Measuring procedure
1. For a correct measurement please ensure that the device has
the same temperature than the wood chips (+/-3°C). For that
reason, let your humimeter BLL adjust to the surrounding
temperature of the material for at least half an hour before
measuring.
2. Switch on the device: Press the key
for 3 seconds.
3. Change the calibration curve: Press one
time the key and then the or key.
The name of the calibration curve can be
seen at the head of the display.
4. Plug the probe of your humimeter BLL
straight into the wood chips. It is not
allowed to load the measuring head
incorrect or drop it down!
5. Now the display shows the water
content. Left hand the temperature of the
material is displayed.
6. To save the results in the save menu
press the ( button). The storage was
successful when the number in front of
the symbol increased. To reach the
store menu please press ( ) until the
appears.
7. To name the saved results press the
button.
Risk of injury by measuring head! Keep away from children!

Wood chips: standard chips of wood (forest wood chips)
according to standard EN ISO 17225-1 class P16, P31 and P45.
Coarse chips: for coarse wood chips P45 or P31 but with
fewer fines.
Industrial chips: for industrial chips of wood without barks and
fines (similar P45 or P63)
Definition of wood chips classes (according EN ISO 17225-1)
The stated numbers refer to the particle size that goes through
round gaps of the corresponding diametres (e.g. P16: 16 mm).
oP16 minimum 75% of the bulk is between 3.15 and 16 mm
oP31 minimum 75% of the bulk is between 8 and 31.5 mm
oP45 minimum 75% of the bulk is between 8 and 45 mm
oP63 minimum 75% of the bulk is between 8 and 63 mm
Compression of wood chips
The humimeter BLL is calibrated for normally compressed wood chips. If the
measured wood chips are compressed to a much lesser or greater extent,
this will cause measuring imprecisions. Normally compressed wood chips
are defined in norm EN 15103 (determination of the bulk density).
Determination of the material reference moisture
The principle is a comparison measurement with the dehydration
method according to EN 14774. Take the measured sample and
weigh it. Dry it out in an oven and weigh it again.
Mn: Mass with average moisture content
Mt: Mass of the dried sample
%F: Calculated absolute moisture

Device maintenance instructions
To provide a long life of your device please does not expose it to
strong mechanical loads or heat e.g. dropping it or direct sunlight
exposure. Clean your device using a dry cloth. Any kind of wet
cleaning damages the device.
It is not allowed to load the measuring head incorrect (stress,
bending), other wise it can be broken. Plug and remove the
insertion probe of your BLL straight into the wood chips.
The instrument is not rainproof. Keep it in dry areas. When the
device isn’t used for a longer period (2 months) or when the
batteries are empty, they should be removed to prevent a leakage
of the battery acid.

Transfer saved data to the PC
(Only possible with humimeter USB
interface module)
To send your saved logs to the PC, connect
the humimeter device to your PC using the
USB cable that was delivered with your
device. Carefully loose the protection cap on
your humimeter and plug in the USB mini B
connector. The bigger connector has to be
connected to a USB slot on your PC.
Start the LogMemorizer software on your
PC and switch on your humimeter BLL.
The data transfer can be started on your
humimeter or on the software.
Starting the data transfer on the humimeter:
Press the key until you reach the menu
(see image on the right). Then choose
„Send Logs“ and confirm by pressing the
key. Now choose „Manual Logs“ and
confirm with again. All saved logs will be
sent to your PC.
Starting the data transfer on your PC:
Press the button „remote control“ in the
LogMemorizer software. A drop-down menu
with several options opens (see image
below).
For transferring the data you can select
„Import last manual log“ (the last saved
measuring series is transferred) or „Import
all manual logs“ (all saved logs are
transferred).
If you click on one of these menu items, the
transfer starts immediately.
For the basic adjustments of the software
please look through the instructions on the
LogMemorizer CD.

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 our
dealer.

page 12 Version 2.4_en
Most common reasons for miss readings
Product temperature out of application range
Material below 0°C resp. above +40°C (32 to 104 °F) 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.
Not adjusted material under test
Please ensure that the device and the material under test are
being stored at the same temperature (+/-3°C) before
measuring. A high temperature difference has a negative
effect on the stability of the measurement results.
Wrong calibration curve
Before you measure your sample, double check the correct
selection of the calibration curve.
Wet or mouldy material
Frozen measuring material
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 measurement. After measuring wet material clean
both plastics parts accurately with a dry cloth.
It is not allowed to load the measuring
head incorrect (stress, bending), other
wise it can be broken. Plug and remove the
insertion probe of your BLL straight into the
wood chips.
Do not move the BLL crosswise to the
insertion direction after plugging in.
Do not drop the measuring head or use it for
any ulterior purposes.
A broken measuring head is no case of
warranty!
