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
measured, must then be set with the / buttons.
Press the button to accept the setting and press the
button to move to the previous item.
In the following step, the dry density of the material to
be measured must be set with the / buttons.
Press the button to accept the setting and press the
button to move to the previous item.
In the next step, the tp value (radar signal time) has to be determined by a measurement with
the connected probe or by manual setting with pre-determined tp values.

In the last step, the calibration settings can be saved with "Save" to the previously selected
calibration memory location, or can be canceled with "Discard".
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
with the key and the key leaves this menu point.
