SECTION 1 INTRODUCTION The Model 3200 is a microprocessor based; menu-driven instrument designed to perform laboratory measurement of conductivity, resistivity, salinity, total dissolved solids and temperature. The instrument’s menu system makes it simple to use. The new YSI 3200 series conductivity cells contain internal temperature sensors for temperature measurement and automatic temperature compensation.
Introduction 1.2 Section 1 USER FEATURES • Audio feedback • Soft key/menu system • Real time clock • Auto linear temperature compensation calibration Two temperature points are tested in a known solution to automatically determine the solution’s compensation slope. Alternatively, the user may input a temperature compensation factor directly (0 - 10%/°C).
Introduction 1.3 Section 1 CONTROLS FRONT PANEL The front panel of the instrument contains the display and keypad as shown below. 3200 CONDUCTIVITY INSTRUMENT OPERATION 1.372uS 12:40PM CELL Display 24.
Introduction Section 1 The 3200 has two main operating modes, Data and Operation. The current mode is displayed in the dark bar at the top right corner of the display. The following diagram shows the typical display while the instrument is in the Operation mode.

Introduction Section 1 REAR PANEL The rear panel contains the connections for the power supply, cell, external temperature probe and RS232 serial port. It also has a mounting post for the 3232 adapter as shown below. Adapter mounting post POWER SUPPLY CONNECTION The power supply connection requires a 12 VDC power supply (included) with at least 300 ma current. The polarity is marked on the instrument.
Introduction Section 1 temperature sensor. All YSI 3200 series cells contain an internal temperature sensor; therefore, an external temperature probe is NOT necessary when using a 3200 series cell. However, if an external temperature probe is used with a YSI 3200 series cell, the external temperature probe will override the temperature sensor in the cell.
SECTION 2 GETTING STARTED 2.1 UNPACKING When you unpack your new YSI Model 3200 for the first time, check the packing list to make sure you have received everything you should have. If there is anything missing or damaged, call the dealer from whom you purchased the Model 3200. If you do not know which of our authorized dealers sold the system to you, call YSI Customer Service at 800-765-4974 or 937767-7241, and we'll be happy to help you. 2.

Getting Started Section 2 3. Connect the Cell Plug the cell (YSI 3200 series) into the connector on the back of the instrument marked cell. NOTE: If you are using a YSI 3400 series cell, you will need the following: • 3232 adapter • YSI 3220 or 700 series temperature probe 4. Configure the 3200 Next, you must configure the 3200 with the correct cell constant of the cell you are using. From Operation mode, press the [CELL] soft key to enter the Cell menu.
Getting Started Section 2 5. Measurement After setting up the 3200 instrument and cell as described above, the following basic steps should be used to make measurements. 1. Immerse the cell (YSI 3200 series) in the solution to be measured. If using a YSI 3400 series cell, also place the temperature probe in the solution. 2. Gently tap the cell to remove any air bubbles and dip the cell in the solution 2 or 3 times to ensure proper wetting.

System Configuration and Operation 3.2 Section 3 CELL CALIBRATION Before operating the 3200, or whenever you change cells, you must configure the 3200 to match the cell used. There are two ways to do this. Choose the one that best meets your needs. 1. You may directly enter the manufacturer’s stated (or your manually calculated) cell constant (K). See 3.2 Cell Calibration, Configure. or 2. Allow the 3200 to calculate the cell constant and calibrate the system using standard conductivity solution(s).

SECTION 6 MAINTENANCE 6.1 CELL CLEANING AND STORAGE The single most important requirement for accurate and reproducible results in conductivity measurement is a clean cell. A dirty cell will change the conductivity of a solution by contaminating it. To clean a conductivity cell: 1. Dip or fill the cell with cleaning solution and agitate for two to three minutes. Any one of the foaming acid tile cleaners, such as Dow Chemical Bathroom Cleaner, will clean the cell adequately.
Maintenance Section 6 2. Use the [UP], [DOWN] and [DIGIT] soft keys to enter the platinization time required in minutes. Six minutes is usually sufficient for most electrodes. 3. Immerse the cell in the platinizing solution (YSI 3140). Make sure that both electrodes are submerged. 4. Press [ENTER] to start the platinization process. The following screen, showing the time remaining and the polarity of the polarization current, will be displayed. PLATINIZE 5.

SECTION 8 PRINCIPLES OF OPERATION 8.1 RATIOMETRIC CONDUCTIVITY The basic concept of microprocessor based ratiometric conductivity measurement is to place an unknown conductance and a known conductance in a series circuit with an AC voltage source, measure the voltage across each conductance and compute the value of the unknown. The object of conductivity measurement is to measure the resistive portion of the complex impedance of the cell.
Principles of Operation Section 8 Looking at our electrodes as sides of a cube, it becomes apparent that the conductance changes as the geometry of the cube changes. If the cube lengthens with respect to the area of the sides, then the conductance will decrease. If the area of the sides increases with respect to the distance between them, then the conductance will increase.
Principles of Operation Section 8 or less have larger electrodes that are closely-spaced. CHOOSING A CONDUCTIVITY CELL Decide which cell will be the most useful for your conditions by considering the conductivity of the solution you want to measure and the size of the sample. 3252, 3418 3256, 3255, 3446 3401 3440 3253, 3254, 0 0.1 1.0 10 100 1000 µS/cm 1 10 100 1000 mS/cm Conductivity The chart above reflects general guidelines.

Principles of Operation Section 8 CELL CONSTANT CALCULATION YSI 3200 and 3400 Series conductivity cells are calibrated to ± 1% of nominal by means of a YSI transfer standard traceable to OIML Recommendation 56 and NIST. Anytime the condition of the conductivity cell changes, it is possible that the cell constant has also changed. Therefore, you should calibrate your system regularly (See section 3.2 Cell Calibration, Cal K).

Principles of Operation Section 8 GENERAL CONDUCTIVITY MEASUREMENT PRECAUTIONS After selecting the proper cell, observe the following precautions to ensure accurate, repeatable results: 1. The cell must be clean before making any measurements. When working with substances having low conductivity, extraordinary cleanliness may be required. 2. Soak cells that have been stored dry in deionized water before use. 3. Immerse the cell in the solution deep enough to submerge the vent hole. 4.
Principles of Operation Section 8 temperature coefficient. In extreme cases, the temperature coefficient may have a value as high as 7%/°C. Each conductive ion has a different temperature coefficient. When practical, control the temperature of the solution to be analyzed. For high precision work (±1%), maintain the temperature at 25°C ± 0.1°C. For routine lab work, 25°C ± 0.5°C may be acceptable.
Principles of Operation Section 8 SMALL SAMPLE MEASUREMENTS It is not always possible to immerse the conductivity cell in a solution for measurements. If the quantity of solution is not sufficient for a proper measurement with a dip cell, a sample must be removed for assay. For this application, use the 3254 fill cell. This cell requires 5 ml of sample. Alternatively, any 3200 or 3400 Series cell, except the 3418, may be inverted and used as a fill cell.
Principles of Operation 8.3 Section 8 SALINITY Salinity is determined automatically from the Model 3200 conductivity and temperature readings according to algorithms found in Standard Methods for the Examination of Water and Wastewater (ed. 1995). The use of the Practical Salinity Scale 1978 results in values which are unitless, since the measurements are carried out in reference to the conductivity of standard seawater at 15°C.
Principles of Operation Section 8 ELECTRICAL-NOISE ERRORS Electrical noise can be a problem in any measurement range, but will contribute the most error and be the most difficult to eliminate when using the lowest conductance settings. The noise may be either line-conducted or radiated or both, and may require revised lead dress, grounding, shielding, or all three. Often, all that is necessary is to make sure that parallel leads are of equal length and twisted together.
