  • Page 34: Taking Measurements

    Operation Taking measurements For the highest accuracy, calibrate the instrument before taking measurements (Calibration on page 33). 1. Create site and Data ID lists for logged data (if applicable) (Logging on page 19). 2. Set the logging method (single or interval) (Logging on page 19).

  • Page 35: Calibration

    Calibration ProDSS sensors (except temperature) require periodic calibration to maintain accurate measurements. Calibration procedures follow the same basic steps with variations for specific parameters. Before calibration • Enter GLP user-defined data if applicable to user requirements (User ID, Probe ID, User Field #1/2) (GLP menu on page 17).
  • Page 36 Calibration Alternately, pH, ORP, and conductivity calibrations can be completed in a beaker or other container using the same basic procedure described above. Make sure that the temperature sensor and the sensor to be calibrated are completely submerged. When submerging the conductivity sensor, make sure that the calibration solution covers the vent hole on the side of the conductivity sensor and there is at least 25.4 mm (1 in) distance between the sides and bottom of the calibration container and the conductivity probe.

  • Page 37: Conductivity

    (nLF) conductivity, TDS, resistivity, and density. Calibration is only available for specific conductance, conductivity, and salinity. Calibrating one of these options automatically calibrates the other conductivity/temperature parameters listed above. For both ease of use and accuracy, YSI recommends calibrating specific conductance.

  • Page 38: Barometer

    NOTE: If you get calibration error messages, check for proper sensor immersion, verify the calibration solutions is fresh, the correct value has been entered into the ProDSS, and/or try cleaning the sensor. 9. Rinse the bulkhead and sensors in clean water then dry.

  • Page 39: Dissolved Oxygen

    Calibration Dissolved oxygen ODO calibration requires the current “true” barometric pressure. Make sure that the barometer is reading accurately and recalibrate the barometer as necessary. ODO% and ODO% local - water saturated air calibration NOTE: This method calibrates the instrument’s DO% measurement or DO% Local measurement if DO% local is enabled in the sensor setup menu.

  • Page 41: Ph/Orp

    Calibration pH/ORP pH calibration 1-point NOTE: If performing a 1-point calibration, use buffer 7 (6.86) as your calibration point for highest accuracy. NOTE: Observe the pH mV readings during calibration to understand the condition and response of the pH sensor. In buffer 7, pH mVs should be between -50 and +50.

  • Page 43: Depth

    Calibration Depth NOTE: This calibration option is available only if your bulkhead is equipped with a depth sensor. The depth sensor is located where the cable connects to the bulkhead (Figure 59 on page 54). For the calibration, make sure that the depth sensor is clean and in air, not immersed in any solution. For highest accuracy, keep the bulkhead still and in one position while calibrating.

  • Page 46: Ises: Ammonium, Nitrate, & Chloride

    Calibration ISEs: Ammonium, Nitrate, & Chloride Before performing the calibration, review Calibration setup (pH, ORP, ISE, conductivity, turbidity) on page The ISE sensors can be calibrated to one, two or three points. A 2-point calibration without chilling a third calibration solution is extremely accurate and is the preferred method.
  • Page 47 Calibration ISE calibration 3-point 1. Perform the Calibration setup (pH, ORP, ISE, conductivity, turbidity) on page 2. Fill the calibration cup to fill line one with standard #1 (approximately 170 mLs). 3. Push the key, then select the applicable ISE sensor. 4.
  • Page 48 Calibration Chilled third calibration point The 3-point calibration method assures maximum accuracy when the temperature of the media to be monitored cannot be anticipated. If you must perform a chilled 3-point calibration, the following procedure requires one portion of the high concentration calibration solution and two portions of the low concentration calibration solution. The high concentration solution and one of the low concentration solutions should be at ambient temperature.
  • Page 49 The following recipes are provided for preparation of 10 and 1000 mg/L chloride reagents. Nitrate and Ammonium standards can be purchased from YSI or other laboratory supply companies. WARNING: Some of the chemicals required for these solutions could be hazardous under some conditions. It is the responsibility of the user to obtain and study the MSDS for each chemical and to follow the required instructions with regard to handling and disposal of these chemicals.
  • Page 50 Calibration Preparing nitrate standards We recommend using YSI calibration solutions whenever possible. However, qualified users can save cost by following these recipes for 1 and 100 mg/L nitrate standards. Other concentrations can be made by altering the amount of potassium nitrate. All other concentrations should remain unchanged.
  • Page 51 Calibration Preparing ammonium standards We recommend using YSI calibration solutions whenever possible. However, qualified users can save cost by following these recipes for 1 and 100 mg/L standards. Other concentrations can be made by altering the amount of ammonium chloride. All other ingredient concentrations should remain unchanged.

Figure 64 Conductivity/Temperature Long-term storage Dissolved oxygen sensor ODO sensor caps are warranted for 1 year but have a typical working life of 18 to 24 months. As the ODO sensor caps ages, large scratches in the paint/dye layer and changes in the dye layer can reduce measurement stability and response time.
  • Page 60 Maintenance and storage ODO sensor cap replacement (continued) 1. Turn the used sensor cap counterclockwise to remove it from the sensor. NOTE: If possible, do not use a tool to remove the cap from the sensor. If necessary, carefully turn the cap counterclockwise with pliers until it breaks loose.
