Table 1-1 6712FR Sampler Features (Continued)

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	Allows for sample sizes to be based on flow. (This option is available only with
Sample Volumes	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-	The suction head, is the vertical distance from the flow stream to the liquid detec-
tion Head	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	• Run Immediately: Starts the sampling program immediately.
Start Time Settings
	• 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-	Continuous Sampling: When sample bottles are regularly replaced, the sample
ning Program	distribution can restart with the first bottle set after the last bottle set is filled,
	without interrupting the running program.
