2.3 SONDE SETUP In the following section, you will be provided with step-by-step instructions on how to get your 6000UPG up and running. We recommend following the steps in the order listed. However, depending on your sonde configuration and the optional sensors which you have purchased, some of the steps may not apply to your setup. If so, simply skip to the next step in the protocol which is relevant to your application. STEP 1.
3. Follow the procedure described below to install a new membrane on the dissolved oxygen sensor tip. A. Hold the probe in a vertical position and apply a few drops of KCl solution to the tip. The fluid should completely fill the small moat around the electrodes and form a meniscus on the tip of the sensor. Be sure no air bubbles are stuck to the face of the sensor. If necessary, shake off the electrolyte and start over. A B. Secure a membrane between your left thumb and the probe body.
5. Locate the plug which seals the DO.C.T. port on the sonde. Using the hex driver to assist you, remove the plug. 6. Install the 6030 probe into the sonde as described below. A. Apply a very thin coat of O-ring lubricant (supplied in the 6040 Maintenance Kit) to the O-ring on the connector side of the probe. Insert the probe in the port marked DO.C.T. B. With the connectors aligned, screw down the probe nut, making sure that the probe and sonde connectors are fully meshed.
STEP 2. INSTALL OTHER PROBES If you have purchased any optional YSI probes, follow instructions provided below for all items other than the 6029 conductivity/temperature sensor which is installed in an identical fashion to the 6030. The 6031 pH, 6032 ORP, 6033 low ionic strength pH, 6084 nitrate, and 6083 ammonium probes can be ordered as options and do not require factory installation (see Section 4.7 for software setup).
3. Using the hex driver (supplied in the YSI 6040 Maintenance Kit), remove the probe guard mounting screws from the sonde. Set the probe guard and mounting screws aside. CAUTION: Do not remove the two allen screws above the guard. Do Not Remove These Screws Guard 4. Locate the plug which seals the port ISE-1 or ISE-2 on the sonde. pH probes must be installed in the ISE-1 port; ORP probes must be installed in ISE-2 port. Using the hex driver to assist you, remove the plug. 5.
YSI 6083 Ammonium Probe YSI 6032 Nitrate Probe Follow these instructions to prepare your new probe and install it in the Model 6000UPG.

2. That parameter must be activated in the Report section of the Main Menu. Select 4-Report from the Main sonde menu. The Report Setup menu will be displayed.
3. BASIC OPERATION In the previous Section, you learned how to install probes and set up the PC6000, Ecowatch for Windows, and 6000UPG sonde software. In this section, you will learn how to calibrate and run the Model 6000UPG and how to view your data on a computer display. If you choose to use your 6000UPG with a 610-series display/logger, refer to the operations manual for the 610 to obtain similar instructions to those provided below. 3.
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 6000UPG. Because the calibration cup fits over the outside of the sonde probe guard, it is not recommended or necessary to remove the probe guard 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.
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 may be necessary. Similar prompts will be displayed for calibration of all parameters.
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 “wakes it up” and has no visible effect on the display. The next keystroke after the unit is “awakened” will be input to the software in the intended manner.
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 water or a wet sponge in the bottom of the Calibration Cup or Transport Cup.
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 readings with time.
AMMONIUM (NH4+) and NITRATE (NO3-) 3-POINT WARNING: AMMONIUM AND NITRATE SENSORS CAN ONLY BE USED AT DEPTHS OF LESS THAN 50 FEET (15 METERS). USE OF THE SENSORS AT GREATER DEPTHS IS LIKELY TO PERMANENTLY DAMAGE THE SENSOR MEMBRANE. NOTE: The calibration procedures for ammonium and nitrate are similar to pH except for the reagents in the calibration solutions. Suggested values for calibrants are 1 and 100 mg/L of either ammonium-nitrogen (NH4-N) or nitrate-nitrogen (NO3-N).
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 time as they stabilize in the solution.
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 remove bubbles and be sure to wait at least 40 seconds before confirming the calibration.
Select the different functions in this menu to become familiar with the Discrete sampling mode. Remember to use Esc or 0 to cancel functions or to back up to the previous display. 1. Start discrete sample Select this option to start discrete sampling. After the initial sampling time interval has passed, data will be displayed on the screen. A single line of data can be logged to flash disk memory by pressing 1. (screen prompt reads '1-LOG last sample').
Select this option to set up a timer to automatically turn off discrete sampling. If you begin a discrete sample and forget to turn it off later, battery life will be greatly reduced. For this reason, the Auto-stop timer can be set up to automatically turn off any active discrete sample if it has been left on for a specified period of time. Simply type in what you feel is an appropriate amount of minutes, and the program will turn off discrete sampling after that many minutes have passed.
3.4 UNATTENDED SAMPLING The Unattended Sampling Mode is designed to log readings of all user-defined parameters at intervals you specify. The 6000UPG can be deployed for weeks at a time using this feature. Throughout the deployment, data is stored to internal flash disk memory. This data can be uploaded to the PC6000 software upon completion of the study, or at anytime during the study without stopping the logging. Select 1. Run from the sonde Main menu. The Run menu will be displayed.
NOTE: The time entry must include not only hours and minutes, but also seconds. For example, if you want to start a study at 8 AM, you must enter 8:00:00, and not just 8:00. The software will prompt you with a beep if the time is entered incompletely. You will be asked if all start-up information is correct. Check the information carefully and, if you want to change something, press “N”. If all information is correct, press “Y”.
3.5 RETRIEVING DATA FROM THE 6000UPG Attach the PC cable to the 6000UPG. Connect the other end of the cable to the serial port of your computer. Run the PC6000 software and select Sonde from the top-line menu using the arrow keys. Sonde File Setup Real-Time Exit PC6000 NOTE: If communication with the sonde fails, first check all cable connections and the comm port information under Setup of the PC6000 top-line menu.
NOTE: If unattended sampling has already stopped automatically because the duration you entered earlier has expired, press Esc twice to return to the Main menu. Press “Y” and Enter to stop the Unattended study. Return to the sonde Main menu using the Esc key. Select 3.

6. PRINCIPLES OF OPERATION 6.1 CONDUCTIVITY The 6000UPG utilizes a cell with four pure nickel electrodes for the measurement of solution conductance. Two of the electrodes are current driven, and two are used to measure the voltage drop. The measured voltage drop is then converted into a conductance value in milli-Siemens (millimhos). To convert this value to a conductivity value in milliSiemens per cm (mS/cm), the conductance is multiplied by the cell constant which has units of reciprocal cm (cm-1).
MEASUREMENT AND CALIBRATION PRECAUTIONS (1) When filling the calibration vessel prior to performing the calibration procedure, make certain that the level of calibrant standard is high enough in the calibration cup or beaker to cover the entire conductivity cell (approximately 500 mL). (2) After placing the sonde in the calibration solution, agitate the sonde to remove any bubbles in the conductivity cell.
deviation may also be due to fouling of the platinum ORP sensor. This problem can usually be corrected by cleaning the platinum ring according to the manufacturer’s instructions. To determine whether the sensor is functioning correctly, place the ORP probe in 3682 Zobell solution and monitor the millivolt reading. If the probe is functioning within specifications, the ORP reading should be within the range of 210-250 mv at normal ambient temperature.
6.4 pH The 6000UPG employs a field replaceable pH electrode for the determination of hydrogen ion concentration. The probe is a combination electrode consisting of a proton selective glass reservoir filled with buffer at approximately pH 7 and a Ag/AgCl reference electrode which utilizes gelled electrolyte. A silver wire coated with AgCl is immersed in the buffer reservoir.
point where plots of pH vs. mv at different temperatures intersect (the isopotential point) must be known. Using standard pH determination protocol, the 6000UPG software assigns the isopotential point as the mv reading at pH 7 and then calculates the intercept using this assumption. Once the slope and intercept to the plot of pH vs. mv are assigned at the new temperature, the calculation of pH under the new temperature conditions is straightforward, and is automatically carried out by the sonde software.
depth probe. For example, a change of 1 mm of Hg in barometric pressure will change the apparent depth by approximately 0.045 ft (0.012 m). 6.6 TEMPERATURE The 6000UPG utilizes a thermistor of sintered metallic oxide which changes predictably in resistance with temperature variation. The algorithm for conversion of resistance to temperature is built in to the 6000UPG software, and accurate temperature readings in degrees Celsius, Kelvin, or Fahrenheit are provided automatically.
METHOD OF OPERATION Standard Clark dissolved oxygen sensors which are marketed by YSI and other manufacturers are continuously polarized at a voltage sufficiently negative to cause oxygen (which diffuses through the Teflon membrane) to be reduced to hydroxide ion at the cathode and silver metal to be oxidized to silver chloride at the anode. The current associated with this process is proportional to the oxygen present in the solution outside the membrane.
If this calibration method is employed, place the sonde into this known-value solution and input the value (in mg/l) into the 6000UPG software after the reading has stabilized and then, after the reading has stabilized (2-5 minutes). If the Percent Saturation method is selected, the sonde is simply placed in a calibration cup which contains a small quantity of water or a damp sponge. The probe sensor should not be in the water for this calibration procedure.
MEASUREMENT AND CALIBRATION PRECAUTIONS (1) If water-saturated air is used as the calibrating medium, make certain that both the DO reading and the temperature have stabilized (10-15 minutes) before starting the calibration sequence. A wet thermistor can indicate artificially low temperature readings due to evaporation and this situation will result in poor temperature compensation and inaccurate readings. (2) Insure that the calibration cup being used is vented or pressure released.
The slope, offset, and isopotential point drift slowly, and the probe should be recalibrated periodically. All ion selective electrodes are subject to the interaction of species with the sensor membrane which are similar in nature to the analyte. For example, chloride ion binds in this way to the nitrate membrane and produces positive nitrate readings even when no nitrate is present in the medium.
MEASUREMENT AND CALIBRATION PRECAUTIONS (1) The temperature response of ion selective electrodes is not as predictable as that of pH sensors. Therefore, be sure to carry out a 3 point calibration the first time you use the probe. This will provide a default setting for the effect of temperature on your particular sensor. After this initial calibration, you can use the less time-consuming 2 point and 1 point routines to update the 3 point calibration.
per decade for YSI sensors. This slope value is determined by calibration with two solutions of known ammonium concentration (typically 1 mg/L and 100 mg/L NH4+-N). The slope of the plot of log (ammonium) vs. voltage is also a function of temperature. The slope changes by a factor that is the ratio of the absolute temperature of calibration to absolute temperature of measurement. The point where this new plot of log(ammonium) vs. voltage intersects the calibration plot is called the isopotential point.
certain to occur. The extent of the drift will vary depending on the age of the probe, the flow rate at the site, and the quality of the water. For all monitoring studies using ion selective electrodes, the user should acquire a few “grab samples” during the course of the deployment for analysis in the laboratory by chemical means or with another ammonium sensor which has been recently calibrated.
6.10 TURBIDITY Turbidity is the measurement of the content of suspended solids (cloudiness) in water and is typically determined by shining a light beam into the sample solution and then measuring the light that is scattered off of the particles which are present. For turbidity systems capable of field deployment, the usual light source is a light emitting diode (LED) which produces radiation in the near infrared region of the spectrum. The detector is usually a photodiode of high sensitivity.
readings. Note that YSI offers 100 NTU turbidity calibrant as a standard product (6073) and that this standard can be quantitatively diluted with turbidity-free water to provide a 10 NTU calibrant suspension. The overall sensitivity (slope) of the optical sensor is generally less susceptible to drift than its offset (probe output at 0 NTU). The 1 point calibration is designed to reset this offset without affecting the slope and thus provide more accurate performance in water of low turbidity.
For unattended sampling applications, selection of 8 at the Number of Samples to Average prompt results in a somewhat different data processing sequence. In this case, the 6000UPG will take 8 turbidity readings 4 seconds apart at the time the unit wakes up to record a reading. The software will calculate a simple average of these 8 readings and log this value to memory when the final measurement of all parameters is complete.
7. MAINTENANCE A Model 6040 Maintenance Kit is available for use with the 6000UPG. The kit includes several items which will be helpful or necessary in performing the proper routine maintenance on the 6000UPG. The 6040 Maintenance Kit includes a variety of O-rings, a hex driver, replacement hex cap screws, 2 cleaning brushes, O-ring lubricant, and 2 replacement pressure caps for sealing the sonde cable connector.
BATTERY CHAMBER When changing batteries, always check the inside of the battery chamber to assure that no water has seeped into the chamber. If the chamber has become wet, dry the chamber thoroughly with compressed air, a clean cloth, or paper towels. Battery Lid Dry and clean the battery chamber lid with a clean cloth. Before reinstalling the lid, place a very thin coat of O-ring lubricant on the lid O-ring.
CABLE CONNECTOR PORT The cable connector port at the top of the sonde should be covered at all times. While communicating with the sonde, the installed cable should be securely tightened in place. By so doing, it is assured that a proper connection is being made and moisture and possible contaminants are prevented from entering. Cable Connector Port When a communications cable is not connected to the cable connector port, the pressure cap supplied with the instrument should be securely tightened in place.
7.2 PROBE MAINTENANCE Once the probes have been properly installed, regular cleaning and oxygen probe membrane changes are required. 6029 COND/TEMP & 6030 DO/COND/TEMP PROBES For best results, it is recommended that the KCl solution and the Teflon membrane at the tip of the 6030 probe be changed prior to each sonde deployment. See Section 2.2. After removing the used membrane from the tip of the 6030 probe, examine the electrodes at the tip of the probe.
CAUTION: Be sure to: (1) Use only the sanding disks provided in the 6035 maintenance kit in the resurfacing operation and (2) Sand in a direction parallel to the gold electrode. Not adhering to either of these instructions can seriously damage the electrodes. NOTE: If this procedure is unsuccessful, as indicated by improper probe performance, it may be necessary to return the probe to an authorized dealer service center. See Appendix C for contact information.
DEPTH SENSORS The depth sensors are factory installed options which are located inside the sonde body. There is a small plastic fitting which protects the threads of the depth probe port. Before each sonde deployment, inspect this plastic fitting and clear any obstruction which may have clogged it. In the event that the plastic hose fitting is damaged or missing, a replacement can be found in the 6040 Maintenance Kit.
6026 TURBIDITY PROBE The 6000UPG turbidity probe requires only minimal maintenance. After each deployment, the optical surface on the tip of the turbidity probe should be inspected for fouling and cleaned if necessary by gently wiping the probe face with moist lens cleaning paper. In addition, it is recommended that the wiper be replaced periodically. The frequency of this replacement depends on the quality of water under examination.
8. TROUBLESHOOTING The following tables should be helpful in identifying the cause of the most common difficulties which may occur while operating the 6000UPG.

The bus master then sent the "D0" command to retrieve the data. There were 5 data returned. Since 9 readings should be available, the master continued with "D1" commands and received the remaining data. Master: 1D1! 6000UPG: 1+8.25+6.
SDI12 This command activates SDI-12 mode. This is the only mode that the 6000UPG will respond to any SDI-12 command. To exit to command line, hit any key from the terminal connected to the RS-232 port. The 6000UPG provides a confirmation before exiting. If there is no response within 5 seconds, the 6000UPG will return to SDI-12 mode. 9.4 RS-232 INTERFACE The RS-232 interface is provided through the standard DB25 female connector. The 6000UPG supports XON/XOFF handshaking.
9.6 FILE FORMATS The 6000UPG supports three file formats: PC6000, comma and " " delimited (CDF), and ASCII text. The PC6000 format file is in binary. It contains only basic sensor readings. All readings are in 32-bit IEEE floating point format. For each data, the least significant byte comes first. This file takes the least amount of processing time and has the smallest size. The PC6000 software bundled with the 6000UPG can be used to process the file.
9.7 MODEM SETUP 6000UPG instruments designated UPG3 on the serial label are wired to support a direct modem interface via the YSI 6105 MS-8 to DB-25 male modem adapter. Since modems are so diverse in their default factory configuration, it is often necessary to send a “configuration” string to the modem so it will work properly with the 6000UPG. This is typically done through the use of “AT” command sequences sent to the modem once connected.
2. Answer String This option identifies the string necessary for the modem to take the phone off-hook (answer). For nearly every modem, this string is “ATA” and will not have to be changed from the default value. 3. Password After answering a call, the 6000UPG can prompt for a password before allowing the caller access. When entering a password, the user will be prompted to verify the password before it will take effect. Typing “NONE” at the prompt will remove password protection.

APPENDIX E APPLICATION NOTE SENSOR DRIFT COMPENSATION WITH THE 6000UPG The following application note is designed to facilitate the use of the sensor drift software included in the PC6000 package by providing the user with a specific example. The use of this function is generalized in Section 5.4 of the 6000UPG manual. Situation After laboratory calibration, a user deployed their 6000UPG in a readily-accessible stream on 10/14/92 with the instrument set to log data to memory at 15 minute intervals.
Compensation Procedure (1) For this example, make certain that the data file is present in a subdirectory of the hard drive (C:\PC6000). (2) "Exit" from PC6000 software using the top menu bar. The "C:\PC6000" prompt should be displayed. (3) The user must now write compensation files which contain the above data points and which will be accessed automatically by the PC6000 software. If the "C:\PC6000" prompt is displayed, the files will be located in the same subdirectory as the SRUN7.DAT data file.
(6) After writing the DO and pH compensation files to the C:\PC6000 directory, type "PC6000" at the "C:\PC6000" prompt to re-enter the PC6000 software package. Just as would be done for no compensation, prepare the plot and report output format desired by manipulation of the "Parameters", the "Control Information", and the "Scaling Information". (7) After the format is finalized, re-enter the "Parameters" section of the software.

APPENDIX G SENSOR AND SONDE STORAGE RECOMMENDATIONS The multiparameter equipment associated with the EMS product line from YSI consists of a number of types of sondes which differ in size and function and which, by definition, contain a variety of sensors (or probes) in a compact arrangement where the sensors cannot be separated physically. This arrangement allows the user to concurrently (and conveniently) acquire data from all of these sensors (either in spot sampling or monitoring applications).
The key for interim storage is to use a minimal amount of water so that the air in chamber remains at 100 percent humidity, but the water level is low enough so that none of the sensors are actually immersed. Any type of water can be used in this protocol: Distilled, deionized, or tap. If storage water is inadvertently lost during field sampling studies, environmental water can be used to provide the humidity. Thus, interim multiparameter storage is easy.
dissolved oxygen, pH reference, and pH glass) in the bulkhead. Remove the reference module, store it as described below, and plug the open port with the insert which was provided. Make certain that the dissolved oxygen sensor has an undamaged membrane and electrolyte in place. Place approximately 300 mL of tap water in the storage vessel, insert the sonde, and seal the vessel with the cap and O-ring.
DISSOLVED OXYGEN Rapid Pulse dissolved oxygen sensors should always be stored with a membrane and electrolyte in place and in such a way that the drying out of the electrolyte on the probe face is minimized. For long term storage, the medium should be water rather than the moist air used in interim storage. The long term storage protocol is also dependent on the instrument under consideration. For the 6000UPG, the 600XL, and the 6820, two long term storage methods are equally acceptable.
a level which completely covers the dissolved oxygen and pH probes. Seal the vessel with the cap and O-ring. At the end of the storage time, remove the existing membrane and remembrane the probe using new electrolyte. pH The key to pH probe storage, either short or long term, is to make certain that the reference electrode junction does not dry out.
ORP Long Term Storage: ORP is not available on the Model 600. For the Model 6000UPG, 600XL, and 6820 systems, the recommended long term storage protocol is identical. Remove the probe from the sonde and seal the vacant port with the provided plug. Place the probe in the storage vessel (plastic boot or bottle) which was in place on delivery. The vessel should contain a solution which is 2 molar in potassium chloride. Make certain that the vessel is sealed to prevent evaporation of the storage solution.
APPENDIX H TURBIDITY MEASUREMENTS WITH THE 6000UPG A QUESTION/ANSWER GUIDE TO HELP YOU OPTIMIZE PERFORMANCE AND TROUBLE SHOOT PROBLEMS. Introduction The turbidity system of the Model 6000UPG is characterized by a great deal of flexibility from the point of view of the user.
significant benefit and more than likely will be necessary for most deployments. Even if fouling from chemical or biological sources is not a significant problem in your unattended application, it is likely that bubbles will form on the optical surface during deployment and result in the transmission of erroneous readings. Further, once bubbles have formed, they can remain in place for long periods of time, resulting in corrupted readings for the majority of the study.
Question 4: Should I carry out a 1-point, 2-point, or 3-point turbidity calibration, and what values should I use? Even though the default calibration value in your 6000UPG is reasonably appropriate for the “average” 6026 sensor, you should always carry out some multipoint calibration (2- or 3-point) prior to your first usage to make certain that your system meets the YSI accuracy specifications provided in the 6000UPG manual.
Samples to Average” be set to 8. We feel that this setting will normally produce data which is reflective of the “average” turbidity of field sites, but will not slow the response time so as to result in any significant inconvenience to the user during calibration.
or negative) if the probe is responding correctly from an optical standpoint. If no response is noted, the probe must be returned to YSI Customer Service for repair or replacement. CAUTION: DO NOT ATTEMPT TO DISASSEMBLE THE PROBE YOURSELF. If the probe is functioning properly, replace the probe guard and place the sonde back into 0 NTU water. Activate the wiper or agitate the sonde rapidly to remove bubbles and enter the calibration routine of choice (1-, 2-, or 3-point) from the Calibrate menu.
