Section 1 Introduction

Option for a Continuous Run-
ning Program
• 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.
Extended Programming Features
Pacing
• Uniform Time Pacing: Sampling at regular time intervals.
• Nonuniform Time Pacing: Sampling at irregular time intervals.
• Random Interval Pacing: Sampling at unique random time intervals generated
by the controller.
• Flow Pacing: Sampling at regular flow-volume intervals.
• Event Pacing: Sampling each time a user-definable event occurs.
Flow Proportional
Sample Volumes Allows for sample sizes to be based on flow. (This option is available only with
uniform time pacing.)
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.
Programmable Sampler Enable A 6712FR sampler can be programmed to enable or disable a running sampling
program when readings received from a connected rain gauge, module, or
SDI-12 Sonde meet certain conditions.
Pauses and Resumes Create intermittent sampling schedules.
Two-Part Programming Two-part programming lets you set up a sampling program that divides the bot-
tles into two groups, filling each group according to separate pacing, distribution,
sampler enable, and pause and resume settings. This is ideal for storm-water
run-off sampling.
Auto Suction Head or Fixed Suc-
tion Head The suction head, is the vertical distance from the flow stream to the liquid detec-
tor. Extended programming has two settings.
• Auto-Suction Head: The head is automatically determined.
• Fixed Suction Head: A user-definable measurement for the head.
Suction Line Rinses Program setting for the number of times (0 to 3) that the 6712 rinses the suction
line before drawing a sample.
Sampling Retries Program setting for the number of times (0 to 3) that the 6712 attempts to sample
if it fails to deliver the entire sample volume.
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.
Option for a Continuous Run-
ning Program 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.
