4 In 5 steps to a successful measurement
There should be no metal parts around the probe head of SONO-WZ during the measurement procedure, because
metal can influence the electrical field. Best and easiest way is to use a plastic bucket filled with fresh concrete.
To avoid air gaps the concrete should be compressed by several stamps of the bucket on the ground. The probes
surface must be clean and free of concrete crusts and if necessary the probes surface must be cleaned with a
wire brush. During measurement the probe head of the SONO-WZ must be completely immersed inside the fresh
concrete.
Step 1: Switch-On the SONO-DIS
By activating the button for longer than one second, the SONO-DIS starts with the measure mode.
Step 2: Adjust the Raw Density, CHAR-parameter and G-Set (Reference is made to Chapter 7 “Concrete Spescific
Base Parameters”)
Density:
Raw Density
CHAR:
Characteristic of the recipe
G Set +/-:
If you want to measure the complete
water content (the total kiln drying water content)
with SONO-WZ, the G-Set is to be entered with a
plus value, with 1/3 of the core water!
If the base parameters are set, press and the device is in the standard measuring mode “Average”, ready to
measure.
Step 3: Insert the probe SONO-WZ in the fresh concrete and start the measurement
The probe head should be placed inside the concrete with a slight angle, at the edge of the bucket.
For very liquid concretes: Use the covered plastic shovel. Press the probe tip with the black ceramic window in
front side, slowly and diagonally to the opposite side of the bottom of the bucket, so that the probe lies diagonally
in the bucket with the handle of the probe on the edge of the bucket. This ensures that a representative concrete
mixture lies on the probes surface. For stiffer concretes: Compress the concrete by several knockings at the bucket
with the foot. Start the measurement by shortly pressing the button “Measurement”
