occur in the middle of a pulse countdown and the first sample
will be deposited in the new bottle or set when the countdown is
completed. (Display #271)
The Nonuniform Time option specifies the method by which non-
uniform intervals are to be entered in the extended program
sequence (Display #s 26 or 27). If you select "clock-time," you will
be able to enter a specific time and date for each sample event
when entering settings in the program sequence. If you select
"MINUTES," you will be able to enter nonuniform intervals in
minutes. Nonuniform times are not available in a STORM sam-
pling routine. (Display #280)
The Calibrate Sampler option adds or removes the calibration
settings to the program sequence. If you select "ENABLE," the
calibration displays will be added to the program sequence and
you will be able to precisely calibrate the sample volumes.

The Sampling Stop/Resume configure option lets you add stop
and resume settings (Display #s 100, 101, and 102) to the
program sequence.
The Stop/Resume settings appear in the key time section of the
program sequence. (You can enter as many as 24 times: 12 stop
times and 12 resume times.) For example, the Stop/Resume
option allows you to define a sampling routine, which will take
samples at intervals of 15 minutes between 6 a.m. to 8 a.m. and
between 4 p.m. to 6 p.m.. Sampling Stops and Resumes are not
available in a storm routine.
If you are using a time-switched sampling routine that includes
the use of stops and resumes, the sampler will reset the
time-switch interval at each resume time. If a routine with
time-switches every hour is programmed for stop and resume
times, the first time-switch would occur an hour after the resume
time.
Switches would repeat every hour until a stop time occurred or
the routine was completed. See Example Sampling with Stops
and Resumes.
Enable/Disable – Select "ENABLE" to add the stops and
resume settings to the program sequence. (Display #300)
Sample at Stop – The Sample at Stop setting directs the
sampler to take a sample at stop times. (Display #301)
Sample at Resume – The Sample at Resume setting directs the
sampler to take a sample at resume times. (Display #302)
The Start Time Delay option sets the amount of time in minutes,
between the time you press the start sampling key and the time
the sampling routine is initiated. The sampler's response varies
according to specific entries: 0, 1, and entries greater than 1.
