Distribution Methods Composite: Samples deposited in a single large bottle.
Sequential: Only one sample placed in each bottle.
Samples Per Bottle: Multiple samples placed in each bottle
Bottles Per Sample: One sample deposited in multiple bottles
Multiple Bottle Compositing: A combination of samples per bottle and
bottles per sample distribution methods.
Time Switched Bottles or Bottle sets: Control the sample distribution
using clock times.
See Distribution on page 84.
Programmable Sampler
Enable
A 6700 sampler can be programmed to enable or disable a running sampling
program when readings received from a connected rain gauge, module, or YSI
Sonde meet certain conditions.
See Sampler Enable on page 87.
Pauses and Resumes Create intermittent sampling schedules.
See Pauses/Resumes on page 89.
Two-Part Programming Two-part programming lets you set up a sampling program that divides the
bottles into two groups, filling each group according to separate pacing,
distribution, sampler enable, and pause and resume settings. Ideal for stormwater
run-off sampling.
See One-Part and Two-Part Programs on page 25.
Auto Suction Head or Fixed
Suction Head
The suction head, is the vertical distance from the flow stream to the liquid
detector. Extended programming has two settings.
Auto-Suction Head: The head is automatically determined.
Fixed Suction Head: A user-definable measurement for the head.
Note: See Suction Head on page 81.
Suction Line Rinses Program setting for the number of times (0 to 3) that the 6700 rinses the
suction line before drawing a sample.
See Rinses and Retries on page 82.
Sampling Retries Program setting for the number of times (0 to 3) that the 6700 attempts to
sample if it fails to deliver the entire sample volume.
See Rinses and Retries on page 82.
Three Flexible
Start Time Settings
Option for a Continuous
Running Program
Run Immediately: Starts the sampling program immediately.
Delayed Start: Starts the sampling program after a user-definable delay of
1to999minutes.
Clock Time: Starts the sampling program at a user-definable time on one
or more days of the week.
See Start Times on page 89.
Continuous Sampling: When sample bottles are regularly replaced, the
sample distribution can restart with the first bottle set after the last bottle
set is filled, without interrupting the running program.
See Distribution on page 84.
