Explanations for the ATRO units
The ATRO unit is required exclusively in the wood industry.
In practice, wood contains different amounts of water, which can
change continuously. The water content affects the combustion
performance of the wood and the heat value. The water evaporates
during drying. When wood is stored in the open air, it reaches the so-
called air-dried status (A.D.) of 15% to 20% water content. The
moisture is completely removed from the wood by heating the wood
to temperatures over 100°C. This condition is called absolutely dry
(abs.dry).
The wood moisture (ATRO) is the amount of water contained in the
wood, expressed in terms of the percentage of the mass of the water-
free wood and is calculated from the difference between the fresh
weight (MW) and the dry weight (DW).
5.4.5 Print rate
The interval at which interim results are printed is set at "PRINT
RATE". The print interval can be set in 0.1 min increments from 0.1 -
10.0 min.
