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

This function measures shear stress or shear rate (CSS or CSR) at constant user dened

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

‰] [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).
