Two Sigma Percent Terminator
Mark this box to activate count termination from statistical accuracy. Two options
are available:
Any region
Enter the level of statistical accuracy for each region (as a percent value) that you
would like to achieve before counting terminates. Counting terminates when the
sigma value of any one region is reached. Using this feature, counting may
terminate before the specified count time elapses.
All regions
Enter the level of statistical accuracy for each region (as a percent value) that you
would like to achieve before counting terminates. Counting terminates when the
sigma value for each region is reached. Using this feature, counting may
terminate before the specified count time elapses.
Changes to this parameter for an active assay will be implemented immediately.
Low CPM Threshold
Mark the check box to activate low CPM count termination. You can enter CPM
values for each counting region to have counting terminate if these values are not
reached. The sample count terminates if any one of the regions does not meet
the specified minimum CPM threshold within the first 30 seconds of counting.
