OUT OF RANGE INDICATORS
The DV-III Ultra is capable of measuring instrument torque within the range of 0 to 100%. Based
on this measurement, viscosity and shear stress are calculated. Brookfield recommends that data be
collected only in the range of 10 to 100%. Any data collected outside of this range is considered
invalid.
The DV-III Ultra provides the following display indicators when the measurement point is outside
of the 10-100% acceptable range.
S
TORqUE GREATER THAN 100%
When Rheometer torque exceeds 100%, the parameter display field will show “EEEE” for torque,
viscosity and shear stress.

S
TORqUE LESS THAN 10%
When Rheometer torque drops below ten (10) percent, the Rheometer will continue to display
measurement (%, cP, D/cm

) values with units flashing:
