6700 SAMPLERS
The effects of resetting the interval can be seen in this example:
A sampler has been programmed to sample every 15 minutes and
to reset the interval when enabled. It receives an enable signal at
10:03 and takes a sample. After resetting the interval, the sampler
takes subsequent samples at 10:18 (not 10:15), 10:33 (not
10:30), and so on.
Screen 21 is available only when you select NO at screen 20. You
can have the sampler continue the countdown, repeating it as
often as necessary while the sampler is disabled, or you may suspend
the countdown while disabled, resuming the countdown as
the sampler is enabled. The standard program allows the countdown
to continue while disabled.

PAUSES/RESUMES
Pause and resume settings, available in extended programming,
create an intermittent sampling schedule. A program with
pauses and resumes begins sampling at its programmed start
time,continuinguntilthefirstpausetimeanddayoftheweek.It
then suspends sampling until the first resume time, when it
begins sampling again. If the start time falls within a pause
period, the sampler will not begin sampling until the next
resume time. Pause and resumes repeat weekly.
You can enter up to nine pairs of pause and resume times using
screen 22. The pause and resume times shown as examples in
this screen suspend the program between 5:00 p.m. Monday and
8:00 a.m. on Tuesday and between 5:00 p.m. Tuesday and 8:00
a.m. on Wednesday. If the start time is Monday at 8:00 a.m., the
sampler takes samples between 8:00 a.m. and 5:00 p.m. Monday;
between 8:00 a.m. and 5:00 p.m. Tuesday; and, continues after
8:00 a.m. Wednesday. To remove pause and resume settings from
a program, select CLEAR in screen 22.
A sampler running a pause/resume program resets the pacing
interval at each resume time. You can program the sampler to
take a sample at resume times. (See screen 23.)
START TIMES
It is important to understand the difference between the time at
which you run a program and the program’s start time. Running
a program simply means selecting RUN from the sampler’s start
up menu. The start time is the time at which the sampler begins
the program’s first sample interval countdown. The start time is
controlled by your selections from the start time screens. (The
start time screens appear in Figure 27 and Figure 29 Standard
andExtendedProgrammingStartTimes.)
Each program contains start-time settings that tell the sampler
when to begin the program. When programming the sampler, you
can select one of three start time options: NO DELAY TO START,
DELAYED START, or CLOCK TIME.
