6712FR Refrigerated Sampler

Section 1 Introduction

Table 1-1 6712FR Sampler Features (Continued)

Command Driven Operation

• Operate sampler functions using RS-232 communications.

 

 

 

Warning Messages

• Pump Tube Warning. The 6712FR displays a warning to inspect the tube.

 

 

• Internal Battery Warning. From the Maintenance screen, the 6712FR displays a

 

warning when it is time to replace the internal battery. The internal battery

 

preserves stored data when the 6712FR is without external power.

 

 

Optional Dialout Modem

The 6712 controller can be ordered with a factory-installed 2400 baud dialout

 

modem. With the modem you can:

 

• connect to the sampler and download data using Flowlink software.

 

• program the sampler to call a contact list when an “alarm” condition exists.

 

• use the Remote Commands to control the sampler’s operation from a remote

 

location.

 

 

On-Line Help Notes

When programming the sampler, press the [?] (Help) key for a brief help note. All

 

help topics appear in the index.

 

 

Two Programming Levels

Standard programming lets you set up typical sampling programs quickly.

 

Extended programming includes all features available in standard programming

 

plus additional features.

 

 

 

Sample Delivery System Features

 

 

Peristaltic Pump

Benefits: Liquid moves continuously under pumped flow. The pump has no

 

 

metering chambers or gravity fed internal tubing to trap sediment or residual

 

liquid. Sample liquid contacts only the strainer, suction line, tube coupling,

 

pump tube, bulkhead fitting, and sample bottles.

 

 

LD90 Liquid Detector

Non wetted Detection: Sample liquid never touches the detector.

 

 

 

Two Line Purges in Sampling

The sampling cycle always includes a pre-sample purge and post-sample purge

Cycle

that clears the suction line of residual liquid.

 

 

Easy Grab Samples

Simply disconnect the pump tube from the bulkhead fitting on the center section,

 

and place the pump tube over your sample container.

 

 

Vinyl and PTFE

3/8-inch ID (Inside Diameter) vinyl line.

Suction Lines

3/8-inch ID PTFE lined with polyethylene jacket.

 

 

 

Standard Programming Features

 

 

Pacing

Uniform Time Pacing: Sampling at regular time intervals.

 

 

Flow Pacing: Sampling at regular flow-volume intervals.

 

 

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.

 

 

Three Flexible

Start 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.
