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 81.
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 600
Sonde meet certain conditions.
See Sampler Enable on page 84.
Pauses and Resumes Create intermittent sampling schedules.
See Pauses/Resumes on page 85.
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 storm-water run-off
sampling.
See One-Part and Two-Part Programs on page 23.
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 78.
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 78.
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 78.
Three Flexible
Start Time Settings
• Run Immediately : Starts the sampling program immediately.
• Delayed Start : Starts the sampling program after a user-definable delay of
1 to 999 minutes.
• Clock Time : Starts the sampling program at a user-definable time on one
or more days of the week.
See Start Times on page 86.
Option for a Continuous
Running Program
• Continuous Sampling : If the sample bottles can be properly serviced, 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 81.
