to run the VARIOS. Using this method, the Balance automatically records the weight loss of the
sample. Therefore the thermal conductivity can be related to the respective water content of
the sample.
NOTE: The HYPROP Balance has a weight limit of 2,200 g. Under normal conditions, the provided sample ring will not
exceed this limitation.
2.7.1.2 VARIOS WITHOUT BALANCE (VARIOS STANDALONE)
To measure the thermal conductivity of various materials, the sample can be placed directly
on the VARIOS. Then connect the VARIOS to a computer via a METER USB adapter and USB
cable (
). Thermal conductivity data is recorded and evaluated using the LABROS
SoilView and LABROS SoilView-Analysis software, respectively. This method does not
compare the thermal conductivity as it relates to water content.
2.7.2 CONNECTING DEVICES TO A PC COMPUTER
Connect the devices to a PC as described in
. All connected devices should be
automatically detected by the LABROS SoilView software and displayed in the device tree
on the left side of the user interface main window (
). If a device is not listed in the
device tree after it has been plugged in, search manually by clicking on Show Devices. If
a connected device is not found after manually searching, please refer to
for
troubleshooting advice or contact
