For every step, there are the following inputs:
Input Step Nr 1
Start[1/s]: 0010.00
End[1/s]: 0100.00
Nr of MP: 01
0
Start Value
End Value
Number of MP (measur. points)
(input of numbers: see Chapter 6.4)
Minimum- and maximum-values of start values and end values depend on selected measuring system
for shear rate (D[s-1]) and shear stress (Tau[Pa]). At input the Rheometer checks start and end values
(if these values lie within due range) and indicates error massage “Range-Error” if out of range:
Range-Error
Range-Error
Start-Value:
min: 0.90
max: 1032.80
Name of Value out of range
Allowed mimum-value
Allowed maximum-value
This message will be indicated, for example, at input of the start value D[s
-1
] with measuring system
CC25, which lies outside the range of 0.9 ... 1032.8 s
-1
.
However, in the case, start value, end value and number of measurement points were input correctly,
the request for input of step duration will be indicated:
Input Step Nr. 1
time [s]: 0060
Step duration
Number of currently editing step
Minimum step duration:
D [s-1] tmin = number of measurement points * 4 s
n [rpm] tmin = number of measurement points * 4 s
Tau [Pa] tmin = number of measurement points * 1 s
M [‰] tmin = number of measurement points * 1 s
Maximum step duration allowed is: 3600 s
The duration value is automatically checked for the correct range (dependent on number of meas.
points). At wrong input, the “Range-Error” message will be indicated, accompanied by allowed values.
Attention: The more time between two measuring points, the higher precision of determination
of physical parameters!
This procedure of input Start-, End-Value, Number of MP, time is repeated for each step.
Finally the Program must be named and saved:
