7.5 Configuration and measurement
For the device to be able to display the water content as a kiln-dried value with a required
accuracy of ±1 to 3 l/m3, the system must be set beforehand to a specific "concrete
formulation characteristic" and to the rock used. This setting is made using the CHAR and
G-Set parameters.
7.5.1 CHAR parameter for the concrete formulation characteristic
With its radar measuring field, the SWZ probe shows the dependency of the grading curve
on various concrete formulations. Therefore the handheld device offers users 4 different
possible settings, which can be entered as a CHAR parameter.

1 Fine (grading curve C)
2 Normal (grading curve B)
3 Coarse (grading curve A)
4 Special (gap-graded U)
Fine (grading curve C)
The probe measures slightly too little water and therefore has to adjust the water content
upwards slightly
• Concrete with a high mortar content, i.e. a very high quantity of sand, particularly with a
high fines content, a high quantity of cement
• Standard admixtures, standard additives as well as perchloroethylene (PCEs)
Normal (grading curve B)
No or minor correction
• Constant and relatively well-distributed grading curves
• Standard admixtures, standard additives as well as PCEs
Coarse (grading curve A)
The probe measures slightly too much water and therefore has to adjust the water content
downwards slightly
• Concrete with higher k-values and low mortar content
• Concrete with constant and relatively well-distributed B-grading curves with one
peculiarity: low target water content that is less than 160 l/m3, and large amounts of
superplasticizers (PCE) which improve general flow characteristics/rheology.

Solitrend MMP20 (Option D) Commissioning
Endress+Hauser 17
Special (gap-graded U)
The probe measures slightly too much water and therefore has to adjust the water content
downwards slightly
• Very little or no gravel of size 2/8mm or 4/8mm
• Standard admixtures, standard additives as well as PCEs
7.6 General G-Set parameter
The probe measures both the free effective water in fresh concrete and a share of the core
water or absorbed water. While there are types of rock that absorb very little core water,
there are aggregates, such as sandstone or lime grit, that can absorb up to 50 l of core
water. The core or absorbed water is not used to bind the cement and is therefore not
processed for the w/c-ratio.
7.6.1 The SWZ probe measures three types of water
In principle, the probe measures the water parts as the kiln-drying method
The free water
The free water in the concrete mix which enters into the calculation of the w/c-ratio. This
water is the actual value that is sought when using the probe.
A share of the core water
Water that is absorbed by the aggregates. The probe can only measure a percentage
(approx. 1/3) of this core water. The core water can be 10 to 35 l/m³ depending on the
type of rock. This (correction) value is represented in the G-Set parameter (approx. 2/3 of
the core water), depending on the formulation and rock. The G-Set value is typically
approx. –10 l/m³ assuming a core water content of 15 l/m³. These –10 l/m³ are then
automatically subtracted from the measurement in the handheld device so that the
reading in the handheld device matches the effective water content. See also the chapter
on "Core moisture, core water and absorbed water".
Additives
Additives that behave like water are also measured by the SWZ probe. This must be taken
into consideration.
For the G-Set parameter, it is therefore necessary to adjust the probe (one time only) to
the type of rock that is used, which depends on the concrete formulation. To be able to
display the effective (or kiln-dried) water content in the handheld device, it is necessary to
factor in a value for the "G-Set" parameter for the formulation used with the type of rock.
This value must be determined once.
If the water content that the probe displays for a special concrete is too high, G-Set must
be adjusted by the corresponding number of liters. The exact G-Set value to be factored in
for the concrete formulation with the rock type (location) and entered into the handheld
device can be verified or determined in two ways:
• By comparing the probe measurements with several correct values for the water content
of the concrete, for example by mixing concrete with dry aggregates.
• By comparing the probe measurements with several correct (!) kiln-dried values after
kiln-drying. It is important to take the possible sources of error into consideration during
the kiln-drying process.
The kiln-dry water content is calculated as follows:
Kiln-dried value = effective water + core water + additives that behave like water. See
also the chapter on "Core moisture, core water and water absorption".

7.7 Setting or changing the three concrete formulation
parameters
7.7.1 Changing or entering the raw density
Values must first be entered for the configurable parameters before the handheld device
can switch to the measurement mode to measure the water content.
1 Raw density D
2 Characteristics
3 General-Set
Characteristics of the concrete formulation with 4 possible settings: coarse A (minus
correction), normal B (no correction), fine C (plus correction), or special U (minus
correction for gap grading). Note: This parameter is significantly influenced by the mortar
content in the concrete.
General-Set: Fine adjustment of the probe to concrete variety with rock type and core
water. Entry max. ±50 l typically: –10 l (2/3 of core water) which are automatically
subtracted during the measurement if the effective water content (the effective water) is
to be measured.
If the kiln-dry water content is to be measured with the SWZ probe, enter a positive
value for the G-Set, with 1/3 of core water!
Entering the raw density
1. The first parameter to be configured is the raw density, which can be set in
increments of ±0.005. Ideally, the raw density is set correctly in the handheld device
before the measurement of the water content
2. Set the density value D of the fresh concrete, which is determined with a concrete
specimen, with the navigation keys
3. Press Enter to confirm your entry
 This automatically takes you back to the "Change" menu
It is important to enter the raw density value, as it is used directly to calculate the
water content. If the raw density cannot be determined on site, it is also possible to
enter the target raw density in order to obtain acceptable measurement results. A
density deviation of ±0.02 would mean an error of ±1.6 l in the water content
measurement. A difference of 0.1 in the raw density, i.e. from the density value 2.200
to 2.300 means a water content difference of 8 l!
7.7.2 Setting the CHAR formulation characteristic
The CHAR parameter is entered by activating one of the four possible settings:
• Fine C
• Medium B
• Coarse A
• Gap U
The CHAR parameter is significantly influenced by the mortar content in the concrete.

Solitrend MMP20 (Option D) Commissioning
Endress+Hauser 19
Entering the CHAR parameter
1. Using the navigation keys , select one of the four possible options for CHAR (fine
C, medium B, coarse A, or gap U)
2. Press Enter to confirm your entry
7.7.3 G-Set fine adjustment for concrete variety with rock type and
core water
The G-Set value is entered in liters/m3 and can be entered in increments of 1 l/m3 up
to a maximum of ±50 l/m3. Once a G-Set value is identified for a certain type of rock,
it is advisable to archive this value
Entering the G-Set value
1. Using the navigation keys , set the G-Set value in increments of 1 l/m3 up to
maximum ±50 l/m3
2. Press Enter to confirm your entry
 Once you have changed or set the raw density, the CHAR parameter and the G-
Set, you are taken automatically to the "Meas" menu when you press the Enter
key .
7.7.4 Measuring in the "Average" operating mode
The following screen appears in the "Meas" menu once the raw density and G-Set values
have been entered. The handheld device generally measures in the "Average" mode and
determines the kiln-dry water content of a fresh concrete sample in liters/m3 using the
raw density entered.
Starting a single measurement
1. Press the Enter key briefly
 The device starts the single measurement and a rotating symbol appears instead
of the battery symbol in the top right-hand corner for the duration of the
measurement process. No other actions can be performed during this time. A
single measurement takes around 2 to 3 s. When the measurement is finished,
the battery symbol appears on the display again.
2. The water content, calculated using the raw density D, is displayed in liters/m3 on the
screen. The number of individual measurements is displayed below this value in "No.
values".

5 Remaining battery
6 Water content as an average value
7 Last single measurement (can be deleted)
8 Number of measurements performed
• To obtain a representative value for the material mix, take at least 5 individual
measurements (see Measurement cycle for SWZ probe).
• In the case of concretes that tend to bleed, taking a higher number of individual
measurements increases the accuracy and ensures a more representative value.
• Large gravel pieces directly at the surface of the probe can affect a reading; a lower
water content is measured, for example.
• Incorrectly mixed concretes are difficult to measure with the probe.
Measurement quality:
The standard deviation StdDev displayed by the handheld device reflects the quality of the
reading. If the StdDev value is >0.5, the concrete mix is too heterogeneous; more single
measurements are required. At least 6 single measurements should be taken and a StdDev
of 0.1 to 0.5 should be displayed before you can stop taking single measurements and
accept the measured value as the final result.
It is very difficult, however, to achieve a StdDev of <0.5 for very heterogeneous concrete
(e.g. concrete that bleeds significantly).
Smileys on the display screen indicate whether the standard deviation is good, acceptable
or not acceptable:
• good (<0.2)
• acceptable (0.2 to 0.49)
• not acceptable (>0.5)
The handheld device automatically filters out water content values that are less than
100 l/m3. For example, if the start button is accidentally pressed during a measurement
series or if the probe was not yet fully introduced into the concrete.
Values that are too low are flagged with a warning sign and are not used to calculate
the average.
The measurement series can be cleared by pressing the navigation key and the
handheld device is then ready for a new measuring cycle.
7.8 EC-T: a parameter for cement analysis
The EC-T parameter is displayed on the screen. With the TDR measurement method, the
electrical conductivity (EC-T) of the concrete is determined using high-frequency
attenuation of the radar pulse, making it possible to assess the cement content or cement
type. The displayed EC-T parameter can be interpreted as a preliminary value for the
cement content or cement type during single measurements, thereby ensuring enhanced
