diameter is unknown,
enter 16 mm.
• Enter the object number.
Limit value: To avoid confusions, set the limit value
to «0» during the measuring process. Enter the value
required for the building after completion of the series of
measurement. The percentage of the covers that are too
small will be displayed in the statistical evaluation. See
also «Detecting Insufficient Concrete Cover», page 12.
• Enter the desired audible locating aid («MENU» →
«Basic setups» →«Audible locating aid»): (Short) beep
tone or variotone.
• Enter the requested values under the menu option
«Corrections» → «Neighbouring Bar Correction» or «2-
Layer-Correction» if the correction is required.
• Select the «Measure w. Statistics» function.
• Press the START/RESET key.

If required the backlight of the LCD can be switched on.
This can be done by pressing key ↑ for more than 2s.
RESET process
• Hold the probe in the air and press the START/RESET
key. A bar appears in the display that informs you on the
progress of the procedure. The probe shall not be moved
before the bar has disappeared and «0» is displayed.
• Please repeat this check procedure from time to time.
Locating the rebars and measuring the concrete cover
For locating the rebars, the diameter setting is not as
important as for measuring the cover.
In the case of double layer arrangements of
rebars, always start the location with the first
layer.
If the rebars of the first layer are too close to
each other, it is likely to be impossible to lo-
cate the bars of the second layer. See also
«Universal Probe», page 4.
• Move the probe from a starting position in one direc-
tion. Observe the locating aids: current concrete cover,
flow bar, (short) beep, variotone, signal value. As long
as the flow bar moves to the right, the probe is approa-
ching a rebar. If the flow bar stops moving, the probe is
directly over the rebar axis. If the centerline of the
probe has overshot the rebar axis somewhat, acoustic
and visual indication is given in the «beep» setting by a
short beep and by «—» in the «Current cover» display
field. At the same time, the flow bar moves to the left
and the cover is temporarily stored in the field Memo».
• When having activated the audible locating aid «Vario-
tone» («MENU» →«Basic Setups» →«Audible locating
aid»), the audio frequency increases as the probe
approaches a rebar. In this operation mode the cover
of the scanned rebar is also temporarily stored in the
field «Memo».
• In the case of loud noises from the surroundings, use
the headset to hear the acoustic signals.

English
© 2007 Proceq SA Measuring Process 11
Irrespective of the settings, the signal value is
a yardstick for the distance between the probe
and a metallic object.
• The bar direction can be detected by moving the probe
in the direction of its longitudinal axis along the rebar.
Make sure that the signal value and the current cover
remain as constant as possible.
Storing the measured values
To store the measured values, select an object number
in the menu.
• Press the PRINT/STORE key to store the measured
value shown in the field «Memo».
• Use the ↓key to delete the measured value, or in the
case of several values, the last of the remaining mea-
sured values.
Warning!
You cannot undo the deletion of a value!
• To receive a statistical evaluation of the stored measu-
red values, press the END key.
• If you then enter a limit value («MENU» →«Limit Value»),
the percentage of the measured values which are
below the entered limit value is displayed.
• Pressing END again completes the measurement
series and starts a new one with an object number that
is incremented by 1.
Measuring the diameter
See «Rebars Connected with Binding Wires», page 13.
5.1.2 Welded Reinforcing Meshes
The unit cannot detect whether the rebars are welded to
one another or connected with binding wires. The two
reinforcement types with the same dimensions however
create different signals.
Settings
• Proceed as described under «Rebars Connected with
Binding Wires», page 13.
• Observe the following exception:
The setting of the bar diameter must be slightly higher
than the actual diameter (see Tab. 5.1, page 12). The
input depends on the bar diameter and on the mesh
width. With special constructions, this value should be
determined by means of a test on an open system.
Use different distance pieces to find out the diameter
setting at which the correct cover is indicated.
Examples for diameter settings:
Fig. 5.2 Welded reinforcing mesh

12 Measuring Process © 2007 Proceq SA
Tab. 5.1
• Select the small measuring range in the measuring
display. The large measuring range cannot be used
with welded reinforcing meshes.
Locating and measuring concrete covers
Here, the spacings between the bars of the other layers
of the mesh can also be located more easily. This par-
ticularly applies to the bars of the second layer.
The value displayed for the cover of a bar of the first
layer can vary by a few millimeters depending on wheth-
er the measurement is made over the point at which two
bars cross, or between the bars of the second layer.
If the rebars of the first layer are too close to
each other, it is likely to be impossible to loca-
te the bars of the second layer. See also
«Universal Probe», page 4.
Storing the measured values
• Proceed as described under «Storing the measured
values», page 11.
Measuring the diameter
«Welded Reinforcing Meshes», page 14.
5.2 Detecting Insufficient Concrete Cover
This function can be used for the following tasks:
- Check after removing formwork
- Building inspection
- Evaluation basis for modernisation
Settings
See also under «Settings», page 6
• Enter the bar diameter.
• Enter the limit value of the cover.
• Enter the bar spacing under the menu option «Neighb.
Bar Corr.» if the correction is required. The set limit va-
lue is not displayed in this case (see Fig. 5.1).
The setting of the audible locating aid is not of impor-
tance.
Measuring the concrete cover
With a preselected limit value, the probe can be moved
at a maximum search speed of 0.25 m/s without having
to watch the display. If the current cover displayed is less
than the limit value, an acoustic alarm sounds. When the
probe is over the bar, «—» is indicated in the «Current
concrete cover» display field.
Switching off the unit deletes the set limit
value.

5.3 Determining the Bar Diameter
5.3.1 Rebars Connected with Binding Wires
A. Determining diameters without correction
For precise determination of the bar diameter, it is impor-
tant that there are no unnoticed influences that could fal-
sify the result. Therefore select a place on the structure
where there is sufficient spacing between the rebars.
If the spacings are too small, the resulting value will be
too high.
To measure the bar diameter in the first and second
layer, the minimum spacings a and b as shown in Tab.
5.2, page 13 are required.
• Select the «Measure w. Statistics» function.
• Carry out the RESET procedure. See also under
«RESET process», page 10.
• Place the probe parallel over the bar and press the ↑key.
• The result of the bar diameter determination is
displayed in mm or inch.

The result of diameter determination cannot be
stored.
B. Determining diameters with correction
There are structures where the rebar spacing is smaller
than indicated in Tab. 5.2. Corrections are possible for
these structures. However, this only applies to the paral-
lel bars on both sides. The bars that run crosswise must
have the minimum spacings shown in Tab. 5.2.
Procedure:
• Locate the parallel rebars carefully and mark them on
the surface of the concrete.
• Measure the rebar spacings using a measuring rod
and enter the data in the «Corrections» →«Neighb.
Bar Corr.»
• Select the «Measure w. Statistics» function.
• Hold the probe in the air and carry out the «RESET
process» as described on page 10.
• Place the probe parallel over a bar and press the ↑key.
As bar diameter (d=...), the display shows the value cor-
rected by the influence of the neighboring bars.
• In addition to the bar spacing, the measured bar dia-
meter can now be entered in the menu.
With these settings, the concrete cover of those rebars
found to be situated close to one another can be deter-
mined precisely.
Only concrete covers can be stored under the
selected object number, not the measured bar
diameter!
5.3.2 Welded Reinforcing Meshes
If diameters are determined on welded rebar systems,
results are displayed most of the time. These values are,
however, always too high and cannot be used.
5.4 Making Reinforcement Visible with
CyberScan
Model SCANLOG only (with mobile probe)
The rebars arranged below a defined measuring area
are displayed. Using the x/y scales, rebars which have
to be exposed, or points where holes have to be drilled,
can be transferred immediately from the display to the
measuring area and marked.
The measuring area must be scanned with the mobile
probe once in direction x and once in direction y (see
«ScanCar», page 5). The rebars are located and dis-
played extended to the full size of the measuring area.
Measuring areas of 0.5 x 0.5 m, 1 x 1 m or 2 x 2 m can
be selected.
If the area that must be measured is smaller than the
size of the selected area the bars are only shown in the
length they were measured.
