2.2 KEY FACTORS TO GET RELIABLE MEASUREMENTS
Getting reliable results from VARIOS measurements is dependent upon the following factors.
• Air gaps in the sample may form if the needle moves around in the sample.
If an air gap forms, the accuracy of the measurement will be affected. The sensor needle
needs to fit tightly in the sample to reduce the chance of the needle moving around.
• Small stones or pebbles in the sample may prevent the sensor needle from being inserted
into the sample.
Try installing the sensor through the second drilling hole.
2.3 CONNECT VARIOS CONFIGURATIONS
The VARIOS can be configured two ways depending on the type of measurement data
required and the accessories available. This section describes the two configurations and
how to connect the accessories.
2.3.1 VARIOS THERMAL DRYOUT CONFIGURATION
The VARIOS Thermal dryout configuration uses both the VARIOS and a HYPROP Balance to
calculate the thermal conductivity as a function of water content of soil samples or various
suitable materials. Both the VARIOS Complete Set and the Extension Set can be used for the
Thermal dryout configuration.
