Brookfield R/S Coaxial Cylinder Rheometer - Manual (Page 41)

Brookfi eld Engineering Labs., Inc. Page 41 Manual No. M08-219-B1211
The following inputs have to be made for each step:
Input Step Nr1
Start[1/s]:0010.00
End[1/s]: 0100.00
Nr of MP: 010
End Value
Start Value
Number of
Measurement Points
(data points)
Minimum and maximum start and end values depend on the selected measuring system for shear
rate (D[s
-1 ]) and shear stress (Tau [Pa]). At input, the rheometer checks the start and end values
and indicates the message “Range error” if out of range:
Range error
Start value:
Min: 0.90
Max: 1032.80
Allowed minimum
value
Name of value out of
range
Allowed maximum
value
For example, a range error message would be displayed if a start value for D[s -1 ] is not within the
range of 0.0 - 1032.8 s -1 when using measuring system CC25.
If the start value, end value and number of measuring points are acceptable, the user will be
prompted for Step Duration:
Input Step Nr. 1
Time[s]: 0060
Number of steps
being edited
Step duration
Minimum step duration:
Available Measurement Types User Defi ned Range
Shear Rate D{s -1 ] tmin = number of measuring points * 4 s
Speed n[rpm] tmin = number of measuring points * 4 s
Shear Stress Tau [Pa] tmin = number of measuring points * 1 s
Torque M[ ‰ ] tmin = number of measuring points * 1 s
Maximum step duration: 3600 s
The instrument will automatically check the input. If there is a range error, “Range error” would
be displayed together with the allowable range.
The more time between two measuring points, the higher the accuracy
of the determined physical parameters!
