ISCO 6700SR - Start Times; Start Time Diagram for Sampler Enable

6700SR Refrigerated Sampler

A sampler running a pause/resume program resets the pacing in-
terval at each resume time. You can program the sampler to take a
sample at resume times. (See screen 24.)
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 con-
trolled by your selections from the start time screens. (The start
time screens appear in
Figures 24

During the delay, the sampler
ignores disable signals from a
flow logger, flow meter, a 700
series module, rain gauge, or
I/O pin.
Sampler Enabled
at Start Time
A sample event at the Start Time always occurs
for all time-paced programs except random. For
flow-paced programs, it occurs when the program
requires a sample at the Start Time.
A sample event at the Enable Time always occurs
for event-paced programs. For other programs, it
occurs at the Enable Time only when the program
requires a sample at enable.
