    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. The Model 3200 is compatible with YSI 3400 series conductivity cells when used with the YSI Model 3232 cell adapter.

    YSI 3200 series cells utilize a mini DIN connector that plugs directly into the 3200. If, however, you have a YSI 3400 series cell, the YSI 3232 cell adapter and a YSI 3220 or YSI 700 series temperature probe will be required. The YSI 3232 cell adapter mounts on the post on the rear of the 3200.
  • Page 10 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 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 937- 767-7241, and we'll be happy to help you.

    SECTION 3 SYSTEM CONFIGURATION AND OPERATION MENU The following section shows the software flow chart for the 3200. The two operating modes, Data and Operation, are shown at the top with the soft key functions that are accessed in each mode below them.

  • Page 16: Cell Calibration

    The cell constant of up to six different cells (# 0 - 5) can be stored in non-volatile memory. The 3200 can determine the cell constant for a cell at a single point or up to five points using different standard solutions.

  • Page 18: Cal K

    5. Using the [UP], [DOWN] and [DIGIT] soft keys, enter the value of the standard solution at the current temperature. Temperature compensation is OFF during cell calibration. Example: YSI 3161 Conductivity Calibrator is 1000uS at 25°C, but at 23°C you would enter 961uS.
  • Page 19 5. Using the [UP], [DOWN] and [DIGIT] soft keys, enter the value of the standard solution at the current temperature. Temperature compensation is OFF during cell calibration. Example: YSI 3161 Conductivity Calibrator is 1000uS at 25°C, but at 23°C you would enter 961uS.

  • Page 20: Temperature Compensation

    Offset When measuring conductance below 10uS (resistance above 100KΩ), the insulation resistance of the cell leads may be a source of error. This error may be greatly reduced by allowing the 3200 to calculate and store a zero offset value.

  • Page 21: Temp

    To calculate and store the linear temperature compensation coefficient: 1. Verify that the current configuration contains the correct cell constant for the current cell. 2. Clean the container and YSI 3200 Series cell (or YSI 3400 Series and temperature probe) with deionized water.
  • Page 22 To calculate and store the non-linear temperature compensation curve: 1. Verify that the current configuration contains the correct cell constant for the current cell. 2. Clean the container and YSI 3200 Series cell (or YSI 3400 Series and temperature probe) with deionized water.

  • Page 23: Platinization

    From the Cell Temp menu, the [SEND] soft key may be used to send the current temperature compensation data to a computer or serial printer via the RS232 port. PLATINIZATION The 3200 can be used to replatinize the electrodes of the cell. See section 6.2 Platinization for details. DISPLAY CONFIGURATION The 3200 display is extremely flexible.

  • Page 24: Measurement Units

    Selection of fields is important, even if only the large display is used, because, when a reading is stored in the 3200 memory, the date, time, temperature and conductivity are stored, along with the first two additional fields (fields other than date, time, temperature and conductivity) currently on the display.

  • Page 27: Ranging

    The Range menu allows the user to select between Auto and Manual ranging. The default is autoranging, where the 3200 will automatically select the range that displays the highest resolution for the sample being measured. Since this automatic selection takes time, the user may select manual ranging when measuring several samples that fall into the same range.

    Replatinizing The 3200 can be used to replatinize a cell that utilizes electrodes coated with platinum. See section 6.2 Platinization. You will need a 2-oz bottle of platinizing solution (YSI 3140). TEMPERATURE CORRECTION By convention, the conductivity of a solution is the conductivity it exhibits at 25°C.

    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.

  • Page 54: Salinity

    TEMPERATURE The Model 3200 system utilizes a thermistor of sintered metallic oxide that changes predictably in resistance with temperature variation. The algorithm for conversion of resistance to temperature is built-in to the Model 3200 software, and accurate temperature readings in degrees Celsius or Fahrenheit are provided automatically.

  • Page 55: Electrical-Noise Errors

    YSI 3200 series cells utilize a 4-wire connection virtually eliminating errors due to contact resistance. When using the YSI 3232 cell adapter to connect a 2-wire cell (such as the YSI 3400 series cells), contact resistance can be a source of error when measuring high conductivity. Lugs should be clean and free of mechanical distortion.
