The extended time pacing options are uniform time and non- uniform time. “Uniform time” pacing is identical to “time” pacing in standard programming. Nonuniform time pacing uses an irregular interval between sample events; each interval is indi- vidually programmable. There are three types of nonuniform time pacing:

•Nonuniform clock time pacing.

•Nonuniform interval pacing.

•Random interval pacing.

For clock time pacing, enter specific times for each sample event (see screen 2). You can enter as many as 99 clock times, but the interval between times cannot be greater than 24 hours. (Remember to use a 24-hour clock when entering times.) The sampler takes a sample at the start time.

For nonuniform interval pacing, enter the number of sample events spaced at intervals of minutes: 12 samples at 5 minute intervals, 6 samples at 10 minute intervals, and so on. The sampler accepts as many as 99 nonuniform interval entries. The sampler takes a sample at start time.

To program the sampler for random interval pacing, enter the length of time you want to sample. The run time is the only random programming setting you’ll need to enter because the sampler derives the number of sample events required for the program from the distribution settings. (You can combine random pacing with any distribution.) Each time you run the program, the sampler generates a new set of random intervals. This makes each sample event unpredictable from run to run.

In both nonuniform clock time pacing and nonuniform interval pacing, the sampler takes a sample at the start time. For random pacing, however, it takes the first sample at the end of the first interval, not at the start time.
