2 Concrete Specific Base Parameters
In the start screen of the device three base parameters for the individual measurement task can be set. Before
starting measurements, the following three configuration parameters need to be set:
Density:
Bulk density
CHAR:
Characteristics of the recipe. 4 setting op-
tions are available:
G Set +/-:
General set
NOTE:
The above settings help with an initial adjustment and may be sufficient under normal conditions, but the
measured values should generally be validated against a reference and if necessary, adjusted using the
parameter G-Set. A reliable reference measurement is necessary for this.
Please take into account that the standard kiln drying measurements also comprise measurement errors.
Concretes that do not meet the specifications according to DIN EN 206-1 and DIN 1045-2 (concretes that tend to
bleed, for example), may lead to significant deviations of the measured values.
2.1 Density
Bulk density, the value from a shatter test, or the density from the mixture calculation can be entered here.
The raw density can be set in steps of +-0.005. Select the correct density value of the concrete sample with the
buttons „+“ or „-“ and confirm it with the button . The SONO-DIS switches back to the CHANGE menu.
Attention:
The setting of the correct raw density is important. The raw density influences the measurement of the water
content inside the SONO-DIS. The difference of raw density between 2.200 and 2.300 corresponds with 8 liter
water. If the raw density of the concrete cannot be determined on site, the input of the set density of the mix
computation would be however a possible compromise to achieve acceptable results. A deviation of +-0.02 of
the density corresponds with +-1.6 liter water.
