Brookfield R/S Coaxial Cylinder Rheometer - Manual (Page 57)

Brookfi eld Engineering Labs., Inc. Page 57 Manual No. M08-219-B1211
The data in the following table is for plate/plate systems and is valid for a measuring gap of 1
mm. For other plate distances, please calculate K
⋅γ
with the formula:
K γ = (2 π/60) * (R/H) R = radius, H = gap

A.2 Error Messages
The R/S+ Rheometer is user-friendly regarding errors. When errors occur, they are trapped, and the
user is informed on the LCD. The most frequent error messages are explained in this section.
Range Error
Cause: User’s error at input. The user has tried to input a value that is less than
the allowed minimum value or is more than the allowed maximum value.
