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.
