1.0 MEASURING PROCEDURE

1. Place the scale on an even and sturdy work surface.
Place the BM1 in the centre of the scale. Zero the scale
to show 0.00kg.

2. Fill the supplied 13 litre bucket with samples taken from
varying locations in sample storage.

3. Check 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.

4. Switch on the BM1 by pressing the power button

for

3 sec.

5. As the next step, please do the self calibration. The
word “Reinitialize?” will show up on your display. Accept

by pressing the

button.

6. The self calibration is finished when the display shows
the measuring window.

7. Fill the measuring device with the sample evenly
distributed to ensure reproducible results.

8. Remove material till the next lower weight range is
reached. If only a little missing (e.g. 0,10kg) to the next
higher level, it should be filled up to that stage. The
actual weight is shown on the scale.

10.0 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
Let your BM1 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 you measure your sample, double check the correct selection of the

calibration curve.

• Wrong filling quantity
Fill in exactly the right weight (± 0.01kg) of wood chips in the measuring

chamber.

• Wet or mouldy material

• Frozen measuring material

11.0 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. 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, they should be removed to prevent a leakage of the battery
acid.

8.0 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 Electromatic (www.checkline.com).

the material in the measuring chamber must be the
same as the calibration curve.

The display shows the water content.

11. 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. If you are
measuring wood chips, select the next higher weight
class and refill wood chips to reach the higher filling
weight.

14. Empty the BM1 and ensure that no material rests are
accumulated in the measuring chamber.

Measuring process of wooden pellets:

Measure wooden pellets with the calibration curve “5,000kg pellets”. For this
measurement the bucket not has to be full of pellets, you must fill in 5,00 kilograms
of wooden pellets every time.

Measuring process of dry wood-shavings:

Is the 13 litre bucket not big enough for 1,00 kilogram of shavings, the measuring
device has to be filled separately (e.g. 2 x 0,50kg). During the filling process the
measuring material has to be slightly and constantly compressed in the measuring
chamber in order to provide enough place for 1,00kg of shavings. After finishing the
filling process, all of the measuring material has to be 5cm below the back case
edge.

List of calibration curves

Pressing the or key in the measuring for at least 3
seconds and a list with all available sorts will appear. Select

your sort by pressing

or and confirm it with the key.

The measurement will continue automatically.

• Woodchips: standard chips of wood (forest wood chips) according to EU-norm
CEN/TS 14961 class P16 and P45.

• Coarse WC: for coarse chips of wood P45 but with fewer fines. If the weight of
the filled 13 litre bucket is beyond 2,6 kg, the standard wood chips calibration
curves (2,4k resp. 2,0k) have to be used!

• Industr. WC: for industrial chips of wood without barks and fines (similar P63)
and fresh wood chips P16 & P45 (which are not older than two weeks after
cutting down the tree). If the weight of the filled 13 litre bucket is beyond 2,6 kg,
the standard wood chips calibration curves (2,4k resp. 2,0k) have to be used!

• P100 chips: very coarse chips of wood according to class P100. Information:

−

Mn

P100 chips are bigger than G100 chips of wood! To avoid filling differences in
cause of these coarse chips make more measurements with one sample and
note the average!

Information: There is the possibility to add further existing calibration curves (e.g.
shredder, logging debris wood chips) to your moisture meter.

Definition of wood chips classes

The stated numbers refer to the particle size that goes through round gaps of the
corresponding diameters (e.g. P16 - 16 mm).

o P16 minimum 80% of the bulk is between 3,15 and 16 mm
o P45 minimum 80% of the bulk is between 3,15 and 45 mm
o P63 minimum 80% of the bulk is between 3,15 and 63 mm
o P100 minimum 80% of the bulk is between 3,15 and 100 mm

4.0 CHANGING BATTERIES

Your new device is provided with batteries. Fitting and
changing of batteries:

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 batteries in the device. Make sure that
the positions of the battery poles are correct.

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. If you do not use your moisture meter
for a longer period, remove the batteries. For eventual
resulting damages we cannot provide any warranty.
