1.1.1.2.1 1-Point Calibration

With this material calibration option, a linear equation (f (x) = mx + b) is calculated with the
dry density. So it is necessary to have the dry density of the measured material before
activating this option. A reference moisture content and the tp value (propagation time of the
radar signal) which can be measured or set at the point of the reference moisture. Even if a
polynomial of higher degree is useful for obtaining greater accuracy, the linear equation is
often sufficient to achieve very good results.

Note: To perform a 1-point calibration, you need a material sample as well as the dry density
of the material to be measured. The moisture value has to be determined with another
method like kiln drying or similar, before activating this calibration procedure.

Procedure:

At the beginning of the calibration, the selected
calibration memory (01 - 15) has to be overwritten with
the / buttons. Press the button to accept the
setting and press the button to move to the previous
item.

The percentage reference moisture of the material to be

Note: After performing "Save", the original material calibration is preceded by an "OWN:",

indicating that this is a specially prepared material calibration.

Use the / buttons to toggle between "Save" and
"Discard". The corresponding sub-point is selected with
the key and the key can be used to switch to the
previous point.

1.1.1.2.2 2-Point Calibration

For the 2-point calibration, a linear equation (f (x) = mx + b) can be calculated with two
moisture values of a material and the corresponding tp values (running times of the radar
signal) which are measured or set at the respective material moisture. Even if a polynomial
of a higher degree is useful for obtaining greater accuracy, the straight line equation is often
sufficient to obtain very good results.

Note: In order to perform a 2-point material calibration, you need two material samples

with different moisture values. Moisture values should be determined by
another method like kiln drying or similar, before activating this calibration
procedure. The sequence - "lower moisture value" (more dry material) and
then - "upper moisture value" (moist material) must be observed.

Procedure:

After selecting the menu item "Material cal.", use the
/ buttons to "CHOOSE" one of the 15 stored
material-specific calibrations or "CHANGE" to perform
a new calibration on one of the 15 calibration
memories. The corresponding sub-point is selected

Mode CS: (Cyclic-Successive) For very short measuring processes (e.g. 2…10 seconds)
without floating average and without filter functions, with internal up to 100 measurements
per second and a cycle time of 250 milliseconds at the analogue output. Measurement mode
CS can also be used for getting raw data from the SONO-probe without averaging and
filtering.
Mode CA: (Cyclic-Average-Filter) For relative short measuring processes with continual
average value, filtering and an accuracy of up to 0.1%
Mode CF: (Cyclic-Float-Average) for continual average value with filtering and an accuracy
of up to 0.1% for very slowly measuring processes, e.g. in fluidized bed dryers, conveyor
belts, etc.
Mode CK: (Cyclic-Kalman-Filter with Boost) Standard setting for SONO-MIX for use in fresh
concrete mixer with continual average value with special dynamic Kalman filtering and an
accuracy of up to 0.1%.
Mode CC: (Cyclic Cumulated) with automatic summation of a moisture quantity during one
batch process.

Mode CH: (Cyclic Hold) similar to Mode CC but without summation.
Mode CH is recommended for applications in the construction industry. If the SONO-

probe is installed under a silo flap, Mode CH can measure moisture when batch cycles are
very short, down to 2 seconds. Mode CH executes an automatic filtering, e.g. if dripping
water occurs.
