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:

: Mass with average moisture content

: 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.
