1 Introduction
PM8000 Pro and PM8000 are high quality instruments used to locate rebars, measure
concrete cover of rebars and estimate rebar diameters in concrete structures.
The product consists of
 the PM8000 high-performance sensor,
 the pm iOS app
 and the Screening Eagle Workspace platform.
Figure 1: PM8000 System
The PM8000 sensor can be used in two different configurations:

1.3 Product applications
In general, two measurement types can be differentiated:
 Spot measurement (standalone)
For brief quality control, rebar location or metal detection a spot measurement is
performed.
Spot measurements are done in standalone configuration and provide measurement
values, such as concrete cover. For a sequence of spot measurements, the pm app can
be used to collect elementary statistics and to attach additional information such as
pictures, geolocation to the measurement series.
 Scan measurement (connected, only for PM8000 Pro)
For durability & structural resistance assessment, quality control, mapping of concrete
cover, determination of rebar spacing & diameter values a scan measurement is
performed.
Scan measurements are producing numerical and visual measurement data, conclusive
statistics. The measurement data can be visualized in various form, e.g. in an informative
heat maps. Additional data such sensor information, pictures, geolocation ensure
professional documentation of the measurement.

2 Scope of Delivery
Please refer to the Quick start Guide provided in the standard delivery and available in
download section of the product webpage:
profometer-pm8000-QSG.pdf (screeningeagle.com)

17. April 2023 © Copyright 2023, PROCEQ SA 10
3 Measurement Principle
PM8000 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 induced.
They produce a magnetic field in the opposite direction. The resulting change in voltage can
be utilized for the measurement.
Figure 3: Measurement principle
PM8000 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 concrete1, 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.
Remove all metallic objects such as rings, watches, and all electromagnetic wave
generators (smartphones, high voltage equipment etc.) from the area before you start
measuring!
1 Some concrete types and other structural materials may have metallic content.

In the menu the function keys can be used to navigate through the menu items:

17. April 2023 © Copyright 2023, PROCEQ SA 15
4.6.1 Main Menu Items
Several menu items are available for changing the settings, configurations and access to the
device information.
Figure 12: Menu item overview
4.6.2 Setting Reference Rebar Diameter
With the correct rebar diameter setting, the precision of cover measurement and rebar
diameter estimation increases significantly.
In this menu you can set the real rebar diameter value, it’s known from construction data (BIM,
as-built drawings) or inspection hole.
If the rebar diameter is unknown, then keep the default diameter of 16 mm / #5
Figure 13: Menu - Setting rebar diameters

17. April 2023 © Copyright 2023, PROCEQ SA 16
4.6.3 Set Operation Mode
In standalone operation, it is important to select the right mode before spot measurement.
In this menu you can select on the three different modes:
 Locate:
Rebar location, measurement reading, metal detection
 Spot Scan Auto:
Any measurement is stored automatically (without pushing any button).
 Spot Scan Manual:
Any measurement is stored manually by short pushing Left Side Key
For both spot scan modes: if the rebar diameter is measured then the value is also stored
along the displayed cover value stored automatically or manually.
Create a new series or switch mode for stopping a series.
Figure 14: Menu – Operation Mode
4.6.4 Set Minimum Cover Alert limit
Having a cover alert allows the user to identify the insufficient cover areas.
In this menu you can set the minimum cover alert limit. The measurement center LED is lit
when the cover is below this limit. If audio is on (see section 4.6.7), an audio signal is
generated.
Having a cover alert allows the user to identify the insufficient cover areas.
Figure 15: Menu - Minimum cover alert limit

17. April 2023 © Copyright 2023, PROCEQ SA 17
4.6.5 Neighboring rebar correction
Cover and rebar diameter measurements are influenced by neighboring rebars. This can be
compensated by using the Neighboring Rebar Correction (NRC).
In this menu, you can activate the neighboring rebar correction by setting the known rebar
spacing.
Please note, that this only works correctly, if the rebar spacing of first rebar layer(=mat)
is under 130mm / 5.2 inch.
If you do not know the rebar spacing, you can measure it manually by locating several
1st layer rebars, or get it from the construction data (BIM, as-built drawings) or inspection
hole.
Figure 16: Menu - Neighboring Rebar Correction
4.6.6 Measuring Range
The pulse induction principle used by PM8000 has defined operating ranges and accuracies.
The measuring range is dependent on the rebar size. The expected accuracy of the cover
measurement is indicated in section 4.8 .
In this menu you can select the right measuring range depending on the rebar or metallic object
depth:
 Standard : <80mm / 3.15 inch (Default)
 Deep : from 80mm to 180mm / 3.15 inch to 7.10 inch
 Auto : Switches automatically from Standard to Deep
Rebar diameter estimation can be performed only in Standard measuring range because
of depth limitation, it cannot be performed in Deep measuring range!

17. April 2023 © Copyright 2023, PROCEQ SA 18

4.6.9 Memory
The PM8000 sensor has a memory capacity of 50 measurement files.
When the memory capacity is full, a warning icon is visible (as described in section 4.4).
The user has then 3 choices:
1. Do nothing. Any new spot measurement series will overwrite an existing one.
2. Manually delete all spot measurements series as explained in Figure 20.
Figure 20 : Menu – Memory
3. Connect to pm app installed in an iPad to import all the spot measurement series. This
automatically deletes all measurement series from the sensor memory. Given mobile
data connectivity (Wifi or mobile network), the pm app automatically and safely stores
all spot measurement series on the Screening Eagle Workspace by synchronizing with
the iPad.
