Value That Can Be Varied
The last adjusted set point TS is always saved when the rheometer is turned off. When the
rheometer is re-started, the Peltier will return to the last set point.
Modify the set point temperature with the and keys.
The temporary flashing of three points “• • •” confirms the acceptance of the new set tem-

VI.5.2 MAIN Menu → Single Measurement
This function measures shear stress or shear rate (CSS or CSR) at constant user defined
values. The user may select a choice of measurement method from the follwoing:
Shear Rate D [s-1]
Speed n [U/min] or [rpm]
Shear Stress Tau [Pa}
Torque M[ ‰ ] [1000 ‰ correspond to 50 mNm]
Before you can start the measurement itself, you have to input the following values:
• Selection of the measuring system used (see Section VI.3: Selecting from Lists).
• Selection of test method (see Section VI.3: Selecting from Lists). This is where you de-
cide if you want a controlled rate measurement (shear rate, RPM) or a controlled stress
measurement (shear stress, torque).
• Input of pre-set values (see Section VI.4: Input of Numerical Values and Alphanumer-
ic Texts ).
- D [s -1 ] range of values depends on the measuring system
- n [rpm] 0.7 to 1,000 rpm
- Tau [Pa] range of values depends on the measuring system
- M[‰] 0-999 ‰
• Input of desired number of measuring points (see Section VI.4: Input of Numerical
