3 Standard Measurement mode „Average“
Switch ON the SONO-DIS by pressing the button „Measurement“
for approximately 1 second.
During the starting-up process, the SONO-DIS will attempt to communicate with the connected probe. This will
take approximately 4 seconds. If no probe is connected, or the probe is not able to communicate for any reason,
an error message will be generated on the display.
If the probe was successfully detected, the display demands the setting of the individual base parameters.
NOTE:
Should no connection to the probe be possible in spite of several attempts, check if the probe is connected
properly. Should this not deliver a positive result, please contact our service department.
3.1 Conduct a Measurement of the Water Content
If the base parameters are set, press
and the device is in the standard measuring mode “Average”, ready to
measure. „Average“ mode determines the total water content of a fresh concrete sample.
The following display will appear:
remaining battery capacity
Set parameters
Water content
as mean value
Press short:
delete last single value
Press long:
delete whole series
last measured single value
(can be deleted)

Number of measurements
carried out
Standard deviation:
with Std-Dev> 0.5 more individual
measurements are required!
In order to initiate a measurement cycle, shortly press the button “Measurement”
. The measurement
will commence and a turning
-symbol will appear instead of the accumulator-symbol in the upper right-
hand corner. During this period, no other actions can be performed. The measurement requires approximately
2 to 3 seconds. Once the measurement is concluded, the accumulator-symbol will reappear and the measured
values will be generated on the display. The measured water content, calculated considering the raw density is
displayed. The number of measurements “No. Values” is also displayed.
To achieve a best possible result it is advised to make several single measurements at different places inside the
fresh concrete. With smaller grain sizes, up to 5 single measurements can be enough, with concrete tending to
bleed, more than 5 single measurements are necessary. The higher the number of single measurement cycles, the
higher the average measurement accuracy!
