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 three major markets: water testing and monitoring, health care, and bioprocessing.

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 the user’s setup interval and data securely saved in the unit's internal memory. The fast responses 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 feature either 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 or an ROX optical dissolved oxygen sensor which exhibits no flow dependence and is extremely stable in long-term deployments.

YSI has established a worldwide network of selling partners in over 50 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.

SECTION 2 SONDES

2.1 GETTING STARTED

The 6-Series Environmental Monitoring Systems from YSI are multi-parameter, water quality measurement, and data collection systems. They are intended for use in research, assessment, and regulatory compliance applications. Section 2 concentrates on sondes and how to operate them during different applications. 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 O, Specifications for the specific parameters of each sonde.

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 6562 DO Probe if you are using this item. It is recommended that you install the DO membrane before installing the probe onto the bulkhead. For membrane changes in the future, you may be able to perform this operation without removing the DO probe. This will largely depend on whether the other installed probes interfere with your ability to install a membrane. The next step is providing power for the sondes, through batteries or line power, and then connecting a field cable. The four steps necessary for getting your sonde ready for use are listed below.

Step 1 Installing the Dissolved Oxygen 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 Field Cable – Section 2.3.4

2.3.1 STEP 1 - INSTALLING THE DISSOLVED OXYGEN MEMBRANE

Note: If you are using a ROX Optical DO sensor for your applications, please skip to Section 2.3.2 at this time.

The 6562 Rapid Pulse Polarographic DO probe is shipped with a protective dry membrane on the sensor tip held in place by an O-ring. Remove the O-ring and membrane. Handle the probe with care. It is very important not to scratch or contaminate the sensor tip. See Section 2.10.2, Probe Care and Maintenance, for information on how often the membrane should be replaced.

Unpack the YSI 6562 DO Probe Kit and follow the instructions below.

Open the membrane kit 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.

PROTECTIVE CAP

The DO membrane can be installed with the DO probe either free or installed in the sonde. Both methods are described in detail below. CAUTION: If you install the membrane with the probe not installed in the sonde, be sure that the protective cap is installed on the probe end away from the sensor face to ensure that the connector is not contaminated with electrolyte.

Section 2

DO MEMBRANE INSTALLATION WITH THE PROBE NOT INSTALLED IN THE SONDE

Remove the protective cap and the dry membrane from the YSI 6562 Dissolved Oxygen probe.

Make sure that the protective cap is installed on the connector end of the probe. Do not allow the electrolyte solution to wet the probe‟s connector and O-ring seal areas. This solution is extremely corrosive to the connector and is difficult to remove.

Before using any electrolyte, wrap a clean, dry paper towel around the capped probe to catch any spilled electrolyte. 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.

Secure a membrane between your left thumb and the probe body. Always handle the membrane with care, touching it only at the ends.

With the thumb and forefinger of your right hand, grasp the free end of the membrane. With one continuous motion, gently stretch it up, over, and down the other side of the sensor. The membrane should conform to the face of the sensor.

Secure the end of the membrane under the forefinger of your left hand.

Roll the O-ring over the end of the probe, being careful not to touch the membrane surface with your fingers. There should be no wrinkles or trapped air bubbles. Small wrinkles may be removed by lightly tugging on the edges of the membrane. If bubbles are present, remove the membrane and repeat steps 3-8.

Trim off any excess membrane with a sharp knife or scissors. Rinse off any excess KCl solution, but be careful not to get any water in the connector.

If you are concerned that electrolyte may have dripped onto the O- ring seal area, probe connector, or bulkhead connectors, rub the area clean with paper towels wetted with Deionized water and then dry the affected area with a final dry towel, compressed air blasts, or rinse with fresh alcohol.

Section 2

DO MEMBRANE INSTALLATION WITH THE PROBE INSTALLED IN THE SONDE

Secure the sonde in a vertical position using a vise or a clamp and ring stand such that the sensors are upright. Remove the probe guard from the sonde.

Remove the old DO membrane and clean the probe tip with water and lens cleaning tissue. Make sure to remove any debris or deposits from the O-ring groove.

Using the dropper bottle of electrolyte supplied, place electrolyte on the DO probe tip until a high meniscus is formed as shown in Figure 8 below.

Figure 8			Figure 9

Hold the membrane so that all four corners are supported, but do not stretch the membrane laterally.

Position the membrane over the probe, keeping it parallel to the probe face as shown in Figure 9 above.

Using one continuous downward motion, stretch the membrane over the probe face as shown. See Figure 10 below. Do not hesitate to stretch the membrane.

Figure 10			Figure 11

Install a new O-ring by placing one side of the O-ring in the groove and rolling into place across the membrane and into the groove on the opposite side of the probe face. Avoid touching the probe face with

your fingers. Once the O-ring is in position, squeeze it every 90 degrees to equalize the tension. See Figure 11 above. DO NOT USE GREASE OR LUBICANT OF ANY KIND ON THE O-RING.

Using a hobby knife or a scalpel, trim the excess Teflon from the membrane, making your cut about 1/8 inch below the O-ring as shown in Figure 12 below. A razor blade can be used for the cut if no knife or scalpel is available.

Figure 12			Figure 13

If the installation has been done properly, the finished product should have no bubbles, wrinkles, or tears as shown in Figure 13 above.

NOTE: Observe the following cautions to assure that your membrane installation is proper:

Secure the sonde tightly so that it will not move during membrane installation.

Wash hands before installation and do not allow finger oils or O-ring lubricant to touch the probe face or the membrane.

Use caution when replacing the probe guard that you do not touch the membrane. If you suspect that the membrane has been damaged, replace it immediately.

2.3.2 STEP 2 - INSTALLING THE PROBES

Remove the calibration cup from your sonde by hand as shown in Figure 14, to expose the bulkhead.

2.3.3STEP 3 - POWER

Some type of external power supply is required to power the YSI 600R, 600QS, 600XL 6820V2-1, and the non-battery version of the 600 OMS V2-1sondes. The YSI 6920V2-1, 6920V2-2, 6600V2-2,

6600EDS V2-2, 6600V2-4, 600XLM, and battery version of the 600 OMS V2-1sondes have internal batteries or can run on external power.

If you have purchased a YSI 650 MDS display/logger, attaching your sonde to the display/logger will allow your sonde to be powered from the batteries or the external power of the display/logger. See Section 3, Displays/Loggers, for power options.

The battery-powered version of this instrument is powered by alkaline batteries, which the user must remove and dispose of when the batteries no longer power the instrument. Disposal requirements vary by country and region, and users are expected to understand and follow the battery disposal requirements for their specific locale.

The circuit board in this instrument contains a manganese dioxide lithium "coin cell" battery that must be in place for continuity of power to memory devices on the board. This battery is not user serviceable or replaceable. When appropriate, an authorized YSI service center will remove this battery and properly dispose of it, per service and repair policies.

POWER FOR LAB CALIBRATION

A YSI 6038 (110 VAC) or 6651 (64-240 VAC) Power Supply is required for sondes without internal batteries when using them with a PC for calibration and setup. Sondes with internal batteries do not require a power supply, but using the sonde with a power supply in the lab is often convenient and extends battery life. Most adapters include a short pigtail for power that plugs into the power supply. After attaching the four-pin connector from the power supply to the pigtail, 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.

INSTALLING BATTERIES

The 600XLM, 6600V2-2, 6600EDS V2-2, 6600V2-4, 6920V2-1, 6920V2-2 and battery version of the 600 OMS V2-1are the sondes that use alkaline batteries for power. A set of batteries is supplied with each of these sondes. If you do not have one of these sonde model types, you may skip this section.

INSTALLING BATTERIES INTO THE YSI 600XLM OR 600 OMS V2-1 SONDES

To install 4 AA-size alkaline batteries into the sonde, refer to the following directions and Figure 33.

Grasp the cylindrical battery cover and unscrew by hand. Then slide the battery lid up and over the bulkhead connector. Insert batteries, paying special attention to polarity. Labeling on the battery compartment posts describes the orientation. It is usually easiest to insert the negative end of battery first and then “pop” the positive terminal into place.

Check the O-ring and sealing surfaces for any contaminants that could interfere with the O-ring

seal of the battery chamber.

CAUTION: Make sure that there are NO contaminants between the O-ring and the sonde. Contaminants that are present under the O-ring may cause the O-ring to leak when the sonde is deployed.

Lightly lubricate the o-ring on the outside of the battery cover. DO NOT lubricate the internal o-ring.

Return the battery lid and tighten by hand.

DO NOT OVER-TIGHTEN.

INSTALLING BATTERIES INTO THE YSI 6600V2-2, 6600EDS V2-2, AND 6600V2-4 SONDES

Figure 35

IMPORTANT SAFETY FEATURE: The 116003 battery lid for the 6600V2-2, 6600EDS V2-2, and 6600V2-4 is equipped with a safety pressure-release valve. The valve will vent off any pressure build up in the battery compartment from waste gas that could be created by battery failure, improperly marked or installed batteries, flooding, and dead or heavily discharged batteries. Pressure from the waste gas can deform the battery compartment and cause the sonde to shatter, projecting fragments from the sonde casing in all directions. People near a sonde that shatters could suffer serious puncture wounds and serious eye injuries. DO NOT defeat this safety feature by blocking the valve or painting over or in close proximity to the valve. DO NOT attempt to disassemble the safety valve.

Install 8 C-size alkaline batteries according to the following directions and

Figure 35.

Using the 9/64” hex driver supplied with the 6600V2-2, 6600EDS V2-2 and 6600V2-4 loosen the battery lid screws.

NOTE: The battery lid screws are captive. It is not necessary to remove them from the lid completely.

Remove the battery lid and install the batteries, as shown. If installing or replacing the batteries, test batteries for proper polarity and voltage and observe the correct polarity before installing the batteries into the battery chamber.

CAUTION: Be sure the orange O-ring is installed in the groove of the lid. The o-ring is designed with retention tabs to prevent it from falling out of the grove during installation. Check the O-ring and sealing surfaces for any contaminates which could interfere with the O-ring seal of the battery chamber. Remove any contaminates present. Also clean the protective O-rings which are located the side of the battery lid. Apply a small amount of grease to the threads of each screw to prevent binding. See the next section and Figures 35A through 35L for details on proper installation of the battery lid o-ring.

The updated face seal for the 6600 sonde battery lid incorporates six retaining tabs to hold the face seal in the seal groove during installation, allowing consistent and effective sealing after battery replacement. In order for this feature to work properly, the retaining tabs must be correctly seated in the battery lid‟s seal groove to prevent it from becoming dislodged during handling. If the seal is not installed correctly it can fall out of its groove during battery lid installation and then can be crushed during assembly. This may cause damage to the seal and cause battery compartment flooding when the sonde is deployed. The following procedure is a recommended method to properly retain the seal in its groove:

1. Place seal on the battery lid groove so that it

Section 2

2.Press two of the outermost retaining tabs down into the groove. It should be clear that the retaining tabs have recessed into the groove along with the seal so that the tabs outermost edges are at or below the battery lid‟s mounting surface.

Figures 35C and 35D

3.Press the remaining two outermost retaining tabs into the groove and check to make sure the tabs have been recessed as before. Verify that the other two previously seated retaining tabs have not been forced from their position in the groove.

Figures 35E and 35F

4.Place your thumbs on the seal about a ¼” or so from the sides of the center retaining tab and press the seal down into the groove while sliding your thumbs towards each other. This stretches the seal to fit the profile of the groove allowing the center tab to be seated properly. You may need to use the tip of one of your thumbs to finish pressing the tab into place.

Figures 35G and 35H

5.Press the remaining middle retaining tab into the groove as before and verify that none of the other retaining tabs have been forced from their positions in the groove during this part of the seal installation.

Figures 35I and 35J

6.To ensure that all the retaining tabs are properly seated in the seal groove you can apply pressure to the seal forcing it into the groove at the location of each tab. This will further seat each tab into the groove allowing it to capture the seal.

Lightly lubricate the o-rings on the outside of the battery cover. DO NOT lubricate the orange internal o- ring.

Return the battery lid and HAND tighten the screws with the hex driver until snug. DO NOT OVER TIGHTEN.

CAUTION: Over-tightening the screws may cause the battery compartment to flood. Do NOT use power tools to tighten the battery lid screws.

With the battery cover installed and secured, check the battery voltage in the sondes Status Menu. The voltage must be 12.0 volts or higher with new cells. A voltage less then 12.0 volts could indicate that a cell was installed upside down or that one of the cells is not at full strength.

CAUTION: Remove Batteries When Not in Use. As with any battery-powered instrumentation, batteries should be removed before short or long-term storage. Even with the new battery lid, batteries can leak, releasing toxic and corrosive battery acid and damaging equipment.

INSTALLING BATTERIES IN THE 6920V2-1 AND 6920V2-2 SONDES

To install the 8 AA-size alkaline batteries into the sonde, refer to the following directions and Figures 36 and 37.

Position the bail so that it is perpendicular to the sonde and use it as a lever to unscrew the battery cap by hand. Then slide the battery lid up and over the bulkhead connector.

Insert batteries, paying special attention to polarity. Labeling on the top of the sonde body describes the orientation.

2.3.4 STEP 4 - CONNECTING A FIELD CABLE

All YSI 6600V2-2, 6600EDS V2-2, 6600V2-4, 6920V2-1, 6920V2-2, 6820V2-2, 600XLM, 600QS, and 600 OMS V2-1sondes have a sonde-mounted cable connector for attachment of the field cable. Some versions of the 600R, 600XL, and 6820V2-1 sondes also have this connector.

However, some versions of the YSI 600R, 600XL, and 6820V2-1sondes have permanently attached

“integral” cables. If your sonde has a cable that is non-detachable, the next section will not be relevant.

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.

Figure 38

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.

For all of the sondes, the other end of the 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, realtime measurement, and uploading files.

This MS-8 connector also plugs directly into the 650 MDS display/logger. This instrument contains a microcomputer that allows it to be used in a similar manner to that of a terminal interface to a PC.

As an alternative to the field cable, 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.
