2 Product Description

2.1 Model S (Basic Unit)

The PROFOMETER 5+ rebar locator is a lightweight, compact device for the non-destructive location of rebars and for the measurement of concrete cover and bar diameters. The measuring method is based on the eddy-current principle with pulse-induction.

Indicating device

Universal probe

Fig. 2.1 Model S

The basic unit can perform the following functions:

- Locating rebars

- Measuring concrete covers

- Storing individual cover values and statistical evaluation

- Determining the bar diameters

2.2 Model SCANLOG

Indicating device

ScanCar

Universal probe

Fig. 2.2 Model SCANLOG

The SCANLOG rebar locator is identical to model S and comprises the following additional functions:

- «CyberScan» function for displaying the concrete cover

- «Measure with Grid» function for grey-scale display of the concrete cover

- ScanCar probe carriage with integral path measuring device for scanning the rebars

- Storage areas for «CyberScan» and «Measure with Grid» objects

In the case of both models, the data can be printed directly on a printer connected to the indicating device or transferred to a PC.

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 sensitively 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 accurately 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 influenced 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 individually in relation to concrete cover s. For intersection points of the bar spacing a and concrete cover s above the corresponding curve the current value indicates the approximate 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.

3 Startup

3.1 Connecting the Components

• Connect the universal probe to input A.

• If you want to use the ScanCar probe carriage, connect it to input B.

• If you use a headset, connect it to the socket marked with the headset symbol.

3.2 Putting the Indicating device into Operation

• Press the ON/OFF key. The following data is briefly displayed:

- Instrument model (model S or SCANLOG)

- Instrument serial no.

- Installed software version

- Whether automatic self-test is O.K.

- The more or less black battery symbol indicates the battery status

Then the measuring display of the previously measured object appears (Fig. 5.1, Fig. 5. 7 and Fig. 5.13) When the measuring display is visible the backlight of

the LCD can be turned on and off by pressing the ↑ key

for more than 2s.

If no display appears, replace the batteries.

4 Settings

The indicating device has a user menu navigation. Please follow the instructions in the display fields.

• Press the MENU key to display the main menu:

Modell SCANLOG only

Select menu option Call selected option Call measuring display of

the selected function

Fig. 4.1 Main menu

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

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, corrections 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.

This mode can only be activated in measuring function «Measurement with Statistics».

2-Layer-Correction

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

entered in the submenu «Probe».

- Audible locating aid

(Short) beep tone selectable in two frequencies or Variotone can be selected. The remaining settings are described under the respective functions.

5 Measuring Process

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 «Settings», page 6.

• Enter the bar diameter of the first layer.

• Enter the object number.

• Enter the bar spacing under the menu option «Corrections»

→ «Neighb. Bar Corr.» if the correction is required.

The «2-Layer Correction» can not be used by this function.

• Select the size of the grid field («MENU» → «Basic setups» → «xy-grid»).

The grid should usually be greater than the division of the first layer (e.g. +50 %) to ensure that at least one rebar is within a grid field.

• Set the range in which the concrete covers are to be displayed in grey scale («MENU» → «Basic setups» → «Display»). Change the grey scale range to improve the contrast of the displayed object (see Fig. 5.12).

Fig. 5.12 Adjusting grey scale range

The range can be adjusted as desired even after measuring.

• Select the «Measure with Grid» function.

• Pressing the START key calls the measuring display:

Fig. 5.16 Measuring area after measuring

• If the rebars of the first layer run in a vertical direction as shown in Fig. 5.14, the travel paths must be positioned horizontally with the selected grid spa cing in direction y. Move the mobile probe along these paths. In Fig. 5.16, pos. 7, the smallest concrete cover measured in a grid field is displayed and stored auto matically as grey scale.

• After having finished one row, press the ↓ key. The cursor jumps to below the last field and the arrow direction changes automatically.

After every manual or automatic change of the

arrow direction, RESET must be pressed. See

also «RESET process», page 10.

• Once the second row at the edge of the measuring area (y-axis) is completed, the cursor jumps to below the last field and the arrow direction changes automa tically. The indicating device operates in the same way if the travel paths are positioned vertically, i.e. if measuring is performed in direction y.

• If a hindrance prevents the measurements, you can shift the cursor by the size of the obstacle.

• Individual values can be deleted by positioning the cursor on the respective value and pressing the PRINT/STORE key for two seconds.

• You can subsequently expand the object opened last in the x and y-direction on new pages comprising 240 measured values.

• For all previous objects, measured values can only be entered in pages that are not yet full.

• If the measurement cannot be started in the top left corner (x and y = 0) you can move the cursor to the starting position using the corresponding arrow keys.

• If you want to reserve pages that will be needed later, each page has to be selected separately. To confirm the reservation you can set a grey scale symbol in the second row using the PRINT/STORE key. The grey scale symbol can be overwritten or deleted at any time.

5.5.2 Measuring with the Universal Probe

Measuring with grid can also be performed with the probe only, i.e. without path measuring (ScanCar). To do this, the x/y-grid has to be drawn on the concrete surface to be measured.

• Carry out the same settings as for «Measuring with the Mobile Probe», page 18.

• During measuring, the grid fields must be scanned with the universal probe.

• Please note that the smallest concrete cover measured in a grid field is always displayed (see Fig. 5.16, Pos. 7). Store this value using the PRINT/STORE key.
