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.
