2. Measuring Principle
2.1 Measuring Principle
The Profometer PM-6 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 the opposite direction. The
resulting change in voltage can be utilized for the measurement.
Coils
Magnetic Field
Concrete
Rebar
Figure 1: Measurement principle
The Profometer PM-6 uses different coil arrangements to generate several magnetic fields. Advanced signal processing allows locating a rebar
as well as measuring of cover and rebar 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 (sphere of approx. 200 mm / 8 inch radius)
will have an influence on the measurement.
NOTE! Remove all metallic objects such as rings and watches before you start measuring.
2.2 Calibrated Measuring with Profometer PM-6
The Profometer PM-6 is calibrated to measure on a normal rebar arrangement; which is an arrangement of non-stainless steel rebars fastened with binding wires only e. g. when measuring on welded mesh
wires the cover and diameter readings must be corrected (see “3.7 Practical Hints”). The following information on accuracy, measuring ranges
and resolutions refer to measurements on normal rebar arrangements.
2.3 The
The measuring range is dependent on the bar size. The expected accuracy of the cover measurement is indicated in the graphic below. It
complies with BS1881 part 204, for a single rebar with sufficient spacing.

Up to the indicated limits the cover is measured and displayed.
In the Locating Mode a rebar is shown. In the Single-Line Mode the cover curve is shown but a
rebar is only set up to 90 % of the maximum cover.

3.1 Getting Started
Battery Installation
To install the Battery (B) into the Profometer Touchscreen Unit (A), lift the
stand as shown. Insert the battery and fasten in place with the screw.

• A complete charge requires <9h (Instrument not operating)
• Charging time is much longer if the instrument is in use.
• An optional quick charger (Part No. 327 01 053) can be used to charge

3.2 Main Menu
On start up the main menu is displayed. All functions may be accessed
directly via the Touchscreen. Return to the previous menu by pressing the
back button or the return icon (arrow) at the top left of the Touchscreen.
Measurement: Application specific measurement screen.
Settings: For application specific settings.
Explorer: File manager functionality for reviewing measurements
saved on the instrument.
System: For system settings, e. g. language, display options.
Information: For device information and remaining storage capacity.
Off: Power off.
Scroll up and down the screen by dragging your finger up or down the
screen. The current setting is displayed on the right hand side. Tap on an
item to adjust it.
1)
For the scanning in Y-direction in the Cross-Line Mode the diameter, respectively spacing for rebars running in X-direction can be set in addition.
2)
Settings can be changed in files already stored.
Measuring Range
Select between Standard, Large or Auto ranges (see Figure 2).
NOTE! The range cannot be changed during the measurement. To change the range, store the data first and open a
new file.
Standard is the default setting, because it is the most accurate one.
Auto switches automatically between Standard and Large. Spot should
be selected for measurements on small areas, in corners and on rebar
arrangements with small spacing.
Rebar Diameter Scan-X / Rebar Diameter Scan-Y
Select the Rebar Diameter (6 to 40 mm / #2 to #12, see Appendix A1),
either determined from the drawing or as measured.
Neighboring Rebar Correction Spacing for Scan-X / Scan-Y
It mitigates the influence of neighboring rebars. By setting the spacing
to the rebars running parallel to the rebar on which the measurement

is taking place, the diameter and the cover are automatically corrected.
This is possible for rebar spacing from 50 to 130 mm / 2.00 to 5.20 inch
(see Appendix A2).
2)
Unit
Select Metric, Metric Japanese, Imperial or Imperial Diameter, Metric
Cover and Distance.
Minimum Cover
2)
A Minimum Cover value from 10 to 142 mm / 0.40 to 5.56 inch can be
set in 1 mm / 0.04 inch steps (see Appendix 3). In the Single-Line, MultiLine and Cross-Line Mode/View rebars with less cover than minimum
cover will be shown in red color. In the Single-Line View and Statistical
View a horizontal, respectively vertical dotted line in red indicates the
Minimum Cover value set.
Cover Offset
2)
When a Cover Offset value is set the measured cover will be reduced by
this value; e. g. when a wooden or plastic plate is used to measure with
the probe cart on rough surfaces (see “3.7 Practical Hints”). In this case
the plate thickness must be set as Cover Offset value). A value from 1 to
50 mm / 0.04 to 1.92 inch can be set.
Display Inclined Rebar
By setting this feature the inclined rebar is displayed in the Locating Mode
when all four wheels of the cart have passed over the inclined rebar. In
the Single-Line and Multi-Line Modes it is only shown in the cart symbol.
NOTE! In areas with small rebar spacing this feature may not
work properly.
NOTE! To get smooth color intervals the Minimum and Maximum Cover should be set in 5 mm / 0.20 inch steps.
Sharpen
2)
With this setting the signal strength color spectrum of the Multi-Line and
Maximum Cover
2)
A Maximum Cover value from 20 to 190 mm / 0.80 to 7.48 inch can be
set in steps of 1 mm / 0.04 inch (see Appendix A3). In the Single-Line,
Multi-Line and Cross-Line Mode/View rebars with cover more than Maximum Cover will be shown in grey color.
NOTE! The Maximum Cover must be at least 10 mm / 0.40
inch higher than the Minimum Cover. If not, the instrument
will correct it automatically.
The Maximum Cover should also be set for different files measured on
the same surface to get the same color range for comparison purpose.
Cross-Line Views can be sharpened.
Display Curve
2)
Select Cover Value, Signal Strength or None. The respective curve or
no curve is displayed in Single-Line View.
Align Rebar Positions
2)
When measuring in the Multi-Line or Cross-Line Mode along at least two
lines of at least 55 cm / 22.00 inch length, the rebar positions of the last
line are aligned to the rebar positions of the two previous lines.
NOTE! This feature should only be set, if the rebars are running
parallel to the Start line (X- or Y-line). It is not activated during
the measurements (activated only when storing the data).

With this feature set, the cursor jumps back to the start line when changing line in the Multi-Line and Cross-Line Modes.
Line Height (in Y-direction)
The line height must be set in the Multi-Line, Area-Scan and Cross-Line
Modes. It determines the spacing between the measuring rows. A height
5 to 203 cm / 2.00 to 80.00 inch can be set.
Grid Width (in X-direction)
The grid width must be set in the Area-Scan and Cross-Line Modes. A
width from 5 to 203 cm / 2.00 to 80.00 inch can be set.
3.4 Measurement Screen
The standard measurement screen is shown on page 3. All settings are
directly accessible from the measurement screen.
Zoom in by placing thumb and index finger together on the
screen and spreading them apart. This can be used in both the
horizontal and vertical directions when making a measurement.
