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 Collect Single
Point at Step End. During the test, the total time required to reach 200 cP is 10
minutes 40 seconds. Total points collected will be 11 with the last data point taken
at 10 minutes 40 seconds, an average of the last 20 seconds of the step.
No Data
: End Condition is met and no data is collected.
