Meaning of the results:
„FEUCHTE" (HU): moisture content in % of the sample weight.
„FESTSTOFF" (dM): dry matter (solids) in % of the sample weight
„ATRO" (AO): moisture relative to the solids, e.g. 50 % moisture and 50 % solids
mean 100 % ATRO, a German abbreviation used in the chipboard industry.
„PER 1000" (PM): g solids per 1000 g sample weight, e.g. 15 % solids mean 150
PM, a value which is used in German waste water plants.

) Automatic function (Konsta Stop) parameters:
"GAB" is the weight loss in mg, possible are 4; 8; 16; 32 mg. This parameter
depends mostly on the sample weight. For an accuracy of measurement of approx.
0,1 % this parameter has to be set correctly. E.g. a sample weight of approx. 4 – 8 g
needs a setting to 4 mg, because 4 mg is 0,1 % of 4 g.

"AIn" is the reading interval in seconds. This parameter depends on how fast (or
slow) the sample material will loose it's weight during the drying process. For
materials with a faster weight loss the parameter has to be set to small value (4 or 8
sec). Please make some tries to find out the best value for this parameter. The goal
should be, that the sample should dry as fast as possible, but it should dry also
completely.
"Abn" is the time delay after which the automatic function will start to ask the balance
for the weight loss. This parameter should be set to a higher value than 1 minute
(standard), if the sample has to be dried with very low temperature and therefore the
weight loss will start after a longer period than 1 minute.
