CAL
Press the „
change“
button, after a few seconds the value of
the calibration weight appears in the display.
Place the calibration weight on the middle of the scale pan.
Display disappears.
After a few seconds appears --- 200,000 g
7. Getting correct measuring values
7.1. Very important is a good preparation of the sample material. It should be
homogeneous and no bigger parts should be there. Parts of more than 5 mm
diameter can stay wet in the middle and incorrect values are the results.
7.2. Different material should be crushed or rasped and liquids should be well stirred.
7.3. Use a cold drying pan for every new measurement. A cold sample on a hot pan
will cause a weight loss even before the start of the measurement.
7.4. We recommend a sample weight of at least 4 g. The greater the sample weight,
the better reproducible your measurement will be.
7.5 Try to find out the best drying temperature to reach short measuring times and
good results.
7.6 It is recommended to have some reference values by using the standard method
with drying cabinet and separate balance.
7.7. For drying liquids or sticky materials we recommend to use aluminium foils as
sample trays to keep the stainless steel pans free from sample remains. See list of
accessories.
8. Cleaning and maintenance
8.1 Please transport the instruments very careful. The built-in balance is very
sensitive against shocks.
8.2 Clean the heater and the surfaces of the instrument only with a wet duster. Plug
out the mains cable before cleaning the radiator.
8.3 Any maintenance should only be done by authorized persons.
