    Connect the Handheld to the Cable Assembly The cable connectors are keyed for positive mating and to prevent connector damage (Figure 3). The handheld retains its IP-67 waterproof rating when the cable is disconnected. However, the connectors are not wet-mateable and should be clean and dry before connecting.

  • Page 7: Sensor Installation/Removal

    Sensor Installation/Removal Probe assemblies like the ODO/CT, ODO/T, and ProOBOD feature integral sensors. These sensors cannot be removed from the cable. Therefore, this section pertains only to the ProDSS 4-port cable. ProDSS 4-port Cable ProDSS 4-port cables feature user-replaceable sensors. The ports on the bulkhead are universal, meaning that you can install any sensor into any port.

Use the sensor installation/removal tool to tighten the retaining nut clockwise until snug, about a ¼ to ½ additional turn of the retaining nut. Be careful not to over-tighten the retaining nut. NOTICE: Incorrect installation or over-tightening can cause damage to the sensor or bulkhead that is not covered by the warranty.

Calibration value: This is the value the sensor will be calibrated to. The Yellow Line on the graph corresponds to this value. Accept Calibration: Select this to calibrate the sensor to the calibration value.

  • Page 32: Depth

    Calibration in the atmosphere “zeros” the sensor with respect to the local barometric pressure. YSI recommends calibrating depth at the location of measurement. A change in barometric pressure will result in a zero shift unless the transducer is recalibrated to the new pressure.

  • Page 33: 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.

NOTE: If the data is not stabilized after 40 seconds, gently rotate the sensor or remove/reinstall the calibration cup to make sure that no air bubbles are in the conductivity cell.

  • Page 35: Dissolved Oxygen

    Dissolved Oxygen ODO calibration requires the current “true” barometric pressure. Make sure that the barometer is reading accurately prior to ODO calibration. Calibrating in DO% or DO% local automatically calibrates the mg/L and ppm measurement. There is no reason to cali- brate both parameters.
  • Page 36 ODO mg/L Calibration 1. Place the ODO and conductivity/temperature sensor into a water sample that has been titrated by the Winkler method to determine the dissolved oxygen concentration in mg/L. 2. Push the key, then select ODO. Select DO mg/L. 3.

  • Page 38 Turbidity Calibration 2-Point Turbidity calibrations, more than most other paramters, are susceptible to interference from contamination. It is critical for calibrations to be performed with very clean sensors, guards, and cups. NOTE: Calibration standards should not be re-used. 1. Fill the calibration cup to the appropriate level with 0 FNU standard (deionized water may be used as a substitute).

    (PE). TAL-PE sensors are typically selected for monitoring marine cyanobacteria. TAL Units The TAL sensors report data in RFU and g/L of pigment (Chl, PC or PE) units. YSI recommends reporting in Relative Fluorescence Units (RFU). RFU is used to set sensor output relative to a stable secondary standard, Rhodamine WT dye. This allows users to calibrate sensors identically so that results from sensor to sensor can be compared.
  • Page 40 Rhodamine WT Dye Solution Preparation Rhodamine WT dye solution must be used when completing a 2-point calibration. Purchase Rhodamine WT as a 2.5% solution to follow the procedure below. Kingscote Chemicals (Miamisburg, OH, 1-800-394-0678) has historically had a 2.5% solution (item #106023) that works well with this procedure. Note that there are many types of Rhodamine—make sure Rhodamine WT is selected.

  • Page 42 PE, PC and Chlorophyll Calibration 2-Point Each channel of the sensor must be calibrated independently. Calibration of the chlorophyll channel does not set the calibration for the PC channel or the PE channel. In addition, calibrating in RFU for a channel does not automatically calibrate the µg/L measurement for the same channel.
  • Page 43 pH/ORP 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. In pH4 buffer, the mV reading should be 165 to 185 mV higher than the reading in pH 7 buffer.
