There should be ample distance between the sample material and the cover when
closing the cover. (Diagram 2).
Note:
Double-check that only the sample material is displayed as a load. The sampling tray
must be tared.
Press the key to start up the humidity determination process.
The set parameters can be seen on the display screen.
The drying process is started by pressing the key again. This process can be
aborted at any time by pressing the key.
The drying process duration depends on the set mode.
Mode 1-3 checks any alteration in the weighing result (details ”mode“ chapter)
Mode 4-7 is time-dependent (details function type “mode“ chapter)
9.3.1 Test accuracy
The size of the sample has a great influence on the accuracy of the test procedure.
A larger sample provides a more exact test result. However, the drying procedure
duration increases with the size of the sample.
The test result can be adulterated to a great degree if the test samples are too small
(light). If samples are used that dry out very quickly, it should be ensured that the
drying parameters (temperature, time interval) are set in an appropriate fashion.
It is very important to apply the test material evenly to the sampling tray (see diagram
1 chapter 9.3).
If you wish to ensure that the time interval between two data transfers has been se-
lected correctly, it is necessary to carry out an additional test using longer time inter-
vals. In the event that a significant divergence is determined when comparing both
humidity values, the time interval should be extended.
