2.0 MEASURING PROCEDURE

1. Switch on the humimeter BLH by pressing the
power button (

2. Select the right calibration curve for your material
under test using the buttons

3. Place the scale on an even surface. Place the
humimeter BLH in the centre of the scale. Zero the
scale to show 0.0g.

4. Fill the measuring chamber with the appropriate

amount of wood shavings. The cup must be filled
either 50g or 100g material. During filling the cup,
the material must not be compressed too much. If
you have no place in the cup for 100g, the cup must
be emptied again and 50g wood chips have to be
filled into the cup.

CAUTION: Excessive force may be destroyed: the cup!

5. Put the measuring chamber into the device. The

sticker has to be facing the electronics housing.

wheel (1 turn per second) until the LED turns green. Now slowly (0.5 turns per
second) must be rotated until the LED flashes orange once.

7. Then immediately press the start button on the
device

8. After a few seconds, the display shows stable
water content.

9. The water content of the sample is now visible on
the display.

10. If the measure value is blinking, the valid
measuring range is exceeded (limits see list on
page 5). In this case the accuracy will be
decreasing.

12. To name the saved results press the

button.

13. Empty the humimeter BLH and ensure that no
material rests are accumulated in the measuring
chamber.

13.0 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 very 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.

• Wrong filling quantity
Fill in exactly the right weight of wood chips in the measuring chamber.

• Wet or moldy material

• Frozen measuring material

• The steel plate which is mounted on the spindle part has to be cleaned at

regular intervals. As well as the pressure pin on the base plate (use a dry cloth
or something like that). Specifically, after measurement of wet material can be
located on the disk. This material can interfere with the following measurements!

• Compression function has to be done smoothly

To compress the hand wheel approximately one turn per second should be
rotated. When the green LED is on, the hand wheel has to be turned a half turn
further per second until the LED is orange is on.

2.1 Information of the measurement of sawdust

Enclosed you will find instructions for measuring sawdust. If you are not sure what
type of wood you use, we recommend a one-time measurement compared with the
drying method according CEN / TS 14774.

The calibration curves using 100g filling quantity only be used in very wet material.
In general, the sample size of 50gr has to be used. If at the 50gr curve to less
pressure is in the measuring cup (LED don´t lights up orange!), than the 100gr
calibration curve must be used.

Material less than 15% water content cannot be measured.

Information: It is possible that other calibration curves (e.g., other types of wood,
defined mixtures, etc.) are calibrated by the Schaller GmbH in the humimeter
device.

To verify the calibration curve only the standardized drying method is permissible
because many other methods used are doubtful and can lead to incorrect
comparison values. If no existing curve fit, then a calibration by the company
Schaller is required.

4.0 DETERMINATION OF THE MATERIAL REFERENCE MOISTURE

The principle is a comparison measurement with the dehydration method according
to CEN/TS 14961:2005. Take the measured sample and weigh it. Dry it out in an
oven and weigh it again.

10.0 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), otherwise it
can be broken. Plug and remove the insertion probe of your BLH 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.

11.0 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 Checkline Europe (www.checkline­europe.eu) or our dealer.
