12. Weigh the dried soil sample, sample ring, and drying pan.
NOTE: Ensure that the soil sample has cooled to room temperature to prevent inaccurate weight readings. Soil
samples should be kept in a desiccant chamber while cooling.
13. Subtract the tare weight of the drying pan.
14. Record the dry soil weight for evaluation in LABROS SoilView-Analysis software.
15. Document and enter the weight of the soil sample ring for evaluation in the
information tab of LABROS SoilView-Analysis software.
If no weight values have been recorded during the measurement (e.g., a VARIOS Standalone
Configuration), and the water content is not needed, the sample does not have to be dried in
the oven. In this case, the performance of postprocessing steps are not required.
2.7.7.1 EVALUATION
The LABROS SoilView software generates
*.varios
files. These files can be opened using the
LABROS SoilView-Analysis software.
The LABROS SoilView-Analysis software performs the following operations for
VARIOS measurements:
• Specify all required parameters for the evaluation of the sample, such as geometric and
device parameters, tare weights, etc.
• Visualize the raw data such as thermal conductivity values and weight changes.
• Recalculate thermal conductivity values and net weight data in relation to the volumetric
water content calculation.
• Calculate and visualize the data for the thermal conductivity characteristic.
• Fit state-of-the-art thermal functions to the data, visualization of the functions, and listing
of the values and confidence limits of the conductivity parameters.
• Export graphs, raw data, calculated data, fitted functions, and other parameters of interest.
The software leads the user through the VARIOS evaluation process using the tabs shown in
