6712SR Refrigerated Sampler Section 5 Extended Programming The 6712SR Sampler has two sets of programming screens. The first set, called standard programming screens, lets you set up typical sampling programs easily and efficiently. The second set, extended programming screens, lets you create sophisticated programs for complex sampling applications. All of the sampling features available with standard programming screens, discussed in Section 4, are available with extended programming screens.
6712SR Refrigerated Sampler Section 5 Extended Programming Each part has its own group of bottles. Because settings for each part are independent of each other, the sampler, when running a two-part program, fills each bottle group as if they were being filled by two different programs. Two-part programs finish when both parts are done. Two-part programming is ideal for sampling storm events.
6712SR Refrigerated Sampler Section 5 Extended Programming The current program is the program you see when you select PROGRAM from the main menu and page through the programming screens. It is the program the sampler uses when you select RUN from the main menu. You cannot delete programs, but you can modify them as often as necessary. To run a program with different settings without losing the settings in your current program, select a stored program and modify its settings.

6712SR Refrigerated Sampler Section 5 Extended Programming 5.9.3 Nonuniform Time Pacing The extended time pacing options are uniform time and nonuniform time. “Uniform time” pacing is identical to “time” pacing in standard programming. Nonuniform time pacing uses an irregular interval between sample events; each interval is individually programmable. There are three types of nonuniform time pacing: • Nonuniform clock time pacing. • Nonuniform interval pacing. • Random interval pacing. 5.9.
6712SR Refrigerated Sampler Section 5 Extended Programming 5.10 Distribution Distribution describes how the sampler is to deposit samples. A sample is the volume of liquid deposited in a bottle. A sample event includes the full sampling cycle and may deposit a sample into more than one bottle. You can program the sampler for five distribution methods: • Sequential • Bottles per sample • Samples per bottle • Composite • Multiple Bottle Compositing 5.10.

6712SR Refrigerated Sampler Section 5 Extended Programming 5.11 Flow Proportional Sample Volumes The 6712 can collect flow proportional sample volumes. For some sampling protocols, these flow-weighted, variable-volume samples can be more representative of the stream. This is because stream characteristics often change as the flow fluctuates. Variable-volume sampling is possible when the sampler is programmed for Uniform Time pacing.
6712SR Refrigerated Sampler Section 5 Extended Programming 5.11.1 Calculating Variable Sample Volume Settings The entry for the SAMPLE VOLUME display can be calculated based on expected flow rates and collection volume requirements. The number of pulses or flow module volume that you enter should ensure that the minimum volume of liquid required for analysis is collected without exceeding the bottle volume capacity of the sampler.

6712SR Refrigerated Sampler Section 5 Extended Programming These factors would be applied to the following equation. (Greatest Total Flow Vol) / (Flow Pulse Vol) 10 ml for every __ pulses = (Total Bottle Vol) / (10 ml per unit) From the scenario we can apply the factors to the equation. (666,667 gallons / 100 gallons) 10 ml for every 7.0 pulses = (9,400 ml / 10 ml) At high flow rates, a number below 7 would overfill the bottle. At low flow rates, a number greater than 16 would collect too little sample.
6712SR Refrigerated Sampler Section 5 Extended Programming When the sampler detects that it is disabled at start time, it suspends the program until it is enabled. Once enabled, the sampler collects a sample only when programmed to take a sample at the enable time. The diagram in Figure 5-4 shows the sampler’s response when enabled or disabled at the start time. Sampler enabled at start time A sample event at the start time always occurs for time-paced programs (except for random).
6712SR Refrigerated Sampler Section 5 Extended Programming 5.12.1 Sampler Enable This example uses a sampler with an attached 730 Bubbler Flow Module, Rain Gauge and an SDI-12 sonde at address 5 with four parameters.

6712SR Refrigerated Sampler Section 5 Extended Programming 5.13 Sampler Enable Responses In addition to programming enable conditions, extended programming lets you control the sampler’s response to its enable state. You can: • Stay enabled after the first enable. • Set up a repeatable enable. • Take a sample at enable or disable. • Delay the start of sampling after the enable. • Reset the sampling interval countdown each time the sampler is enabled.
6712SR Refrigerated Sampler Section 5 Extended Programming 5.13.4 Delay To Start Of Sampling If you have selected ONCE ENABLED STAY ENABLED and have chosen to not sample at the enable, you have the opportunity to suspend the start of sampling. This choice is useful for storm programs that require a flow-paced sample taken after the initial grab sample.

A program with pauses and resumes begins sampling at its programmed start time, continuing until the first pause time and day of the week.
6712SR Refrigerated Sampler Section 5 Extended Programming Adjust Suction Head – If you have chosen to manually enter the suction head, and are in the manual paused state, the scrolling menu will have an option to adjust the suction head. If you make changes to the suction head value, the sampler logs a changed suction head event. 5.16 Sampling Reports The 6712 records a variety of data while running a sampling program. Sample reports can be found in Section 4.
6712SR Refrigerated Sampler Section 5 Extended Programming 5.18.2 Programming Style The sampler has two different styles of programming screens: normal and quick view. These are both explained in Section 3. When you are in extended programming, the default style is Quick View, which allows you to move more quickly through the screens. If you prefer a step-by-step display for the screens, switch to the Normal setting. 5.18.
6712SR Refrigerated Sampler Section 5 Extended Programming Bottle Full Detect BOTTLE FULL DETECT? YES NO Bottle Full Detection – The sampler can detect a full bottle condition when collecting samples in a single bottle (composite sampling). When the sampler detects a full bottle, it stops the sampling routine. A BOTTLE FULL condition will also stop a sampling routine that is set to RUN CONTINUOUSLY. The Bottle Full Detect screen allows you to enable or disable this feature.
6712SR Refrigerated Sampler Section 5 Extended Programming • 3-second pulse at the beginning of forward pumping only, marking the time the sampler deposited the sample. • Variable duration pulse generated during the pump cycle, from the beginning of the pre-sample purge to the end of the postsample purge. • Variable duration pulse generated only during forward pumping.

6712SR Refrigerated Sampler Appendix C General Safety Procedures The safety of the personnel who use the 671SR is a critical consideration. The following procedures, applicable to working in and around manholes and sewers, are those used by Black & Veatch, a respected consulting firm, and are published here by their permission. Field personnel must keep safety uppermost in their minds at all times. When working above ground, rules of common sense and safety prevail.
6712SR Refrigerated Sampler Appendix C General Safety Procedures C.1.4 Falling Objects Items placed near the manhole opening may fall and injure a worker in the manhole. All loose items should be kept away from the manhole opening. This applies to hand tools as well as stones, gravel and other objects. C.1.5 Sharp Edges Sharp edges of items in or near a manhole may cause cuts or bruises. C.1.
6712SR Refrigerated Sampler Appendix C General Safety Procedures A person should never enter a manhole unless he is wearing personal safety equipment, including a safety harness and a hard hat. Two persons should be stationed at the surface continuously while anyone is working inside a manhole, to lift him out if he is overcome or injured. One man cannot lift an unconscious man out of a manhole.

6712SR Refrigerated Sampler Appendix C General Safety Procedures does not support life. The word has sometimes been misinterpreted as meaning suffocation, which is only one kind of asphyxiation. “In nearly all cases of death in sewers, the real killer is hydrogen sulfide. It is important that this fact be recognized. Many cities diligently test for explosive gases, which is very important, and they may measure the oxygen concentration which usually is unimportant, but they rarely measure H2S.
6712SR Refrigerated Sampler Appendix C General Safety Procedures “Be very careful to avoid high H2S concentrations, flammable atmospheres, and hazards of physical injuries. Remember that much H2S may be released by the stirring up of sludge in the bottom of a structure. Obey your senses in respect to irritating gases, such as chlorine (unconsciousness comes suddenly from breathing too much). Be cautious about strange odors. Do not determine percent oxygen in the air.
