Multi Point
: Collect multiple data points based on time. The Data Interval is specified in
Hours:Mins:Secs. If the End Condition is set to Time, then the total number
of points will be calculated and displayed in the Data Collection screen. If
the End Condition is not based on time then it is possible that the step will
conclude prior to a data point being collected. If you want a data point at
the conclusion of the step regardless of the time interval, you can check the
check box in the Data Interval screen.
Example 2:
End Condition is Time = 2 minutes, Multi Point Data Interval is 10 seconds.
Total points collected will be 12 with the last data point taken in the last
second of the step.
Example 3:
End Condition is set to Viscosity = 200 cP, Multi Point Data Interval is 10
seconds. During the test the total time required to reach 200 cP is 65
seconds. Total points collected will be 6 with the last data point taken at
60 seconds, 5 seconds before the test is finished.
Example 4:
End Condition is set to Viscosity = 200 cP, Multi Point Data Interval is 10
seconds. Check the check box to Also Collect Single Point at Step End.
During the test, the total time required to reach 200 cP is 65 seconds. Total
points collected will be 7 with the last data point taken at 65 seconds, 5
seconds after point #6 taken at 60 seconds.
Multi Point Averaging
: Specify an amount of time over which to average measured
data. Collect multiple data points based on time until the End
Condition is met. Each data point is an averaged value. If the
Averaging Duration is shorter than the Data Interval for the
step, then the average will be performed for the specified time
at the end of the Data Interval. The total number of points to be
collected will be displayed if the End Condition is set to Time. If
the End Condition is not based on time, then it is possible that
the step will conclude prior to a data point being collected. If
you want a data point at the conclusion of the step regardless
of the time interval, you can check the check box in the Data
Interval screen.
Example 5: End Condition is Time = 2 minutes, Multi Point Data Interval is 10 seconds.
Averaging Duration is 5 seconds. Total points collected will be 12 with the
last data point taken in the last second of the step. Each data point will be
an average of the data measured in the last 5 seconds of each Data Interval.
Example 6: End Condition is set to Viscosity = 200 cP, Multi Point Data Interval is 10
seconds. Averaging Duration is 5 seconds. During the test, the total time
required to reach 200 cP is 63 seconds. Total points collected will be 6
with the last data point taken at 60 seconds, 3 seconds before the test is
finished. Each data point will be an average of the data measured in the
last 5 seconds of each Data Interval.
Example 7: End Condition is set to Viscosity = 200 cP, Multi Point Data Interval is 10
seconds. Averaging Duration is 5 seconds. Check the check box to Also
Collect Single Point at Step End. During the test, the total time required to
reach 200 cP is 65 seconds. Total points collected will be 7 with the last
data point taken at 65 seconds, an average of the 5 seconds after point #6.
Example 8: End Condition is set to Viscosity = 200 cP, Multi Point Data Interval is 1
minute. Averaging Duration is 20 seconds. Check the check box to Also
