Example: Collect All with Delay
Figure 27 shows an example in which the delay is 0.2 min and the fraction size is
1 min. The diverter valve remains at divert during the delay time. The chart recorder
makes the first tick mark (following the start/run mark) at 1.0 min, and each
subsequent tick mark at 1 min intervals. The drophead advances at 1.2 min and
continues advancing at 1 min intervals. Each fraction size is still 1 min.
Fig. 27. Example showing Collect All with a delay of 0.2 minutes.
Figure 28 shows an example of a Collect All experiment in Drop mode with a 2-drop
delay and a 10-drop fraction size. In this case the chart recorder makes its first tick
mark (following the start/run mark) at 8 drops:
(fraction size – delay = 10 drops – 2 drops = 8 drops)
