4.6 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 main
menu. The start time is the time at which the sampler begins the
program’s first sample interval countdown. The start time is con-
trolled by your selections from the start time screens.
Each program contains start-time settings that tell the sampler
when to begin the program. When programming the sampler, you
can select one of four start time options: NO DELAY TO START,
DELAYED START, CLOCK TIME or WAIT FOR PHONE CALL.
• Select NO DELAY TO START when you want the
sampler to start as soon as you select RUN.
• Select DELAYED START when you want the sampler to
delay from 1 to 999 minutes before starting the
program.
• Select CLOCK TIME when you want the sampler to
begin the program at a specific time on at least one day
of the week.
• Select WAIT FOR PHONE CALL when you want the
sampler to begin the program after receiving a remote
command to start.
4.6.1 How Do Start Times
Work?
As soon as you select RUN from the main menu, the sampler
checks the program’s start time settings. With a “DELAYED
START” setting, the sampler starts a countdown to the start
time. The period between the time you select RUN and the start
time you’ve specified in the program is called the “delay to start
time.”
When you run a program with “CLOCK TIME” settings, the
sampler also starts a countdown to start time until the day of
week and clock times are met.
The sampler may not collect a sample at the start time. The
sampler must be enabled, and the pacing selected must call for a
sample at start. In any event, the sampler checks the pacing set-
tings and begins the pacing-interval countdown.
