then rerunning the test (see Section III.8). This method can allow you
to quickly evaluate the spindle selection to determine the best speeds
for testing.
# of Points
: The test will complete when the specified number of data points has been
collected. Data is collected according to the Data Collection setting (see
Section III.5). The range of data points is: 1 – 9,999.
# of Revolutions
: The test will complete when the specified number of revolutions of the
spindle has occurred. Data is collected according to the Data Collection
setting (see Section III.5). The range for number of revolutions is:
1 – 9,999.
Torque
: The test will complete when the specified Torque value is measured. Data
is collected according to the Data Collection setting (see Section III.5). The
range of values for the measured Torque is: -10.0 – 100.0.
Viscosity
: The test will complete when the specified Viscosity value is measured. Data
is collected according to the Data Collection setting (see Section III.5). The
range of measured Viscosity is 0 – 10,000,000,000 cP.
Note: The Viscosity End Condition should be selected in consideration of
the Range provided by the spindle and speed selected. Check the Range
value by selecting Spindle in Configure Viscosity Test. If you choose a
Viscosity End Condition greater than the Range of the spindle and speed
settings, then the value shown in the End Condition field will be EEEE. In
this case, the end condition will never be achieved.
Temperature
: The test will complete when the specified Temperature value is measured
to within the indicated Tolerance. The Tolerance specifies how close the
measured temperature should be to the specified temperature value to
consider the target reached. Temperature is measured through the use
of a connected Brookfield temperature probe (DVP-94Y, CPA-44ZPY
cup, SC4-XXRPY chamber). Data is collected according to the Data
Collection setting (see Section III.5).
Temperature: -100 – 300°C
Tolerance: 0.0 – 9.9°C
TIP: A small tolerance value will require a much longer time to reach
the End Condition.
TIP: If using PG Flash to create a test program, consider using a
larger Tolerance value for the End Condition and then use a
second step for thermal equilibrium (End Condition Time). This
two step method can reduce the variability in test time caused
by variations in temperature sensors.
III.7 Additional Test Parameters
The Configure Viscosity Test screen includes a More/Less Bar. When pressed, the More
Bar will present several additional Test Parameters including: QC Limits, Instructions,
Reports, and Density. These parameters are always available and active regardless of
the position of the More / Less Bar.
