The Counting Time/Sample displayed is entered as the Counting Time described in Counting
Time Section 4. However, this time is the elapsed time from the start of the count cycle
instead of live time as in the other Data Calculation programs. The prompts for Single Photon
are described below. Repeat counts and replicates are not used in the Single Photon Program.
Number of Data Points
This feature allows you to enter the number of data points you want to record and print over
the sample counting time. The number of data points is limited to the number of count
updates that can take place and be printed in the Counting Time/Sample and no more than
one point every 0.05 mm (20 points/minute).
Count Time/Sample = Count Time/Point x Points/Sample
For rapidly decaying samples, you may select many data points over a short period of time.
For slower decaying samples, select fewer data points over a longer period of time. Refer to
Count Time per Data Point for selecting the length of time to accumulate counts for each data
point.
To change this setting, highlight “Number of Data Points”, and enter the number of data
points.
