Measuring procedure:
1. Place the empty provided cup (0.25 litre)
on the scale and turn it on. The scale
shows 0.0 gram.
2. Make sure that the measuring chamber is
completely empty. It is important that no
material is left in the measuring chamber
when you turn on the device.
3. Switch on the device by pressing the
power button ( ) for 3 seconds.
4. The next step is the self calibration. The
word “reinitialize” will show up on your
display. Accept by pressing the
button.
5. Select the right calibration curve for your
material under test using the or
buttons.

Version 2.4_en page 3
6. Fill up the cup with the sample material (+/-
0.5g). The filling quantity needed is shown
on the upper left corner on the display of the
device.
7. Fill up the measuring device with the sample
material. The filling needs to be done slowly
and constantly to ensure reproducible
results. There must not be used a funnel or
anything similar for filling.
8. The display shows the measuring result.
9. If the measuring value is blinking, the valid
measuring range is exceeded (limits see list
on page 5). In this case the accuracy
decreases.
10. Empty the humimeter and ensure that no
grain rests are accumulated in the
measuring chamber.

Changing batteries
If the batteries are empty, please proceed as follows:
1.) Press with your finger onto the arrow of
the battery cap und pull it back.
2.) Remove the empty batteries.
3.) Put four new 1.5 Volt AA Alkaline
batteries in the device. Check the right
position of the battery poles.
4.) Press down the batteries and close the
cap.
If the battery symbol appears in the measuring
window resp. if a critical charge of battery is
shown in the status, the batteries have to be
changed IMMEDIATELY.
Also remove the batteries if you do not use your
humimeter device for a longer period. For
eventual resulting damages we cannot provide
any warranty.
Determination of the material reference moisture
The “humimeter FS1” determines the water content that means the
moisture is calculated in relation to the total mass:
M
n
: Mass with average moisture content
M
t
: Mass of the dried sample
%F: Calculated moisture content
(corresponding to norm EN ISO712)

Exemption from liability
For miss-readings and wrong measurements and of this resulting
damages we refuse any liability.
This is a device for the quick determination of moisture. The
moisture depends on multiple conditions and multiple materials.
Therefore we recommend a plausibility check of the measuring
results. Each device includes a serial number and the guarantee
stamp. If those are broken, no claims for guarantee can be made.
In case of a faulty device, please contact Schaller GmbH
(www.humimeter.com) or our dealer.

! IMPORTANT ! please read
Most common reasons for miss readings
•Product temperature out of application range
Material below 0°C resp. above 40°C may cause faulty
measurements. The storage of cold material in a warm
storage area usually creates condensed water, which leads to
major measuring errors.
•Not adjusted material under test
Let your humimeter adjust to the surrounding temperature of
the material for approx. half an hour. A very high temperature
difference has a negative effect on the stability of the
measurement results.
•Wrong calibration curve
Before measuring your sample, please double-check the
correct selection of the calibration curve.
•Wrong filling quantity
Fill in exactly the right weight (± 0,5 gram) of material into the
measuring chamber.
•Wet or mouldy material
•Stored and fermented corn silage from whole grains may
lead to higher value
•Frozen measuring material
If the material is frozen, the accuracy decreases significantly.
Device maintenance instructions
To provide a long life of your device please do not expose it to
strong mechanical loads or heat e.g. dropping it or direct sunlight
exposure. Clean your device using a dry cloth. The measuring
chamber needs to be cleaned with a dry and soft brush.
Any kind of wet cleaning damages the device. The instrument is
not rainproof. Keep it in dry areas.
When the device is not used for a longer period (6 months) or when
the batteries are empty, remove the batteries to prevent a leakage
of the battery acid.
