Moisture meter type DS5-AL
The measuring electrode of the meter is pushed into the paper or
cardboard piles and a high frequented field is able to pass through the
material. Taking in account the material setting, the percentage water
content is determined. The result can be read off immediately.
Method of operation:
Measuring principle:
The meter works in accordance with the principle of an opened plate
capacitor. The capacity of the capacitor depends on the material-
(dielectric)-constant of the material in between the plates. Compared with
air (e = 1) , for example water has a very high dielectric-constant (e = 80).
rr
The water content of a wet material can therefore be determined by
determining the dielectric constant of this material.
Safety tips:
- follow the operating instructions
- only use the meter as directed (see page
- keep the meter away from live and current carrying parts
- keep the meter dry
- avoid impacts
- protect the meter from heat
- keep the meter dry and try to prevent dirt from entering the case
- protect the meter from electrostatic discharge.
- the meter must be repaired or serviced only by qualified specialists
Damages caused by failure to follow the above mentioned Safety tips
are not covered by the warranty!

Storing of Moisture Values:
If the storage is activated, by pushing the OK-button up to 250 values can
be stored. If the storage parameter is set to “on single” always one value is
stored, if the parameter is set to “on auto” every value > 0 is stored
automatically until the storage is full or the OK button is pressed again. The
number of measurements per second (mps) can be adjusted between 1 and
10. The storage procedure will be signed with an “stor” on the botom line at
the right side.
Restorage of the Stored Values:
By pushing the "OK" and the “arrow down” button, the stored values can
be restored. The result is shown in 2 colums. On the left average
value(AV), Minimum value (MI) and maximum value(MA) and on the right
side the stored values, they can be scrolled with the arrow buttons.
With our optional PC-interface cable and software DMI-Controller the
stored values can be transfered to a PC for storing them into a file or
showing them on a graph.

Cancellation of the Stored Values:
After changing the material adjustment or with code 14, the stored values
will be cancelled, which is shown as “delete storage” on the display.

Parameter Settings:
With code numbers parameter settings can be changed. Press both arrow
buttons, the display shows “code:00“, adjust the required code with the
arrow buttons and confirm it with OK. The following parameters are
changeable:
code 11: storage adjustments (OFF, ON single, ON auto)
ON single: single values will be stored by pressing the
OK-button
ON auto: All values > 0 will be stored automatically after
pressing OK until the storage is filled up or until the OK-button
is pressed again.
code 12: number of measurements per second (mps)
range 0 - 10
code 13: number of measurements until automatic switching off (loops)
range 0 - 999, loops = 0: no automatic swiching off
code 14: delete storage, through changing the material setting the
storage will be deleted too.
code 15: select language
code 21: attenuation ( brake), range 0 - 99
code 22: automatic maximum value measuring (automax)
no automatic maximum measurement (float)
code 95: toggle between material moisture and calibration
measurements (display of input values)
code 97: starts the calibration procedure
Turn Off the Meter:
- push "ON/OFF" button until the display shows the service address, this
keeps in the display as long as the “ON/OFF”-button is pressed
- release "ON/OFF" button: the meter turns off
If no measurement is carried out for an adjustable time,
the meter turns off automatically.

Basic Calibration:
start calibration procedure with code 97
1. zero point
The zero point only can be tested, not adjusted. On the display the zero
point (NP) and the actual measuring value (UM) are shown. At the test
the sensors have to be clean and dry! The instrument has to be hold free
into the air. Than wait till NP and UM are nearly equal. The value should
be between 10 and 390. Is UM <1 or > 400, then no zero point
calculation is working, in this case the instrument needs to be repaired.
With the OK-button to the next calibtration step.
2. measuring in test module PE50R at high amplification
As shown on the picture, the instrument has to be sticked into the test
module.With the arrow buttons the factor (F) can be changed till the
display shows MV=200.
With OK-button to the next step.
3. measuring in test module PE50R at low amplification
With the arrow buttons the factor (F) can be changed till the display
shows MV=200.
With OK-button the changed factors will be stored.
The factors can be changed in the range 150 - 255. If this is not enough, the
instrument needs to be repaired.

Oven Drying Method:
The oven drying method is the most accurate way to measure the material
moisture in paper NORM EN20 287 or DIN ISO 287or wood DIN 52183.
We recommend this for testing and calibrating of our moisture meters.
Short description:
- for measuring the weights we recommend a balance with an measuring
range of 200g and an accuracy of 0,01g
- For drying you need an oven with adjustable temperatures of 105°C
- Take a sample from the waste paper, avoid border parts. The sample
should be at least 20g
- It is very important to take the first weight of the sample immediately, as
air humidity may change the moisture content.
Name of the first weight: wet weight (WW)
- The probe must be dried in the oven until the weight is constant,
the maximum drying temperature: 105 °C (ISO 287),
- the name of the dry weight is DW
- moisture calculation:
DIN 52183: MOISTURE = 100% * (WW - DW) / DW
DIN ISO 287: MOISTURE = 100% * (WW - DW) / WW

Customer Specific Linearisation Curves:
It is possible to store 10 special linearisation curves with up to 8 free
programmable points each. The values in this storage will stay in the
memory during replacement of the battery. The adjustemt of the calibration
points can be done with the PC-software DMI-Controller, or they can be
changed through the kexpad as decribed below.

The microcontroller in the meter takes the analog measurement value with
automatic zero point correction.
The resulting value is our input value.
You can display the input value with code 95. 1:0000
According to a rectangular coordinate system, the input are assign in the X-
direction
and the moisture result are assign in the Y-direction.
According to this, X-values are input values ,
Y-values are the assigned moisture values.
X-values (input values) can appear in the area 0-4095,
this input values ( can be dedicated to moisture values (Y-values)
The moisure values have to be written in %-values * 10
(for example: for the moisuture value 12,3 % ==> Y-value = 123).
For chaging the calibration points you need to put in code 40 to 49 for
curve 0 to 9 (e.g. code 43 for curve no. 3).
The values signed with “<” can be changed with the arrow keys.
Confirm the changed value with “ok”, then you can change the next value.

The maximum value for the input value is bewteen 4000 and 5000,
depending on the basic calibration factor.

With code 30, the special curves can be selected.
