2.4.4 Load test

Test programs that are created (Configure Viscosity Test/Configure Yield Test) can be saved to the internal memory
of the DVNext or to a USB Flash Drive. These files can be re loaded into the DVNext for immediate use through the
Load Test function. A file that is placed onto a USB Flash Drive can be loaded onto any DVNext Rheometer.
Within the Load Test function, the user can access the internal memory of the rheometer or any USB Flash Drive that
is connected to a USB port .
is connected. The first USB Flash Drive that is connected will be referred to as #1 on both the Load Test screens and
the Status Bar. As many as three USB Flash Drives can be connected to the DVNext at any time.
Test files that are displayed on the screen can be sorted by date of creation or by alpha/numeric. This sorting is
selected by pressing the Navigation Icon
TIP: Manage Files function can be used to move Test files from internal memory to a USB Flash Drive.

The currently selected spindle. All Yield and Stress calculations will be made
based on the Spindle selection and the Immersion Mark. Spindle choice is
limited to vane spindles or user defined custom spindles.
Specify the immersion location of the AMETEK Brookfield vane spindle.
Primary is at the immersion mark shown on the spindle shaft. Secondary is at
the mid-point of the vane surface (see Section IV.5).
Specify a speed of rotation for Pre-Shear of the sample.
Pre-Shear
Specify the duration of the Pre-Shear step.
Specify the speed of rotation used to return the %Torque reading to zero
before starting the yield measurement.
Specify the duration of a rest period prior to starting the yield test.
Specify the speed of the yield test.
Specify the end point of the test. Normally set to 100%.
A live signal from the rheometer when a temperature probe is attached
(AMETEK Brookfield Part No. DVP-94Y). Also shown is the set point used to
control the attached temperature controller (AMETEK Brookfield Thermosel
or TC-XX0SD / TC-XX0AP Temperature Baths).
Define the limits for acceptable measurement data.
Create a message that the user will see when the test begins.
Define the memory location where the data will be saved.
The rheometer will point to the USB Flash Drive according to the order in which it
