III.8 Running a Test
A viscosity test is started by pressing the Run button on the Configure Viscosity Test
screen. When Run is pressed, the display will change to the Running Viscosity Test screen
(see Figure III-9).

Data
Figure III-9
The Running Viscosity Test screen provides information on the current measurement
including: Torque, Viscosity, Shear Stress, Shear Rate, Temperature and Speed.
Torque
is the deflection of the Viscometer torque sensor. It is described as a percent
(%) and has a range of 0 – 100%. The DV2T 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.
TIP: Torque on the DV2T is equivalent to the dial reading from the Brookfield Dial
Reading Viscometer or the % reading from Brookfield Digital Viscometers
(DV-E, DV-I, DV-II, DV-III).
Viscosity
is calculated from the measured Torque based on the selected spindle and
speed of rotation. The units of viscosity are defined in the Global Settings section of
the Settings Menu
. If the Torque reading falls below 10%, the labels in the data
fields will flash to indicate an error condition.
Shear Stress
is calculated from the measured Torque based on the selected spindle.
The units of shear stress are defined in the Global Settings section of the Settings
Menu
. If the Torque reading falls below 10%, the labels in the data fields will flash
to indicate an error condition.
TIP: Shear Stress will be displayed as zero for spindles that do not have SRC
values.
