1.0 GENERAL INFORMATION
In the device different calibration curves are stored. If the material to be measured does not conform to any of the stored curves, a new calibration curve can be created by the customer himself. In the following pages you will find instructions for creating your own calibration curve.
Depending on the material that you want to test it is up to you to select the appropriate drying method and moisture determination. In principle it the setting of your own curve is done assigning a moisture percentage to a reference voltage that is measured by the gauge.
2.0 UNLOCK THE HUMIMETER
In this menu, the hidden functions (grey letters) of the device can temporarily b e unlocked until the next turn-off of the device. You just have to enter the super­user password.
To use this protected features, you have to enter the four digit password. Provided by the factory, this password is the serial number. The four digit serial number is shown in the menu item “status” or when the device is booting.
How to enter the menu point „unlock“: Press the “Rolling menu” button as long as you enter the main menu. Navigate to the menu item „options“ and press the
button. Navigate to the
menu item „unlock“ and press the
button again.
Press the button as long as you have reached the right number and affirm this by pressing the
button. The character will be affirmed and the cursor jumps to the next position. Enter the four numbers of your password and confirm it by pressing the
button.
Press the button and successively to abort the password check. The button also contains a fast forward function, starting when you press the button for a few seconds. The character is affirmed after a few seconds automatically.

6.0 MEASURING RANGE
In the menu item „Valid“ the measuring range of the calibration curve is defined. A valid measuring value is shown in black in the measuring window. An invalid measuring value is shown in grey and is blinking when the water content is out of range.
This feature can be explained best by an example. Wanted is a valid range from 16.0% up to 45.0% water content. Enter the following values in the shown order:
Idx(1) Idx(2) Idx(3) Idx(4) Idx(5) Idx(6)
90.0% 45.1% 45.0% 16.0% 15.9% 0.0% 3 3 0 0 1 1
The measuring range should be defined within the area of the measured samples!
Explanation:
between 0.0% und 15.9% the value is shown in gre y invalid between 16.0% und 45.0% the value is sh own in black valid between 45.1% und 90.0% the value is grey and blinks invalid
7.0 COMPLETION
If all values of the created calibration curve are stored in the humimeter device, you can use the new calibration curve for measuring!

3.0 CHANGE THE CALIBRATION CURVE NAME
If the device is unlocked, the menu point „Materialcalib.“ is available. A list with all calibration curves is shown on the display! Choose an “empty” calibration curve, or a curve you do not need.
Choose the menu item “Name” by pressing the buttons
or and confirm by pressing the button. Your calibration curve name can contain up to ten characters. Enter the name using the buttons or . The name should consist of the filling quantity and the variety (e.g. 2,50k material). If you press the button for a few seconds, the fast forward modus will be activated. If the cursor is in the right position and shows the right letter or character, press the
button. Confirm the
whole name by pressing the
button.
4.0 TAKE VALUES
Select the menu item “water content” by pressing the buttons
or and
confirm by pressing
.
There are 8 index points that make up the curve.
It is IMPORTANT that you do not change the first (1) and last index point (8)!
These values set the measuring range of the gauge within a reasonable limit. For example:
Index point [ldx]
V
oltage Value [V] Moisture Value [%]
1 7.990 0.0 2 4.810 31.0 3 4.800 30.0 4 3.500 47.0 5 2.050 70.0 6 0.452 99.0 7 0.450 99.0 8 0.000 99.0
In order for you to create a curve you need to take several measur ements of material with different moisture contents.

You need to log the voltage and assign a moisture value to this voltage. It is possible to do this live while taking a measurement by p[alcing the gauge on the material. Then you have to press the right button
(„V“). By pressing this button you transfer the voltage value of the sample. If this was successful, you will jump automatically to the next line. The actual calculated water content has to be typed in by hand.
To save the values you have to leave the menu item by pressing the shift button (
) first, and afterwards
the symbol with the opened door (
).
In case you have no moisture content value at the point you take this measurement, it is best you create a list and enter the curve at a later point in time. Both values can be set manually.
There is a maximum of 16 index points available. However, as many calibration points as possible should be affiliated.
With the final calibration curve you can measure up to the driest calibration point you determinate. For example: lowest measured point: 22.0% => materia l over 22.0% water content can be measured!
We recommend that the captured voltage and water contents are inscribed in a graphic. Not linear points can be corrected. The values should be (as shown in the example below) almost on a straight line.
V%
2,878 49,20 2,722 44,90 2,488 41,00 2,311 36,70 2,102 32,50 1,798 28,20 1,600 24,50 1,400 19,10 1,200 15,60
10,00
20,00
30,00
40,00
50,00
11,522,53
To save the values you have to leave the menu item by pressing the shift button (
) first, and afterwards the symbol with the opened door ( ).
To be sure that all values are correct and in the right order, please double check the whole values in the calibration curve!

5.0 TEMPERATURE COMPENSATION
For the temperature compensation a factor is specified by the manufacturer.
In almost all products the entered values will be correct. You do n ot have to change this value in general!
If you however still need to determine some new values, please advance as follows: To achieve a very precise factor take several probes of your s ample with exactly the same water content and pack them into air proof plastic bags (or something else). Now you have to align the samples to different temperatures. One sample at 20°C (68°F), a further at 5°C (41°F) and a third at 40°C (104°F). After the aligning you have to measure the three samples again. IMPORTANT: Let your humimeter also align to the different temperatures.
Using the following calculation you can determinate the temperature compensation coefficient. e.g.: You measure the sample with the humimeter at 20°C and get a value of 30% water content, and the sample at 5°C you measure just 28%. So you can calculate:
So the factor is: 1.07 at 5°C
