Packaging
The paperboard cylinder (or optional the wooden case), where your
device has been delivered, should be used to store your device
when it is not in use. Don´t dispose the packaging. In case of
warranty you have to return the device in this board cylinder. In
case of damage during the transportation in another packaging the
customer takes the responsibility.

Measuring procedure
1. For a correct measurement please ensure that the device has
the same temperature than the material you want to measure
(+/-3°C). For that reason, let your humimeter FL1 adjust to the
surrounding temperature of the material for at least half an hour
before measuring (protect from direct
sunlight!).
2.) Switch on the device: Press the key for 3
seconds.
3.) To change the calibration curve, please press
the or key.
4.) Plug the probe into the material. The display
shows the water content immediately.
5.) Pay attention to the direction of plugging in!
(pay attention to the following page!)!
6.) If you press the very left button (Hold button
), the measuring value remains on the
display until you press a button again.
ATTENTION! Risk of injury!

Direction of plug in
Insert the device into the bale like shown in the picture below. Any
other direction of plugging lead to a significant deviation of the
measuring results. Pull the unit straight out again. Any mechanical
damage due to mishandling is no case of guarantee.
Round bales have to be measured on the face side. Measurements
at the bearing surface lead to miss readings.
Rectangle bales have to be measured on the face side.
Measurements at the other side can lead to miss readings.

Changing the User level
switching from simple user to advanced user:
Directly after switching on the device, keep both the and
buttons pressed as long as the logo is shown at the display.
The device starts the main menu automatically. Navigate to
“Options”, then “oUserlevel” and confirm by pressing . Finally you
have to enter the super user password using the button (factory

Changing batteries
Your new device is provided with batteries.
Please find enclosed the manual for
changing of batteries:
1.) At first remove the rubber protective
housing. For that, hold the rubber
housing at the upper side and pull it
over.
2.) Press with your finger onto the arrow of
the battery cap und pull it back.
3.) Remove the empty batteries.
4.) Put four new batteries in the device.
Make sure that the position of the
battery poles is correct.
5.) 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. If you do not use your
humimeter device for a longer period, remove the
batteries. For eventual resulting damages we
cannot provide any warranty.
Determination of the material reference moisture
The humimeter FL1 determines the water content, that means that
it calculates the moisture referred to the total mass:
M
n
: Mass with average moisture
content
M
t
: Mass of the dried sample
%F: Calculated absolute moisture
(water content) (according to
norm: CEN/TS 14774)

page 7 Version 1.6_en
Exemption from liability
For miss-readings and wrong measurements and of this resulting
damage we refuse any liability.
This is a device for 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 your 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 may lead
to major measuring errors.
•Discrepancy in temperature between device and material
Please ensure that the device and the material under test are
being stored at the same temperature (+/- 3°C) before
measuring. Protect your measuring device from direct sunlight
for a reasonable time period before taking a measurement. A
high temperature difference has a negative effect on the
stability of the measurement results.
•Wrong calibration curve
Double check the correct selection of the calibration curve
before measuring.
•Wet or mouldy material
•Frozen measuring material or material containing snow
This leads to a major decrease in accuracy.
•Direction of plugging in
The Direction of plugging has a great influence on the
accuracy. Necessarily follow the instructions according to the
beginning of the manual!
•Compressed density outside the application range
If the compressed density differs from that specified, there
may be deviations!
•Moving the measuring head after the plug in leads to miss
readings!
•Water film at the measuring head
After measuring wet material a water film can arise on the
sensor head. This could lead to a too high result in the
following measurements. After measuring wet material clean
both black plastic parts of the measuring head accurately with
a dry cloth.
ATTENTION: Risk of injury by measuring head!
Keep away from children younger than 16 years!
