Two (2) graphs are displayed in Figure II-7:

1. % Torque vs. Time

This graph displays the % Torque values versus the time (since the beginning of the Run

cycle) at which the data points were collected. Torque is displayed in units of % of full

scale range while the Time is displayed in seconds.

2. Stress vs. Apparent Strain

This graph displays the calculated Stress values versus the calculated Apparent Strain values

for each data point collected. Stress is displayed in units of Pascals (Pa) while Apparent

strain is displayed in units of radians (rad).

See Appendix D - Calculations - for more information regarding these calculated values.

Double-clicking on either graph enlarges or zooms that graph and displays it on the left side

while shrinking the other graph and displaying it on the right.

The three (3) toolbars on the right side of the page can be resized and moved within the confines

of the toolbar box by clicking and dragging the toolbar sizer located to the left of the toolbar title.

II.7 Options Toolbar

Note: Many of the Options buttons are two (2) state buttons. Two (2) state buttons have

two (2) positions: depressed and unpressed. A visually depressed button indicates

the option is turned ON while a visually unpressed button indicates that the option

is OFF. Clicking a two (2) state button causes its state to change, thereby turning

an option ON and OFF.

The following is a functional description of each of the buttons on the Options toolbar of the

Graphs page:

Replot

Click this button to refresh both graphs. Any time another option

is changed, the Replot must be clicked to see those changes.

On-Line Plotting This is a two (2) state button. Turning this option ON causes data

to be plotted on both graphs during the run cycle of a yield test.

Keep in mind that the YR-1 Rheometer must be communicating

with the host PC and EZ-Yield

TM

in order for this data to be plotted.

Show Data Values This is a two (2) state button. Turning this option ON causes a hint

box to be displayed whenever the mouse cursor is placed on the

Stress versus Apparent Strain graph within the data boundaries of

the graph. This hint box displays the Time, % Torque, and Stress

of the position pointed to by the cursor for the % Torque vs. Time

graph. It displays Stress and Apparent Strain of the position pointed

to by the cursor for the Stress vs. Strain graph.

Calibration Data

This is a two (2) state button. Turning this option ON causes the

straight line, representing the calibration information of the rhe-

ometer, to be displayed along with the user data on the % Torque

vs. Time graph.
