SECTION 1 INTRODUCTION

1.1 ABOUT YSI INCORPORATED

From a three-man partnership in the basement of the Antioch College science building in 1948, YSI has grown into a commercial enterprise designing and manufacturing precision measurement sensors and control instruments for users around the world. Although our range of products is broad, we focus on four major markets: water testing and monitoring, health care, bioprocessing, and OEM temperature measurement.

In the 1950s, Hardy Trolander and David Case made the first practical electronic thermometer using a thermistor. This equipment was developed to supply Dr. Leland Clark with a highly sensitive and precise temperature sensor for the original heart-lung machine. The collaboration with Dr. Clark has been critical to the success of the company. In the 1960s, YSI refined a Clark invention, the membrane covered polarographic electrode, and commercialized oxygen sensors and meters which revolutionized the way dissolved oxygen was measured in wastewater treatment plants and environmental water. Today, geologists, biologists, environmental enforcement personnel, officials of water utilities and fish farmers recognize us as the leader in dissolved oxygen measurement.

In the 1970s, YSI again worked with Clark to commercialize one of his many inventions, the enzyme membrane. This development resulted in the first practical use of a biosensor, in the form of a membrane based on immobilized glucose oxidase, to measure blood sugar accurately and rapidly. In the next few years, this technology was extended to other enzymes, including lactate oxidase for applications in biotechnology, health care, and sports medicine.

In the early 1990s, YSI launched a line of multi-parameter water monitoring systems to address the emerging need to measure non-point source pollution. Today we have thousands of instruments in the field that operate with the push of a button, store data in memory, and communicate with computers. These instruments (described in this manual) are ideal for profiling and monitoring water conditions in industrial and wastewater effluents, lakes, rivers, wetlands, estuaries, coastal waters, and monitoring wells. If the instrument has ‘on board’ battery power, it can be left unattended for weeks at a time with measurement parameters sampled at your setup interval and data securely saved in the unit's internal memory. The fast response of YSI’s sensors make the systems ideal for vertical profiling, and the small size of some our sondes allows them to fit down 2-inch diameter monitoring wells. All of YSI’s multi-parameter systems for surface and groundwater feature the YSI-patented Rapid Pulse Dissolved Oxygen Sensor, which exhibits low-stirring dependence and provides accurate results without an expensive, bulky, and power-intensive stirrer.

YSI has established a worldwide network of selling partners in 54 countries that includes laboratory supply dealers, manufacturers' representatives, and YSI’s sales force. A subsidiary, YSI UK, distributes products in the United Kingdom, a sales office in Hong Kong supports YSI’s distribution partners in Asia Pacific, and YSI Japan supports distribution partners in Japan.

Through an employee stock ownership plan (ESOP), every employee is one of the owners. In 1994, the ESOP Association named YSI the ESOP Company of the Year. YSI is proud of its products and are committed to meeting or exceeding customers' expectations.

1.2 HOW TO USE THIS MANUAL

The manual is organized to let you quickly understand and operate the YSI 6-Series drinking water (DW) systems. However, it cannot be stressed too strongly that informed and safe operation is more than just

SECTION 2 6920DW AND 600DW-B SONDES

2.1 GETTING STARTED

The 6920DW and 600DW-B-B Drinking Water Monitoring Systems are multi-parameter, water quality measurement, and data collection systems. Their primary application is the monitoring of drinking water using a flow cell and a free chlorine sensor is provided with each instrument since this parameter is very important in assessing the quality of drinking water. However, these instruments can also be used in a variety of research, assessment, and regulatory compliance applications without a flow cell as long as the user realizes that the performance of the free chlorine sensor will be significantly compromised under these conditions. The primary difference between the “DW” instruments and those provided by YSI for surface and ground water applications is that the oxygen sensor for the standard sondes has been replaced by a free chlorine sensor in the 6920DW and 600DW-B. The free chlorine sensor also requires a different circuit board which is resident in the instrument and this means that “DW” sondes are not capable of dissolved oxygen measurement and, vice versa, standard sondes are not capable of free chlorine measurement even though the probes themselves will fit in either of the instruments. Section 2 concentrates on how to set up operate the “DW” sondes. For the purpose of terminology in this manual it should be realized that a sonde is a torpedo-shaped water quality monitoring device that is placed in the water to gather water quality data. Sondes may have multiple probes. Each probe may have one or more sensors that read water quality data.

The following list contains parameters that your sonde may measure. See Appendix E Specifications for the specific parameters of each sonde.

•Free Chlorine

•Conductivity

•Specific Conductance

•Salinity

•Total Dissolved Solids

•Resistivity

•Temperature

•pH

•ORP

•Turbidity

•Nitrate-N

•Ammonia-N

•Ammonium-N

•Chloride

•Chlorophyll

•Rhodamine WT

This section is designed to quickly familiarize you with the hardware and software components of the “DW” sondes and their accessories. You will then proceed to probe installations, cable connections, software installation and finally basic communication with your Sonde. Diagrams, menu flow charts and basic written instructions will guide you through basic hardware and software setup.

2.3 PREPARING THE SONDE FOR USE

To prepare the sonde for calibration and operation, you need to install probes (sensors) into the connectors on the sonde bulkhead. In addition to probe installation, you need to install a new membrane on the YSI 6572 Free Chlorine Probe. It is highly recommended that you install the free chlorine membrane before installing the probe onto the bulkhead. The next step is providing power for the sondes, through batteries or AC, and then connecting a cable. The four steps necessary for getting your sonde ready for use are listed below.

Step 1 Installing the Free Chlorine Membrane – Section 2.3.1

Step 2 Installing the Probes – Section 2.3.2

Step 3 Supplying Power – Section 2.3.3

Step 4 Connecting a Cable – Section 2.3.4

2.3.1 STEP 1 - INSTALLING THE FREE CHLORINE PROBE MEMBRANE

The 6572 Free Chlorine probe is shipped with a protective cap on the sensor tip which must be removed before proceeding . Handle the probe with care. It is very important not to drop the probe and/or gouge the probe tip. See Section 2.10.2, Probe Care and Maintenance, for information on how often the membrane should be replaced.

Unpack the YSI 6572 Free Chlorine Probe Kit and follow the instructions below.

FREE CHLORINE SENSOR ELECTROLYTE PREPARATION

Open the 6573 membrane kit which was shipped with your instrument and prepare the electrolyte solution. Dissolve the KCl in the dropper bottle by filling it to the neck with deionized or distilled water and shaking until the solids are fully dissolved. After the KCl is dissolved, wait a few minutes until the solution is free of bubbles.

Section 2

Locate the 6035 Reconditioning Kit which was supplied with your 6572 Free Chlorine Probe. Use one of circular sanding disks the 6035 Reconditioning Kit to sand the face of the 6572 Probe according to the following instructions.

•Hold the probe in a vertical position, place a sanding disk under your thumb, and stroke the probe face in a direction parallel to the platinum electrode (located between

the two silver electrodes). The motion is similar to that used in striking a match. Usually 10-15 strokes of the sanding disk are sufficient to remove black deposits on the silver electrodes.

However, in extreme cases, more sanding may be required to regenerate the original silver surface.

•Rinse the probe tip well with purified water to remove dust from sanding.

CAUTION: You must sand your free chlorine sensor as described above prior to installing a membrane to insure the surface tension for probe surface/membrane interface.

Locate the YSI 6574 O-ring Installation Kit which was shipped with your sonde. Note that the kit contains two items – a circular plate with a threaded hole and a cylindrical tool with a screwdriver-style handle as shown in the picture below.

Thread the nut on the end of the 6572 probe into the base plate as shown in the picture below.

Place an o-ring from the 6573 membrane kit in the groove at the bottom of the tool as shown in the picture below left.

Section 2

As shown in the picture below, place the bottom of the o-ring installation tool over membrane/probe face and press down securely.

As shown in the picture below left, roll the o-ring off of the end of the installation tool so that it resides in the o-ring groove of the probe. Be sure to hold onto the O-ring prior to removing the installation tool so that it does not pop out of the groove. Then, as shown below right, remove the installation tool and make certain that the o-ring is centered in the groove on probe end.

As shown in the picture below, use a razor blade or knife to trim away the excess membrane material.

YSI Incorporated Drinking Water Monitoring Systems Operations Manual

2-8

Sondes		Section 2

The pictures below show a properly installed free chlorine membrane. Note that, because the membrane will not stretch, there may be some points where the membrane is slightly “bunched up” in the o-ring groove. This effect is normal and will not affect sensor function. Also note that the presence of bubbles under the membrane is also normal and should not affect probe function

Note the presence of a bubble after installation. This is acceptable for a free chlorine membrane.

`

After installing the membrane, either proceed immediately to the sensor activation protocol described above in the Quick Start Guide or store the probe in a beaker of tap water (NOT deioinized or distilled water) as shown in the picture below to prevent drying out. Be sure to place the probe GENTLY into the beaker to avoid damaging the membrane integrity.

YSI Incorporated Drinking Water Monitoring Systems Operations Manual

2-9

Sondes		Section 2

NOTE CAREFULLY: Users who are accustomed to installing a Teflon membrane on a YSI dissolved oxygen sensor should note that the methods recommended for the Teflon installation are not likely to work well for the free chlorine membrane because this membrane cannot be stretched. Therefore, dissolved oxygen membrane installation techniques which are outline in the manuals for various YSI instruments, including standard 6-series sondes utilizing the 6562 Rapid Pulse DO sensor, are NOT RECOMMENDED for the free chlorine membrane installation.

2.3.3STEP 3 - POWER

The YSI 6920DW and 600DW-B sondes have internal batteries or can run on external power.

In addition, if you have purchased a YSI 650 MDS display/logger or 6500 Process Monitor, attaching your sonde to these instruments will allow your sonde to be powered from the batteries of the 650 or the AC power of the 6500.

POWER FOR LAB CALIBRATION

Using a YSI 6038 (110 VAC) or 6651 (100-240VAC) Power Supply to power the sondes in the lab is often convenient and extends battery life. In addition, AC power will likely be available for many drinking water studies and the 6651/6038 may be the most efficient method of providing power for long term monitoring studies. After attaching the four-pin connector from the power supply to the instrument cable (see below), simply plug the power supply into the appropriate AC outlet.

See Section 2.2, Connecting Your Sonde, for specific information on cables, adapters and power supplies required for connecting your sonde to various devices.

As shown in the picture at left, the 6920DW and 600DW-B have a sonde-mounted cable connector for attachment of cables. Two types of cables are available – a “field cable” in various lengths up to 200 feet and a short 6067B laboratory calibration cable.

To attach a field cable to the sonde connector, remove the waterproof cap from the sonde connector and set it aside for later reassembly during deployment or storage. Then connect your field cable to the sonde connector.

A built-in “key” will ensure proper pin alignment. Rotate the cable gently until the “key” engages and then tighten the connectors together by rotating clockwise. Attach the strain relief connector to the sonde bail. Rotate the strain relief connector nut to close the connector's opening.

Section 2

The other end of the field cable is a military-style 8-pin connector (MS-8). Through use of a YSI 6095B MS-8 to DB-9 adapter, the sonde may be connected to a computer for setup, calibration, real-time measurement, and uploading files.

This MS-8 connector also plugs directly into the 650 MDS display/logger or the 6500 Process Monitor. These instruments contain microprocessors with software which provides the ability to set up and calibrate your sonde sensors in a similar way to that of a terminal interface to a PC.

As an alternative to the field cable for interface to a PC, you may use a YSI 6067B calibration cable for laboratory interaction with the sonde. In this case, simply plug the proper end of the cable into the sonde connector and attach the DB-9 connector of the cable to the Com port of your computer. Note that the 6067B will not interface to a 650 Display/Logger of 6500 Process Monitor

For drinking water studies involving only internal logging of data or real-time display of data on a PC using EcoWatch for Windows software, the 6067B may be the cable of choice.

2.4 ECOWATCH FOR WINDOWS -GETTING STARTED

This section will describe how to get started with EcoWatch for Windows, but detailed information is provided in Section 4, EcoWatch for Windows, or a convenient Windows Help section that is part of the software. It is recommended that you thoroughly read Section 4 or use the Help function for a comprehensive understanding of EcoWatch for Windows.

2.4.1INSTALLING ECOWATCH FOR WINDOWS

EcoWatch for Windows software must be used with an IBM-compatible PC with a 386 (or better) processor. The computer should also have at least 4MB of RAM and Windows Version 3.1 or later.

Place the EcoWatch for Windows compact disk in your CD ROM drive. Select Start, then Run and type d:\setup.exe at the prompt. Press Enter or click on “OK” and the display will indicate that EcoWatch is proceeding with the setup routine. Simply follow the instructions on the screen as the installation proceeds.

2.4.2RUNNING ECOWATCH FOR WINDOWS

To run EcoWatch for Windows, simply select the EcoWatch icon on your desktop or from the Windows Program Menu. For help with the EcoWatch program, see Section 4, EcoWatch or use the Help section of the software.

2.4.3ECOWATCH FOR WINDOWS SETUP

To setup the EcoWatch software for use with a sonde, select the sonde icon on the toolbar, and then the proper Com port (1 or 2) to which your sonde is connected. If the default setting is correct, it does not need to be changed. Click “OK” to open a terminal window.

From the Comm Menu, select the Settings option to check the baud rate. The baud rate should be 9600. If it is not, select 9600 from the list and press Enter.

From the Settings Menu, select the Font/Color and Background Color options to choose a color scheme for the EcoWatch for Windows menus.

2.5 SONDE SOFTWARE SETUP

There are two sets of software at work in any YSI environmental monitoring system. One is resident in the sonde and the other is associated with the interface device (a PC, 650 Display/Logger, or 6500 Process Monitor). If you are using a PC for your initial sonde setup as recommended, you will be using EcoWatch for Windows software which was installed as described above and you should follow the instructions in the section below to prepare your DW sonde for use. If you are using a 650 for sonde interface, see Section 5 for setup and interface instructions. If you are using a 6500 for sonde interface, see the manual which was supplied with this instrument.

Section 2

For PC-based sonde interface, run EcoWatch for Windows and click on the sonde icon, from the toolbar Then select the proper Com port and confirm by clicking OK. A window similar to that shown below will appear indicating connection to the sonde as shown in the figure below. Type “Menu” after the

# sign, press Enter, and the sonde Main menu will be displayed.

If your sonde has previously been used, the Main menu (rather than the # sign) may appear when communication is established. In this case simply proceed as described below. You will not be required to type “Menu”.

If you are unable to establish interaction with the sonde, make sure that the cable is properly connected. If you are using external power, make certain that the YSI 6038 or 6651 power supply or other 12 vdc source is properly working. Recheck the setup of the Com port and other software parameters. Also refer to

Section 6, Troubleshooting.

The sonde software is menu-driven. You select functions by typing their corresponding numbers. You do not need to press Enter after choosing a selection. Type the 0 or Esc key to return to the previous menu.
