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 be
unlocked until the next turn-off of the device. You just have to enter the super­user password.

6.0 MEASURING RANGE

V

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 windo w. 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 grey  invalid
 between 16.0% und 45.0% the value is shown 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
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

4.0 TAKE VALUES

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.
Another important point is that the index points start at the highest moisture
value and run down to the lowest moisture content value.

In order for you to create a curve you need to take several measurements 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 ga uge
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 (
the symbol with the opened door (

) first, and afterwards

).

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. Ho wever, 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% => material
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.

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 not 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 pr obes of your sample
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:

30

TK

28

So the factor is: 1.07 at 5°C
