Brookfield DV3T Rheometer - Manual (Page 39)

Brookfield Engineering Labs., Inc. Page 39 Manual No. M13-2100
Temperature is the input value from a connected Brookfield temperature probe. The DV3T is
provided with a DVP-94Y probe that can be inserted into the test sample or a water bath. The
Cone/Plate version of the DV3T can be utilized with a sample cup that includes an embedded
temperature probe. Some Brookfield accessories include temperature probes (Thermosel) or
optional chambers with embedded temperature probes (Small Sample Adapter). The units of
temperature are defined in the Global Settings section of the Settings Menu
.
The temperature display will be ---- when no temperature probe is connected.
Speed is the selected speed from the Configure Viscosity Test screen.
TIP: Speed can be changed by switching from the Running Viscosity Test screen to the
View Test screen using the command key at the bottom of the screen.
TIP: When Speed is changed in the View Test screen, the Test Name will be changed to
unsaved.
The status of the test configuration is indicated in the grey bar above the data fields. A configuration
that has been saved will be indicated by a display of the test file name. A configuration that is not
saved will be indicated by a display of Unsaved Test.
The Real Time Graph is displayed at the bottom of the Running Viscosity Test screen. This graph
shows all measurements during the life of the test. The Y-axis can represent any data field. The
data field represented on the graph is shown by the blue dot; for example, in Figure III-14, Torque
is shown on the graph. Any data field can be selected by touching the screen.
The Real Time Graph will indicate data points collected as part of the test with a blue dot on the
data line. At the conclusion of the test, the Real Time Graph is displayed for review. Once the OK
button is pressed, only the data points collected as part of the test will be available for review/save.
The Real Time Graph cannot be seen again once the Results page is in view.
QC Limits will be indicated on the Real Time Graph when the selection for Y-Axis is the same as
the selection for QC Limits (see Section III.9).
Two Command Keys are available on the Running Viscosity Test screen: Stop Test and View Test.
Stop Test: Immediately stops the current test. The user will be presented with a confirmation
box. The test will continue to run until Yes is selected in the Confirmation box.
If any data had been collected during the test, the user will be presented with the
Results screen (see Section III.11). If data was not collected, the user will be
returned to the Configure Viscosity Test screen.
TIP: If the operator selects “Do not show this message again” within the
Confirmation box, then the Confirmation box will no longer be displayed when
Stop Test is pressed. This condition can be reset in the Display section of User
Settings
.
View Test: Change the view from measurement to test parameters including: Spindle, Speed,
Temperature, End Condition, Data Collection, QC Limits, Instructions, and Density.
The View Test screen includes a live display of Torque and a Time parameter that
shows the total elapsed time for the test (see Figure III-15).
