1.1 DESCRIPTION

The 6000UPG Environmental Monitoring System is a multiparam eter, w ater quality measurement, and data logging system . It is intended for use in research, assessment, and regulatory com pliance applications.

Measurement parameters include:

• Dissolved Oxygen

• Conductiv ity

• Specific Conductance

• Salinity

• Total Dissolv ed S olids

• Resistivity

• Tem perature

• pH

• ORP

• Depth

• Level

• Am monium/Ammonia

• Nitrate

• Turbidity

The 6000

UPG is ideal for profiling and monitoring w ater conditions in lak es, riv ers, w etlands,

estuaries, coastal waters, and monitoring wells. It can be left unattended for week s at a tim e with measurement parameters sampled at a user-defined setup interval and data securely saved in the unit's internal memory. The 6000 water, or in as little as a few inches of water. The fast sensor response of the 6000

UPG can be used 500 feet (152 meters) below the surface of the

UPG and its

built-in data logging make it ideal for vertical profiling. Its small size means it can fit dow n 4 inch (10.2 cm) diameter monitoring wells.

A patented Rapid Pulse Dissolved Oxygen Sensor exhibits low stirring dependence and, therefore provides accurate results without an expensive and bulky stirrer. Because stirring is not required, battery life is extended. In addition, because of the nature of the technology, sensor drift caused by passive fouling is minimiz ed.

The Model 6000

UPG is designed to house 4 field-replaceable probes (6 sensors) and the option to

add a depth sensor module to the sonde body. If necessary, the dissolved oxygen-conductivitytemperature, pH, amm onium, nitrate ORP, and turbidity sensors are quickly replaced in the field.

The 6000 program. Every 6000

UPG communicates with an A SC I I terminal or a computer with a terminal emulation

UPG comes with IBM-compatible PC-based software for sim ple and conv enient

setup and data handling. Reports and plots are automatically generated and their presentation easily customized. Data is easily exported to any spreadsheet prog ram for more sophisticated data processing.

1-1

The RS-232C and SDI-12 interfaces provide maximu m v ersatility for system networking and real time data collection. Several 6000 valuable water quality data at a variety of depths. For real time results, the 6000

UPG units are easily installed in a vertical string prov iding

UPG can interface to

radio telemetry system s and satellite, telephone, or cellular phone data collection platforms. In addition, the unit can be used with our 610-D or 610-DM display /logger for profiling or spot sampling applications. The 6000

UPG is equipped with sensor and communication circuitry to

eliminate ground loop interference.

When the 6000

UPG is factory configured for internal power, it operates using eig ht C-size alkaline

batteries. These batteries are easily replaced in the field, without disassembly of the unit. The minimal power requirements of the Rapid Pulse Dissolv ed Oxy g en Sensor combined with state-of-the-art electronic circuits and software can prov ide up to 90 day s of battery life during normal use, depending on the activated sensor configuration.

The 6000

UPG comes standard with 256 kilobytes of memory; this is enough to store 150,000

individual parameter readings for a typical deploy ment.

Optional cables are available for interfacing the 6000

UPG with a computer, terminal, or

display/logger. These cables are waterproof at the sonde connection and can be used in the lab or field.

See Appendix D for a complete list of accessories and calibration reagents.

3. BASIC OPERATION

In the previous Section, you learned how to install probes and set up the PC6000, Ecowatch for Windows, and 6000 Model 6000 6000

UPG with a 610-series display/logg er, refer to the operations manual for the 610 to obtain

UPG and how to view your data on a computer display. I f y ou choose to use y our

similar instructions to those provided below.

3.1 GETTING READY TO CALIBRATE

WARNING: Reagents used to calibrate and check this instrument may be haz ardous to y our health.

Refer to Appendix A for health and safety information.

Before you begin the calibration procedures outlined below, you m ay find it helpful to follow some or all of these calibration tips.

1. You will need one or more containers to hold calibration standards. YSI prov ides a calibration

cup, but a standard 800 mL beaker also works well.

UPG sonde software. In this section, you will learn how to calibrate and run the

2. If you use the 6000

UPG Transport Cup for dissolved oxygen calibration, mak e certain to loosen

the seal to allow pressure equilibration before DO calibration (water-saturated air calibration).

3. For maximum accuracy, the use of a small amount of previously -used calibration solutions to

prerinse the sonde is suggested. You may wish to sav e old calibration standards for this purpose.

4. Fill a large bucket with ambient temperature water for rinsing the sonde between calibration

solutions.

5. Have several clean, absorbent paper towels or cotton cloths available to dry the sonde between

rinses and calibration solutions. It is important to remov e as much residual liquid as possible from the sonde after each rinse. Shake the sonde to remove excess rinse water from the inside of the guard. Then dry the outside of the sonde and probe guard. Drying the sonde and probes in this way reduces carry-over contam ination of calibrator solutions and increases the accuracy of the calibration, particularly when using lower conductivity calibration standards.

6. It is not necessary to remov e the probe g uard to rinse and dry the probes between calibration

solutions. The inaccuracy resulting from simp ly rinsing the probe compartment and drying the outside of the sonde is minimal.

3-1

3.2 CALIBRATION PROCEDURES

WARNING: Calibration reagents may be hazardous to your health. Refer to Appendix A for

health and safety information.

A calibration cup is supplied with the Model 6000

UPG. Because the calibration cup fits over the

outside of the sonde probe guard, it is not recommended or necessary to rem o v e the probe g uard to calibrate the sensors. Follow the procedures below to calibrate the sensors. Temperature does not require calibration and is, therefore, not included in the Calibrate menu. ORP calibration is required only infrequently and is discussed in Section 4.2. For more detailed calibration procedures, which can be used to enhance the accuracy of some measurements, see Section 4.2.

The following sequence is provided as an EXAMPLE of the process the user will utilize to calibrate all sensors. Although conductivity was chosen for this general example, more detailed

instructions for the calibration of the conductivity sensor are found in the next section.

From the sonde Main menu select 2. Calibrate.

The number in parentheses is the default value of this parameter and will be used in the calibration if only Enter is pressed without typing in another value. Remember that this entry should reflect the actual value of your solution and that entry of values other than the default m ay be necessary. Similar prompts will be display ed for calibration of all param eters.

After the calibration value is input (or the default accepted) and Enter is pressed, a real-time display similar to that shown above will appear on the screen. N ote that all parameters which have been enabled will appear, not just the one being calibrated at the moment. You should carefully observe the stabilization of the readings of the parameter w hich is being calibrated and, w hen the readings are stable for approximately 30 seconds, press Enter to accept the calibration. The acceptance will be acknowledged and calibration of the chosen sensor is complete. Then, as instructed, Hit any key to return to the Calibrate menu.

NOTE: If an ERROR message appears, begin the calibration procedure again. Be certain that the value you enter for the calibration standard is correct. Also see Section 8, Troubleshooting for more information on error messag es. If error messages continue to be observed during calibration, contact YSI Customer Service (see Appendix C for contact inform ation).

CAUTION: With rare exception, be certain to immerse the entire array of sensors in solution standards for calibration of all parameters. Most calibrations require readings not only from the sensor being calibrated but also from the temperature sensor. Tem perature compensation is an important criterion in nearly all of the calibration procedures. In addition to temperature, the conductivity reading of the standard is required in several calibration routines and the reference electrode of the pH probe must be in the same solution as the nitrate and ammonium sensors for proper function.

Specific start-up calibration procedures for all sensors which commonly require calibration are provided in the following paragraphs of this section. Remember that these are basic protocols designed to get the user up and running with regard to the 6000

UPG. The more-detailed discussion

of sensor calibration found in Section 4.2 should be examined prior to use of the instrument in the field.

NOTE: If the particular sensor listed is not installed in your sonde, proceed to the next sensor until the calibration protocol is complete.

IMPORTANT MESSAGE!

WHAT IF THERE IS NO RESPONSE TO A KEYSTROKE?

To save power, the 6000UPG will power down automatically if no interaction from the keyboard occurs for approximately 30 seconds. When the software is in this “sleep” mode, the first subsequent keystroke simply “wak es it up” and has no visible effect on the display. The next keystroke after the unit is “awakened” w ill be input to the softw are in the intended m anner. Thus, if you press a key after the 6000UPG has been inactive for some time and nothing seems to happen, press the key again.

CONDUCTIVITY

NOTE: This procedure calibrates not only conductivity, but also specific conductance, salinity,

and total dissolved solids.

Place approximately 500 mL of conductiv ity standard in a clean and dry calibration cup.

The conductivity standard you choose should be within the same conductiv ity rang e as the water you are preparing to sample. However, we do not recommend using standards less than 1 mS/cm. For example:

❏ For fresh water choose a 1 mS/cm conductivity standard. ❏ For brackish water choose a 10 mS/cm conductiv ity standard. ❏ For sea water choose a 50 mS/cm conductivity standard.

Caution: Before proceeding insure that the sensor is as dry as possible. Ideally, rinse the conductivity sensor with a small am ount of standard that can be discarded. Be certain that y ou avoid cross contamination of standard solutions with other solutions. Make certain that there are no salt deposits around the oxygen and pH/ORP probes, particularly if you are em ploy ing standards of low conductivity.

Without removing the probe guard, carefully immerse the probe end of the sonde into the solution. Gently rotate and/or move the sonde up and down to rem ov e any bubbles from the conductivity cell. The probe must be completely im mersed past its vent hole.

Allow at least one minute for temperature equilibration before proceeding .

From the Calibrate menu, select 1. Conductivity to access the Conductivity calibration procedure and then 1. SpCond to access the specific conductance calibration procedure. Enter the calibration value of the standard you are using (mS/cm at 25 C) and press Enter. The current values of all enabled sensors will appear on the screen and will change with time as they stabiliz e.

3-4

Observe the readings under Specific Conductance or Conductivity and when they show no significant change for approximately 30 seconds, press Enter. The screen will indicate that the calibration has been accepted and prompt you to Hit any key to return to the Calibrate menu.

Rinse the sonde in tap or purified water and dry the sonde.

DISSOLVED OXYGEN

Place approximately 1/8 inch (3 mm ) of w ater or a wet spong e in the bottom of the Calibration Cup or Transport Cup. Place the probe end of the sonde into the cup. Make certain that the DO and the temperature probes are not immersed in the water. Wait approximately 10 minutes for the air in the calibration cup to become water saturated and for the temperatures of the thermistor and the oxy g en probe to equilibrate.

CAUTION: If the Transport Cup is used, make certain that the cup is vented to the atmosphere by loosening the vent screw.

From the Calibrate menu, select 2. DO% to access the D O % calibration procedure.

Enter the current barometric pressure in mm of Hg . (Inches of Hg x 25.4 = mm Hg ).

NOTE: Remember that barometer readings which appear in meteorological reports are generally corrected to sea level and are not useful for your calibration procedure unless they are uncorrected.

Press Enter and the computer will indicate that the calibration procedure is in progress.

Calibration will AUTOMATICALLY occur after warmup interval. Warming Sensors: 27

After approximately 1 minute, the calibration will be complete. Press any key, as instructed, and the screen will display the percent saturation value which corresponds to your local barometric pressure input. For example, if your barometer reads 742 m m Hg, the screen will display 97.6 % (742/760) at this point.

After the calibration is complete, press any key to return to the Calibrate menu.

NOTE: Calibration of dissolved oxygen in the DO % procedure also results in calibration of the DO mg/L mode and vice v ersa.

Rinse the sonde in water and dry the sonde.

3-5

DEPTH

Following the DO calibration, leave the sonde in water-saturated air. Make certain that the sonde is not submerged in water for the depth calibration.

From the Calibrate menu, select 3. Depth to access the depth calibration procedure. Input 0.00 or some known sensor offset in feet (the depth sensor is about 0.46 feet above the bottom of the probe compartment). Press Enter and monitor the stabilization of the depth reading s w ith tim e. When no significant change occurs for approximately 30 seconds, press Enter to confirm the calibration and zero the sensor with regard to current barometric pressure. Then, as instructed, Hit any key to return to the Calibrate menu.

pH 2-POINT

Place approximately 400 mL of pH 7 buffer in a clean calibration cup. Carefully immerse the probe end of the sonde into the solution.

Allow at least 1 minute for temperature equilibration before proceeding .

From the Calibrate menu, select 6. pH to access the pH calibration choices and then 2. 2-Point. Press Enter and input the value of the buffer (or accept the default) at the prompt. Press Enter and the current values of all enabled sensors will appear on the screen and will change with tim e as they stabilize in the solution. Observe the readings under pH and when they show no significant change for approximately 30 seconds, press Enter. The display will indicate that the calibration is accepted.

After the pH 7 calibration is complete, Hit any key, as instructed on the screen, to continue.

Rinse the sonde in water and dry the sonde before proceeding to next step.

Place approximately 400 mL of a second pH buffer solution in a clean calibration cup. The second buffer might be pH 4 if the sample is expected to be acidic or pH 10 if the sam ple is expected to be basic. Carefully imm erse the probe end of the sonde into the solution.

Allow at least 1 minute for temperature equilibration before proceeding . Press Enter and input the value of the second buffer at the prompt. Press Enter and the current

values of all enabled sensors will appear on the screen and will change with tim e as they stabiliz e in the solution. Observe the readings under pH and when they show no significant chang e for approximately 30 seconds, press Enter. After the second value calibration is complete, Hit any key, as instructed on the screen, to return to the Calibrate m enu.

Rinse the sonde in water and dry the sonde.

Thoroughly rinse and dry the calibration cups for future use.

3-6

AMMONIUM (NH

) and NITRATE (NO

) 3-POINT

WARNING: AMMONIUM AND NITRATE SENSORS CAN ONLY BE USED AT DEPTHS

OF LESS THAN 50 FEET (15 METERS). USE OF T HE SENSORS AT GREAT ER DEPT HS IS LIKELY TO PERMANENTLY DAMAGE THE SENSOR MEMBRANE.

NOTE: The calibration procedures for ammonium and nitrate are sim ilar to pH except for the reagents in the calibration solutions. Suggested values for calibrants are 1 and 100 m g /L of either ammonium-nitrogen (NH

-N) or nitrate-nitrogen (NO3-N).

NOTE: The following procedure requires one 500 mL portion of 100 mg/L calibrant and two

500

mL portions of 1 mg/L calibrant. The 100 m g /l solution and one of the 1 mg/L solutions should be at ambient temperature. The other 1 mg /L solution should be chilled to less than 10 C° prior to beginning the procedure.

CAUTION: Proper calibration of the ammonium and nitrate sensors requires that the pH, conductivity, and temperature probes also be im mersed in the same solution as the sensor being calibrated. Therefore, do not remove the probe guard and attem pt to immerse individual sensors in different vessels. For the ammonium and nitrate sensors to function at all, there must be solution contact between the pH and the ammonium or nitrate probe.

Place 500 mL of 100 mg/L standard into a clean calibration cup. Carefully immerse the probe end of the sonde into the solution.

Allow at least 1 minute for temperature equilibration before proceeding .

Select 7. Ammonium or 8. Nitrate to access the appropriate calibration choices. Then select

the default. Press Enter and the current values of all enabled sensors will appear on the screen and will change with time as they stabiliz e in the solution. O bserv e the readings under NH4+ or NO3- . When they show no significant change for approximately 30 seconds, press Enter.

After the second value calibration is complete, as instructed, Hit any key to continue.

Rinse the sonde in water and dry the sonde prior to the next step.

Place 500 mL of the ambient temp erature 1 m g /L standard solution in a clean calibration cup. Carefully immerse the probe end of the sonde into the solution.

Allow at least 1 minute for temperature equilibration before proceeding . Press Enter and input the concentration value of the standard as requested or accept the default.

Press Enter and the current values of all enabled sensors will appear on the screen and will change with time as they stabilize in the solution. Observ e the readings under NH4+ or NO3- and w hen they have show no significant change for approxim ately 30 seconds, press Enter.

After the second value calibration is complete, as instructed, Hit any key to continue.

3-7

Place 500 mL of the chilled 1 mg/L standard solution in a clean calibration cup. Carefully immerse the probe end of the sonde into the solution.

Allow at least 5 minutes for temperature equilibration before proceeding. Press Enter and input the concentration value of the standard as requested or accept the default. Press Enter and the current values of all enabled sensors will appear on the screen and will change with tim e as they stabiliz e in the solution. Observe the readings under NH4+ or NO3- and when they show no sig nificant chang e for approximately 30 seconds, press Enter.

After the third value calibration is complete, Hit any key to return to the Calibrate menu.

Thoroughly rinse and dry the calibration cups for future use.

CALIBRATION TIP: AVOIDING DRIFT DURING CALIBRATION OF THE NH4+ AND NO3- PROBES AFTER pH CALIBRATION. Exposure to the high ionic content of pH buffers can cause a significant, but temporary, drift in either the ammonium or the nitrate probe. Therefore, when calibrating the nitrate or ammonium sensor, we recommend that you use one of the following methods to minimize errors in the subsequent readings:

❏ Calibrate pH first, immersing all of the probes in the pH buffers. After calibrating pH, place

the probes in 100 mg/L nitrate or ammonium standard and monitor the reading. Usually, the reading starts low and may take as long as 30 minutes to reach a stable value. When it does, proceed with the calibration.

❏ When calibrating pH, remove the probe guard and immerse only the pH and temperature

probes in the buffers. You can then calibrate nitrate or ammonium immediately after pH calibration.

TURBIDITY 2-POINT

WARNING: THE TURBIDITY SENSOR CAN ONLY BE USED AT DEPTHS OF LESS THAN

200 FEET (61 METERS). USE OF THE PROBE AT GREATER DEPTHS IS LIKELY TO PERMANENTLY DAMAGE THE SENSOR.

Select 9. Turbidity from the Calibrate Menu and then 2. 2-Point. NOTE: One standard must be 0 NTU, and this standard must be calibrated first.

To begin the calibration immerse the sonde in approximately 300 mL of 0 NTU standard (clear deionized, distilled, or tap water), as instructed, and press Enter. Input the value 0.00 NTU at the prompt, and press Enter. After calibration of the mechanical wiper speed, the screen will display real-time readings wh ich will allow y ou to determine when the turbidity values have stabiliz ed. If the readings appear unusually high or low or are unstable, there are probably bubbles on the optical surface. Activate the mechanical wiper by pressing the “3” k ey to remove the bubbles. After stable readings are observed for approximately 40 seconds, press Enter to “confirm” the first calibration and then, as instructed, Hit any key to continue.

Dry the sonde and probes carefully and then place the sonde in approximately 300 mL of the second turbidity standard (100 NTU is suggested). Input the correct turbidity value in NTU, press Enter, and view the stabilization of the values on the screen in real-time. As described above, if the readings appear unusually high or low or are unstable, activate the wiper to rem ove bubbles and be sure to wait at least 40 seconds before confirming the calibration. After the readings have stabilized, press Enter to “confirm” the calibration and then, as instructed, Hit any key to return to the Calibrate menu.

Thoroughly rinse and dry the calibration cups for future use.

CAUTION: If the turbidity system has been set up as outlined in Section 2 of the manual, sig n al averaging will be taking place during calibration and the response time of the sensor will be slightly slower than that of the other sensors. This effect makes it critical to observe at least 40 seconds of stable readings prior to “confirming” the calibration. Be particularly careful to tak e y our time during the calibration of the turbidity system.

3.3 DISCRETE SAMPLING

To start taking readings with your 6000UPG, use the Discrete sampling m ode to turn on or turn off the continuous sampling function. Data will be displayed to the screen and optionally saved to internal flash disk memory or to a computer or logger display.

----------------------------------------

1. Conductivity 6. pH

2. DO% 7. Ammonium

3. DO mg/L 8. Nitrate

4. Depth 9. Turbidity

5. ORP A. TDG

Select option (0 for previous menu):

1. Conductivity

Select this option to calibrate the conductivity probe and a second menu will offer y ou the options of calibrating in Specific Conductance, Salinity, or Conductivity. After selecting the option of choice (Specific Conductance is normally recommended), you will be asked to enter the value of the standard used during calibration. Be certain that the units are correct. After pressing Enter,

4-9

you will be able to follow the stabilization of the readings and confirm the calibration w hen the readings are stable by pressing Enter as instructed on the screen.

2. DO %

Select this option to calibrate the oxygen probe in 100% water saturated air. Be certain that the sensor has been thermally equilibrated in water-saturated air, and that the sensor show s stable readings in Discrete Sample mode prior to beg inning the calibration routine, particularly after a membrane change. See section 3.2 for m o re details. Reliev e pressure in the calibration cup, if necessary. Remember that the 6000UPG transport cup is designed to be air tight and the vent

screw must be loosened if the vessel is used as a calibration chamber.

Then enter the local barometric pressure in mm Hg , press Enter, and the dissolved oxyg en sensor will calibrate. Approximately 1 m inute is required for DO % calibration.

3. DO mg/L

Select this option to calibrate the oxygen probe to a water sample which contains a known concentration of dissolved oxygen. For this calibration procedure, the sensor should be immersed in water containing a known concentration (mg/L) of dissolv ed oxy g en, usually determined by performing a Winkler titration. After therm al equilibration, enter this value, press Enter, and the 1 minute calibration procedure will begin.

4. Depth

Select this option to zero the depth sensor. The depth sensor is factory calibrated. It is, however, necessary to zero the sensor with regard to the local barometric pressure. The zeroing procedure should be carried out with the sonde suspended in air. Do not attempt to zero the depth probe when the sonde is immersed. After the depth option is selected, enter 0.00 at the prompt, press Enter and monitor the stabilization of the depth readings. After no changes occur for approximately 30 seconds, press Enter to confirm the calibration. As instructed, press any key to return to the Calibrate menu.

Zeroing the depth sensor by the above protocol (entering 0.00 at the screen prompt) will result in a measurement of the distance between the water surface and the bottom of the sonde bulkhead. This bulkhead is approximately 0.46 ft above the bottom of the sonde guard. Thus, in order for the observed depth to better reflect the distance between the water surface and the probe array, enter

0.46 at the screen prompt instead of 0.00.

5. ORP

Select this option to calibrate the ORP sensor. Immerse the ORP probe in a solution with a k nown ORP value (we recommend Z obell solution) and press Enter. You will be prom pted to enter the ORP value of the solution as found on the bottle. Press Enter, and monitor the stabilization of the

4-10

ORP readings. After no changes occur for approximately 30 seconds, press Enter to confirm the calibration. Then, as instructed, press any key to return to the Calibrate menu.

6. pH

On selecting this option, you will by g iv en the choice of 1-point, 2-point, or 3-point calibrations.

Select the 1-point option only if you are adjusting a previous calibration. If a 2- point or 3-point calibration has been performed previously, you can adjust the calibration by carry ing out a one point calibration. Immerse the sonde in a buffer of k nown pH v alue and press Enter. You will be prompted to type in the pH value of the solution you are using . Press Enter again, and the screen will display real-time readings which will allow you to determ ine wh en the pH reading s have stabilized. Pressing Enter will confirm the calibration. Then, as instructed, press any key to return to the Calibrate menu.

Select the 2-point option to calibrate the pH probe using only two calibration standards. In this procedure, the pH sensor is calibrated using a pH 7 buffer and one additional buffer. A two point calibration procedure (as opposed to a 3-point procedure) can save time if the pH of the m edia being monitored is known to be either basic or acidic. For exam ple, if the pH of a pond is k nown to vary between 5.5 and 7, a two point calibration with pH 7 and pH 4 buffers is appropriate. Three point calibration with an additional pH 10 buffer will not increase the accuracy of this measurem ent since the pH is not within this higher range. Be certain that the buffer and sensor are thermally equilibrated prior to entering pH values.

To begin the calibration, immerse the sonde in pH 7 buffer, as instructed, and press Enter. The screen will display real-time readings which will allow you to determ ine when the pH reading s hav e stabilized. Pressing Enter will confirm the calibration. Following the instructions on the screen, place the sonde in the second pH buffer, input the pH value, press Enter, and view the stabilization of the values on the screen in real time. After the readings hav e stabiliz ed, press Enter to confirm the calibration. Then, as instructed, press any key to return to the Calibrate menu.

Select the 3-point option to calibrate the pH probe using three calibration solutions. In this procedure, the pH sensor is calibrated with a pH 7 buffer and two additional buffers. The 3 point calibration method should be used to assure maximum accuracy when the pH of the media to be monitored cannot be anticipated. The procedure for this calibration is the same as for a 2 point calibration, but the software will prompt you to select a third pH buffer to com p lete the 3 point procedure. Be certain that the buffer and sensor are thermally equilibrated prior to proceeding with the calibration.

7. Ammonium

On selecting this option, you will by g iv en the choice of 1-point, 2-point, or 3-point calibrations for your ammonium (NH

) sensor.

Select the 1-point option only if you are adjusting a previous calibration. If a 2- point or 3-point calibration has been performed previously, you can adjust the calibration by doing a one point calibration. Immerse the sonde in any solution of k nown ammonium concentration and press

4-11

Enter. You will be prompted to type in the NH

value (in mg/L of NH4-N) of the solution you are

using. Press Enter again, and the screen will display real-time readings which will allow y ou to determine when the NH4+ readings hav e stabiliz ed. P ressing Enter will confirm the calibration.

Select the 2-point option to calibrate the NH both as close as possible to the temperature of your environm ental sam ple. In this procedure, the

sensor is usually calibrated using solutions which contain 1 and 100 mg/L of NH4-N . Be

certain that the calibration solution and sensor are thermally equilibrated prior to entering NH

probe using only two calibration standards which are

values. To begin the calibration immerse the sonde in the 1 mg/L standard, press Enter, input the NH

-N

value, and again press Enter. The screen will display real-tim e reading s w hich w ill allow y ou to determine when the sensor has stabilized. Pressing Enter will confirm the first calibration. Following the instructions on the screen, place the sonde in the second NH

standard, press Enter,

input the correct concentration value, again press Enter, and view the stabilization of the values on the screen in real time. After the readings have stabiliz ed, press Enter to confirm the calibration. Then, as instructed, press any key to return to the Calibrate menu.

Select the 3-point option to calibrate the NH

probe using two calibration solutions, one at

ambient temperature and one at a temp erature sig nificantly different from ambient. The 3-point calibration method should be used to assure maximum accuracy when the temperature of the m edia to be monitored cannot be anticipated. The procedure for this calibration is the same as for a 2point calibration, but the software will prompt you to place the sonde in the additional solution to complete the 3-point procedure. Be certain that the calibration solution and sensor are thermally equilibrated prior to proceeding with the calibration. The recommended order of calibration standards is (1) 100 mg/L standard at ambient tem perature, (2) 1 mg/L standard at ambient temperature, and (3) 1 mg/L standard at a different tem p erature (usually lower) than ambient. For best results, insure a temperature difference of at least 10 C°.

8. Nitrate

On selecting this option, you will be giv en the choice of 1- point, 2-point, or 3-point calibrations for your nitrate (NO those in 7 above for the ammonium sensor, except that the calibrant values are in mg/L of NO instead of NH

) sensor. The procedures for calibration of the nitrate sensor are identical to

-N.

-N

9. Turbidity

On selecting this option, you will be giv en the choice of 1- point, 2-point, or 3-point calibrations for your turbidity sensor.

The 1-point option is used only to zero the turbidity probe. Place the sonde in clear w ater with no suspended solids, and input 0 NTU at the screen prompt. Press Enter and the screen will display real-time readings wh ich will allow y ou to determine when the turbidity readings have stabiliz ed. Press Enter after the readings have stabilized to confirm the calibration and zero the sensor. Then,

4-12

as instructed, press any key to return to the Calibrate menu. This procedure should only be used to update a previous 2-point or 3-point calibration.

Select the 2-point option to calibrate the turbidity probe using only two calibration standards. One of the standards must be clear water (0 NTU) and the other should be in the range of known turbibity for the water to be monitored. For example, if the water to be ev aluated is k nown to be low in turbidity, an appropriate choice of standards might be 0 and 10 NTU. If the water to be evaluated is known to be very cloudy, an appropriate choice of standards might be 0 and 100 NTU.

To begin the calibration, immerse the sonde in the 0 NTU standard, as instructed, and press Enter. It is mandatory that the 0 NTU standard be calibrated first. The screen w ill display real-time readings which will allow you to determ ine w hen the reading s hav e stabiliz ed. P ressing Enter will confirm the first calibration. Following the instructions on the screen, place the sonde in the second turbidity standard, input the correct turbidity value in NTU, press Enter, and view the stabilization of the values on the screen in real-time. After the reading s hav e stabiliz ed, press Enter to confirm the calibration. Then, as instructed, press any key to return to the Calibrate menu.

Select the 3-point option for maximum accuracy ov er the entire rang e of 0 to 1000 N TU. As for the 2-point procedure, one of the standards must by 0 NTU. Because of the linearity characteristics of the sensors, we recommend that the other two standards have turbidity v alues of 10 and 100 NTU. However, the user can select any values w hich are deemed appropriate. The procedure for this calibration is the same as for a 2-point calibration, but the software will prompt you to place the sonde in the additional solution to complete the 3-point procedure.

For all turbidity calibration procedures, be certain be certain that the standard and sensor are thermally equilibrated prior to proceeding with the calibration. Remember that all multipoint

turbidity calibrations must be done in order from 0 NTU and up. In this example, do 0 NTU, then 10 NTU, and finally 100 NTU.

NOTE: You will see reference to TDG (total dissolved gas) in the Sensor setup menu. This is for possible future upgrade and is not currently available for your 6000

UPG.

During activation of certain sensors, you will be ask ed to select parameters associated with the operation of the sensor or with calculations made from data acquired by the sensor. Sensors for which additional choices are necessary are described in detail below.

1. Conductivity

After activation of the conductivity sensor, you w ill be ask ed to enter the constant associated w ith the calculation of total dissolved solids (TDS), a parameter which is calculated from specific conductance. The default value of this parameter is 0.65 and any change to the v alue will be show n in parentheses when the prompt appears.

NOTE: If this parameter is disabled, any other parameter which is calculated using conductiv ity will also be disabled.

2. DO

After activation of the dissolved oxygen sensor, y ou w ill be ask ed to enter the D O Warm up time associated with the Rapid Pulse Dissolved Oxygen Sensor. The default value of 40 seconds provides adequate warm-up for m o st applications while m aintaining good battery life in long-term unattended sampling studies. While very long warm-up setting s may marginally increase the accuracy of the readings, their selection will reduce battery life.

A. Turbidity

After activation of the turbidity sensor, you will be ask ed to enter the number of wipes associated with mechanical cleaning of the sensor optics prior to a reading being tak en. Normally, the default value of 1 is suitable, but in some applications where the potential for fouling is great, a g reater number of cleaning cycles m ay be necessary . A dditional wiping of the probe face w ill reduce battery life.

After entering the number of wipes, you will be prompted to enter the Number of Samples to Average. Entry of higher numbers such as 8 will result in g reater smoothing of the data and a more average view of the turbidity in your sample, but with slightly reduced response time. Entry of lower numbers such as 1 will result in jumpier readings w hich reflect the momentary turbidity.

5. PC6000 SOFTWARE

NOTE: If you have purchased Ecowatch for Windows for use with your Model 6000UPG, consult the Help selection in the top menu bar if you have questions on the use of this powerful Windows-based software. The following section deals with the MS-DOS-based PC6000 which is offered with all YSI logger/sampler products at no charge.

5.1 Introduction

The PC6000 program is very useful in the operation of the 6000UPG. This PC based software can be used with any IBM- compatible computer.

PC6000 enables you to:

• Configure and deploy the sonde

• Retrieve and process data from the sonde

• Capture data from the sonde

• Create a variety of reports and plots

• Print reports and plots

• Save reports and plots to disk

• Export data to other programs

The PC6000 program is completely menu-driven and easy to use. There are nine m enus, but beginning users can generate reports and plots using only two menus.

Use the arrow keys to move the cursor and hig hlig ht menu options. Use the Enter key to select a highlighted m enu option. Use the Esc key to return to a previous screen.

When each menu option is highlighted, a short, descriptive help line is display ed at the bottom of the screen.

5.2 INSTALLING THE PC6000 SOFTWA R E

The PC6000 software is provided with every 6000UPG and is located in the back of this instruction manual. Use this software if you have an IB M-compatible PC with at least 300 KB of RAM and

5-1

DOS 3.0 or later. Additional RAM and the presence of a math co-processor will improve the operation of the program, but are not required.

NOTE: PC6000 imposes no limit on the number of lines a report can have, but after g enerating a report, only the last 300 to 2500 lines can be viewed, depending on available RAM.

A graphics adapter is required for operation of the plotting feature. One RS- 232 port (also called a comm port or serial port) is required to communicate with the sonde and to capture data files. This port must be either com1 or com2 .

If your system is not I B M-compatible, use a terminal em ulation prog ram with your computer.

On IBM compatible com puter sy stems with a hard disk drive see section 2.3 for installation instructions:

On systems with two floppy disk s proceed as follow s:

If necessary, exit whatever program or shell is running.

1. Make sure your computer is at the A or A:\ prom pt.

2. Make sure your DOS system disk is in driv e A.

3. Place a new disk in drive B and format it: F OR MAT B:

4. Place the original PC6000 software diskette in drive A.

5. Copy the software onto the new disk: COPY A:*.* B:

6. Store the original PC6000 software diskette in a cool clean place, away from magnets, video screens, electronic and electrical equipment and cords.

7. When you want to use the software, put the copy of the PC6000 software into drive B, put any data disk into drive A, and type: B:PC6000

Once PC6000 has loaded, the program disk can be rem ov ed from the disk drive. The disk must be reinserted into the drive prior to exit from the Setup menu if any chang es hav e been made. This will allow the program to update the configuration file on the disk.

NOTE: If you have a non-standard video adapter and m onitor (rare except on CAD work stations) you will also need to:

1.) Put your video adapter into a compatible (standard) video m ode. Ty pically the manufacturer of the video adapter provides a program or utility to set the v ideo mode.

2.) Type PC6000 -V to run the program. This tells PC6000 to send video output through the computer BIOS (built-in firmware), rather than directly to v ideo m emory. This procedure slows down the video output somewhat, but guarantees compatibility.

5-2

5.3 THE SONDE MENU

The Sonde option of the PC6000 software is covered in detail in Section 4 of this manual. This option emulates a VT 100 terminal which makes a direct connection between the sonde and y our PC. Selecting this option will allow you to access and set up the sonde.

5.4 THE FILE MENU

Choosing File from the PC6000 menu bar allows y ou to specify and customize reports and plots based on data which has been captured from the sonde. Select File from the menu bar, and press Enter.

Filename: *.dat

At this prompt, press Enter. A list of all data files in the current directory will be displayed. Select the file you wish to retrieve from the list. I f only one data file exists, that file w ill be loaded automatically.

To retrieve files stored on another drive or directory, at the filename: prompt, type the source drive and directory and press Enter.

I f formula options for the highlighted parameter exist, they will be displayed when pressing Enter while the formula is hig h lig hted.

Inputs:

This option is reserved for future software enhancements.

5-6

Compensate:

Select this option to compensate a data file for long term sensor drift. This com pensation procedure is also commonly called Post-Calibration.

Example: Dissolved oxygen data can be collected periodically throughout a long term deploy ment using a separate, freshly calibrated DO meter. This independent data can then be used to compensate the 6000

UPG data for the small sensor drift which normally occurs ov er time.

NOTE: The setup menu options for date format, date separator, time separator, and radix separator, all apply here. The date, time, and value are separated from each other by spaces. Lines w hich do not match the above format are ig nored.

To create a compensation file, use a word processing program or follow the procedure below. The file must be simple ASCII. In WordPerfect you use the DOS Text Out feature. In Word, sav e as file type Text Only (*.TXT). From DOS, proceed as follows:

1. Issue the DOS command "COPY CON DO.CMP".

2. Type all the lines in your file (make sure each line is correct before y ou press Enter for that line).

An example line would look like this:

12/31/92 23:59:59 100

3. After the last line has been typed and entered, hold Ctrl and press Z, then press Enter.

4. The message 1 File(s) copied will be displayed.

NOTE: If only one data point is entered into the compensation file, all data after that date and time will be corrected. If more than one data point is included in the com pensation file, data betw een points will be corrected linearly.

To enter the compensation filename, press TAB while the highlight cursor is on com pensate. The highlight cursor will mov e to the right. Enter the path and file name.

Example: C:\DO.CMP Enter.

When you enter a compensation filename, the prog ram performs a test load of that compensation file. A summary is display ed so y ou can v erify the file structure. The sum mary includes how many lines were accepted, rejected, or blank; the total number of lines, and the earliest and latest date.

If you compensate a constant used in calculating one param eter, y ou must also compensate the same constant if you use it to calculate other parameters. A total of 1000 compensation points is allowed for any single report or plot.

5-7

Appendix E of this manual is an application note which will be very helpful as y ou prepare for data collection to be used to compensate 6000

UPG data.

Enter title line

5-8

Select this option to assign a title which will appear on all reports and plots.

First sample was at: Enter start time: Enter stop time: Last sample was at:

Select these options to view start and stop times of the file, and specify portions of the file to report or plot. The first and last line of this block of information indicates the actual start and stop time of the current file. You can identify any segment of time from within a file to report and plot data. For example, if the duration of the deployment was fiv e day s, but y ou wish to see a report and plot for only day three, simply enter the start and stop dates and times associated with day three. Even though all five days of data are retained, reports and plots will show only day three.

Logging interval was: Enter averaging interv al:

This option shows the sampling interval which was in effect throughout the deploy m ent. You may choose to average several data points together for reporting and plotting . For example, if the 6000

UPG readings were captured every 900 seconds (15 m inutes) during the deploy m ent, you might

want the reports and plots to average four of these readings together so that the inform ation can be reported or plotted on an hourly basis. To do this, define an averaging interval of 3600 seconds.

X-axis time per screen:

Select this option to specify the time interval on the X- axis. This line is only applicable when Date + Time have been defined for the X-axis (see Parameters above). You can define the width of a given plot screen in minutes by changing the number of minutes in this option.

Cross-parameter style:

Select this option to choose one of four plot styles. This option is only applicable if a parameter other than Date + Time is selected for the X-axis (see Parameters above).

5-9

An averaged plot (AVG) assumes a correlation between the X-axis parameter and the Y axis parameters. The averaged plot divides the X axis into 100 equal- siz ed m emory bins. Each sample is tallied into the appropriate memory bin based on its X-axis value. When finished, the average value for each Y-axis parameter in each memory bin is displayed.

A sequential plot (SEQ), plots each point successively as it comes from the data file. A sequential plot provides more detail on the data than an averaged plot, but can appear rather messy.

The increase (INC) and decrease (DEC) plots are types of sequential plots. An increasing plot only displays points when the X-axis values are increasing. A decreasing plot only display s points when the X-axis values are decreasing. The increasing and decreasing sequential plots are especially useful if you are profiling and display depth on the X axis. Thus the plot shows only the time in which the sonde is being lowered or raised.

Cross-parameter bins: 100 (maximum xxxx)

Select this option to set up the number of bins which will appear on the X-axis. This feature only applies to reports and averaged plots (see above) with a parameter other than Date + Tim e on the X axis. Changing this value modifies the num ber of bins into which the X-axis is divided. The smaller the number of bins, the wider and more general is the plotted information. The maximu m number of allowable bins varies with the capability of y our computer system, and is displayed in parentheses.

Parameters per plot:

Select this option to setup the number of parameters which will be plotted tog ether. If you choose 1, there will be an individual X and Y axis displayed for each selected parameter. Select any number of parameters per plot, (from 1 to 4) w hich prov ides y our data w ith the best plot presentation.

5.6 DATA CAPTURE / REAL-TIME SETUP

Once the Real-time mode has been properly set up, you will be able to view the data in real-time as it is taken in the Discrete Sample mode by the sonde. Each reading is display ed at the bottom of the real-time screen, and plots are updated with the arrival of each data point. In addition, the data will be automatically stored to the disk drive (hard or floppy ) which y ou select. The setup process is not difficult, but you should follow the instructions in the following section exactly to be sure of successful operation in this mode.

STEP 1. Access the Sonde from the PC6000 menu bar and Start sampling. Make certain that the parameters which you want to view in real time and are display ed correctly. Adjust these parameters, if necessary, via the Report Setup menu of the Sonde software. Once the proper parameters are displayed to the screen, exit the Sonde menu structure by pressing F10 and return to the menu bar of the PC6000 software.

STEP 2: Select Setup from the PC6000 menu bar, and then Data capture setup, pressing Enter after each entry. Access the Parser of this menu with the arrow keys and make certain that it is set to 6000. If not, type 6000 at the prompt, and press Enter. Next access the Site Name portion of the menu and enter any appropriate name. This nam e is prov ided for identify ing purposes only . It is displayed on the File Header Menu, and it appears on the Real-Time plot screen and Real- Tim e plot printout. Now access the Filename portion of the menu and enter the nam e of the file under which you wish your data to be stored, and press Enter. Now access the Auto-configure entry of the menu, and press Enter. There will be a 5-10 second delay while the PC6000 software exam ines the sonde software to determine the parameters which you hav e decided to v iew in real- time. When the process is complete, the these parameters will appear in the list in the lower portion of the Data

capture setup menu.

STEP 3: Set up the display which will be viewed in real-time. First, set the X-axis time per screen in minutes. Next, set the Parameters per plot which can be a value from 1 to 4. Finally,

set the Beep notification to indicate the acquisition of either good data, bad data, or all data (both). Bad data is defined as that which, when arriving from the sonde, contains errors in the communication protocol and is rarely observ ed. I f y ou prefer, you can eliminate the beep function completely by selecting off. B e sure to press Enter after each entry.

STEP 4: Set the scaling for each of the parameters in the lower right portion of the m enu. There is no automatic scaling in this mode, so y ou should select the m anual scaling ranges which will result in meaningful display of your data. These selections w ill becom e easier w ith experience. U se the Tab key to move from Minimum to Maximum and the arrow keys to mov e v ertically w hen carrying out this operation. Be sure to press Enter after each scaling entry.

STEP 5: After entering scaling factors, exit to the PC6000 menu bar by pressing Esc twice. Then access the Sonde portion of the PC6000 menu and press Enter. Type “Menu” at the # prompt and press Enter. Select the Run menu, and begin sampling at the samp le interv al which is suitable for

you study. While the discrete sample mode is still operative, exit. to the PC 6000 menu bar by

pressing F10 (do not press Esc or the sampling will be terminated).

STEP 6: From the PC6000 menu bar, select Real-Time and press Enter. The Discrete Sample

data from the sonde will be plotted on the display and will be logg ed to disk automatically under your designated file name.

COMMON CAUSES OF ERRORS IN REAL-TIME MODE:

1. The “Parser” is not set to “6000”. Set the Parser to “6000”

2. You have selected more parameters in the Sonde Report Setup than can be viewed on the

computer screen. Remove tim e and date and/or other less important parameters in the Report Setup Menu so that all selected parameters are visible in Discrete Sample display.

3. The name which you entered for your data file already exists on your storage disk, but the file

format for the initial study is different from the current file form at. C hang e the name of the data file or delete the existing data file of this name from y our disk .

4. You exited the Discrete Sample mode of the sonde software using Esc rather than F10.

Return to the Sonde menu and select Run. Restart the Start sampling mode and exit with

F10 to the PC6000 menu bar. Choose Real-Time and press Enter.
