Brookfield DV3T Rheometer - Manual (Page 82)

Brookfield Engineering Labs., Inc. Page 82 Manual No. M13-2100
Yield Test parameters are shown in a single area within PG Flash without a Program Grid (only
a single step for Yield Tests). All yield parameters are available including Spindle Settings, Test
Settings and Test Instructions & Path Settings.
Spindle: 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.
Immersion Mark: Specify the immersion location of the Brookfield vane spindle. Primary is at
the immersion mark shown on the spindle shaft. Secondary is at the mid-point
of the vane surface.
Pre-Shear Speed: Specify a sped of rotation for pre-shear of the sample
Pre-Shear Time: Specify the duration of the Pre-Shear step.
Zero Speed: Specify the speed of rotation used to return the %Torque reading to zero before
starting the yield measurement.
Wait Time: Specify the duration of a rest period prior to starting the yield test.
Test Run Speed: Specify the speed of the yield test.
Torque Reduction: Specify the end point of the test. Normally set to 100%.
Temperature Set Point: A live signal from the rheometer when a temperature probe is attached (Brookfield
Part No. DVP-94Y). Also shown is the set point used to control the attached
temperature controller (Brookfield Thermosel or TC-XX0SD / TC-XX0AP
Temperature Baths).
Yield Low Limit: Parameter based on the chosen QC Limits.
Yield High Limit: Parameter based on the chosen QC Limits.
Save Results Path: Define the memory location where the data will be saved.
Instructions: Create a message that the user will see when the test begins.
