The user is informed that there are five (5) math models which can be used on the buffer data. A
model is selected by pressing the appropriate numeric key. No matter the model selected, the
following screen will be displayed for the duration of the mathematical analysis:
Figure 59
When the calculations are complete, the results for the particular model will be displayed as follows:
Figure 60
This screen, for the Standard CASSON Model, is typical for all five (5) of the math models. Note
the cP in the upper right-hand corner to remind the user that the values are cP based. It could have
been SI (if the user had opted for SI display in the SETUP menu) as shown on the next two (2) of
the following four (4) math model screens:
The user may elect to print test results in order to obtain hard copy results. This is accomplished
by pressing the PRINT key while any of the above screens are being displayed causing the following
to be printed:
 STANDARD CASSON PRINTOUT
Sample Name: ________________________________________________
Operator Name: ___________________________
Date: 01/14/1999 Time: 02:27 Math Model Results: CASSON (STANDARD)
Model: HB Spindle: 34

The equation for each model is described below with a definition of parameters. Please contact
Brookfield or an authorized representative if further information is required.
Note: The confidence of fit parameter used in all of the models is an indication of how well
the model fits the data set. 100% indicates the best fit.
