Brookfield DV3T Rheometer - Manual (Page 23)

Brookfield Engineering Labs., Inc. Page 23 Manual No. M13-2100
II.7 Out of Range
The DV3T Rheometer will give on screen indications when the measurement is out of range of
the instrument. When the %Torque reading exceeds 100% (over range), the display of %Torque,
Viscosity, and Shear Stress will be EEEE (see Figure II-7). If the %Torque value is between 0 -
9.9%, the data field label will flash. When the %Torque is below zero (negative values), the display
of Viscosity and Shear Stress will be ----.
TIP: Brookfield recommends collecting data only when the %Torque reading is between
10 - 100%.
Figure II-7
Measurement data should not be collected when the %Torque reading is out of range. The out of
range condition can be resolved by either changing the speed (reduce speed when reading is out of
range: high) or changing the spindle (increase the spindle size when the reading is out of range: low).
TIP: When comparing data, the test method is critical. Be sure that you know the proper spindle
and speed required for the test method. If readings are out of range, this condition should
be reported as the test result.
