With the following calculation the right TK1 can be calculated:
For example: Measure with your BM2 at 23°C a moisture content of 30%
and by the sample in the fridge (at app. 8°C) just 20%.
NOTE: Before measuring allow your BM2 to become conditioned to
the sample temperature.
2.9 Measuring range
In the menu item “Valid” is the validity of the calibration curve given. A
valid measurement is shown in the measuring window black, a invalid is
sown gray. This feature can be best explained by an example.
The goal is a valid range from 5% up to 25% moisture content because
for certain materials readings above 25% lose accuracy
Enter the following values in the shown order:
idx idx idx idx idx idx
(1) (2) (3) (4) (5) (6)
Idx(1) Idx(2) Idx(3) Idx(4) Idx(5) Idx(6)
50% 25.1% 25% 5% 4.9% 0%
0 0 1 1 0 0
The measruing range should e defined in the area of the measured
samples.
2.10 Completion
If all values of the created calibration curve are stored in the BM2
device, you can measure the material with the new calibration curve.
