Save Path
Define the memory location (internal or USB Flash Drive) where the Test Results will be saved.
TIP: Selecting a data path can help to organize data storage in the internal memory of the
DV3T. By preselecting the data path, operators are directed to put the data from specific
tests into specific areas.
TIP: If you select a data path that includes a USB Flash Drive location and the Flash Drive
has been removed, an error message will be displayed.
IV.6 Running a Yield Test
A Yield Test is started by pressing the Run button on the Configure Yield Test screen. When Run
is pressed, the display will change to the Running Yield Test screen (see Figure IV-7).

Measurement Data
Figure IV-7
The Running Yield Test screen provides information on the current measurement including: Delta
Torque, Torque, Stress, Strain, Temperature, and Speed.
Delta Torque is the difference between the current %Torque value and the previous %Torque
value. As the sample approaches its yield point, the Delta Torque percentage should decrease.
If the Torque Reduction for the test is 100%, the yield point occurs when the % decrease in
Torque = 100.
Torque is the deflection of the Rheometer torque sensor. It is described as percent (%) and has
a range of 0 – 100%. The DV3T will provide measurement results within the stated accuracy
provided the Torque reading is between 10 and 100%. If the torque reading falls below 10% the
labels in the data fields will flash to indicate an error condition. Brookfield does not recommend
that data be collected below 10% Torque however data collection is not restricted.
