11. Number of Samples Known Alternatively if the total number of samples to be collected over the total sampling period is known the flow increment between samples can be deter mined by calculating how much total flow will occur during the sampling period and dividing this by the total number of samples to be collected For example assume that the average flow is 1 75 MGD that the composite sampling period is 2 days and that it is desired to collect 100 individual samples The flow increment between samples is calculated 1 75 MGD 1 750 000 GAL DAY 1 750 000 GAL DAY X 2 DAYS 3 500 000 GAL 3 500 000 GAL 100 SAMPLES 35 000 GAL SAMPLE Thus the desired flow increment between samples is approxi mately 35 000 gallons E 1 3710 Portable Samplers Appendix E Calculating Flow Increment Between Samples E 2 Calculation of Number of Flow Pulses Once the desired flow increment between samples is known the number of flow pulses to be programmed into the sampler may be calculated assuming that the volume of the flow pulses from the flow meter is known The number of flow pulses is calculated by dividing the flow increment between samples by the volume of each flow pulse Using the first example above the flow increment between samples was calculated as 52 000 gallons assume that each flow pulse represents 10 000 gallons of flow The number of flow pulses to be programmed into the sampler is calculated 52 000 GAL 10 000 G

32. If your sample volumes vary significantly with the entered values check the suction line first Be sure the line slopes continuously downhill and is draining completely after each pumping cycle Then check the suction line entries in the configure sequence to see that they are accurate The calibration procedure is intended to be for fine tuning only After you enter the sample volume actually delivered as shown in step 8 all subsequent sample volumes delivered will be adjusted to correct for the difference between the expected sample volume and the actual volume entered Clear the adjustment by changing a suction line entry in the Suction Line configure option or by re initializing the sampler When calibrating the sampler best results are obtained when the unit is installed on site If you cannot calibrate on site be sure the calibration head matches the actual head If the sampling will occur at a head of 10 feet calibrate the sample volume at a head of 10 feet Because the sample volume can be calibrated to 10 ml a graduated cylinder should be used to facilitate mea surement A graduated cylinder is available from the factory Refer to Appendix B at the back of this manual for details The calibration pump cycle will include rinse cycles and retries if the sampler is configured to perform them see Section 3 9 6 This ensures that the calibration procedure includes the pump cycle used while running the sampling program E
33. In the extended programming mode the Sample Pacing section Sample Pacing allows you to select flow pacing or one of two types of time pacing uniform or nonuniform If you select uniform time intervals the settings for time intervals are identical to the time intervals entered in the basic programming mode Nonuniform times allow you to pace the sampler at irregular intervals Before you enter nonuniform time intervals you must specify either minutes or clock times in the Nonuniform Times configure option You can enter nonuniform intervals in two ways The first method allows you to define the interval between each sample event in minutes For example you can program the sampler to take sample 2 after an interval of 10 minutes sample 3 after an interval of 30 minutes sample 4 after an interval of 60 minutes and so on Sample 1 would be taken at the start time The second method allows you to enter a specific time and date for each sample event For example with non uniform time pacing samples can be collected at specific times and dates at irregular intervals 6 00 a m on April 15 noon on April 15 7 00 a m on April 16 and 1 00 p m or 13 00 in military time on April 16 If you have several sequences of nonuniform times you can use the program storage feature to save the pro grams using each sequence When you enter nonuniform times you will be prompted to enter the number of nonuniform samples TAKE SAMPLES

51. n M 1 Appendix E Calculating Flow Increment Between Samples The 3710 Sampler will accept flow proportional inputs from an external flow meter or flow logger These electronic flow input signals are transmitted to the sampler at fixed increments of total flow for example every 10 000 gallons Each time 10 000 gallons of liquid flows past the flow meter it sends a signal to the sampler which registers it as a single flow pulse You can program the sampler to totalize any number of flow pulses from 1 to 9 999 before initiating a sampling event For example if the sampler were programmed to totalize 5 flow pulses and each flow pulse represented 10 000 gallons of total flow a sample would be collected each time 50 000 gallons 5 flow pulses of 10 000 gallons each had passed the flow meter Time Interval Known If the desired average time interval between individual samples is known the flow increment between samples can be determined by calculating how much flow based on the average flow rate occurs during that time interval For example assume that the average flow is 2 5 MGD and it is desired to collect a sample every 30 minutes The flow increment between samples is calculated 2 5 MGD 2 500 000 GAL DAY 2 500 000 GAL DAY X 1 DAY 24 HR X 1 HR 60 MIN 1736 GAL MIN 736 GAL MIN X 30 MIN SAMPLE 52 080 GAL SAMPLE Thus the desired flow increment between samples is approxi mately 52 000 gallons

If a problem is encountered while running a sampling routine which has resulted in missed samples an asterisk will appear in the lower right corner of the display as illustrated below EM There are two instances where the sampler will enter the run state after the START SAMPLING key is pressed but will not begin the sampling program If the sampler is acting as a slave in a master slave configuration the sampler will not begin the program until it receives an enable signal transmitted by the master sampler If the sampler is interfaced with a Liquid Level Actuator or other equipment capable of transmitting an inhibit signal the sampler will not begin the program until the inhibit signal is suspended The sampler will use one of the following displays to inform you of these conditions Table 3 7 Run State Displays Composite Sampling Indicates the sample number of the next sample and the total number of samples for time paced routines The current time is shown in the lower right corner Indicates the sample number of the next sample and the total number of samples for flow paced routines Indicates the sample number of the next sample The question marks indicate the sampler will use the float shut off to terminate the routine The second line reports the scheduled time of the upcoming sample event and the current time Indicates the sample number of the next sample The q

221. you read this section The most effective way to learn how to program the 3710 Sampler is to read this section get a sampler and experiment A few minutes in the office or laboratory spent in actually pro gramming the sampler and observing its operation usually proves to be a worthwhile investment of time If you are already familiar with the sampling capabilities of the 3710 Sampler you may prefer to begin with Section 3 5 This section introduces the specifics of programming the sampler This information serves to acquaint you with the 3710 Sampler s operation It introduces you to the types of sampling performed by the sampler and the terminology used to describe those capa bilities A sample event is the process of taking a sample It includes the full sampling cycle Although the cycle varies according to the program settings which define the sampling routine the cycle described here follows the typical sequence This information is presented here to provide you with a frame of reference for the remainder of this section 1 Asample event is initiated when the interval since the pre vious sample has expired For time based intervals the samples are taken when the internal clock reaches the scheduled time of the sampling event For flow paced inter vals the interval is set to the programmed number of pulses received from a flow meter the sample event begins when the pulses are counted down to zero 2 The pump rotates in the
