Absolute EC Resolution Unit (HI98194, HI98195 only) Absolute conductivity displays the conductivity without temperature compensation. See EC resolution for resolution details.

  • Page 28: Parameter Coefficients

    EC Reference Temperature (HI98194, HI98195 only) This value is used for temperature compensated conductivity. All EC measurements will be referenced to the conductivity of a sample at this temperature. Press the softkey to select the desired option; 20 °C or at 25 °C. The default value is 25 °C.

  • Page 29: Calibration Mode

    This value should be kept low if you want a fast response. Press Modify to select the desired number of samples to average. This value can be set from 1 to 20 samples. The default value is 1. Note: Each reading takes 1 second, so when logging the first sample will be delayed by a few seconds if averaging is used.

  • Page 30: Quick Calibration

    The quick calibration method provides a quick single point calibration for pH, conductivity and dissolved oxygen sensors. HI9828‑0 calibration solution is used for both pH and conductivity. • Fill the calibration beaker 2/3 full with HI9828‑0 calibration solution. • Slowly place the sensors into the solution and dislodge bubbles that may adhere to the sensors. •...

If the meter does not accept a pH calibration point, a short message is displayed to indicate the possible error source. The following screens are examples: These are the available messages: •...

  • Page 34: Relative Mv Calibration

    The “ORP calibration” allows the user to perform a single point custom calibration (relative mV) or to restore the factory calibration. The Oxidation‑Reduction Potential (ORP), displayed in mV, is the voltage that results from the difference in potential between the platinum ORP sensor and the silver/silver chloride reference electrode.

  • Page 35: Dissolved Oxygen Calibration (Hi98194, Hi98196 Only)

    • To restore the factory calibration data, select the corresponding option in the “ORP calibration” menu and then press Select. DISSOLVED OXYGEN CALIBRATION (HI98194, HI98196 only) The accuracy of dissolved oxygen measurements is directly related to membrane cleanliness and calibration technique. Oily coating and biological contaminants are the primary cause of calibration drift in dissolved oxygen sensors.
  • Page 36 The calibration of the D.O. concentration range can only be performed at a single custom point (4 to 50 mg/L). It is recommended to calibrate the D.O. sensor close to the values that will be measured. Choose “DO calibration” from the “Calibration” menu, select the D.O. calibration type using the / keys and press Select to confirm.
  • Page 37 • Press ESC twice to return to the main menu. • Press Measure to return to the measurement screen. D.O. concentration (HI98194, HI98196 only) Verify the barometric pressure, conductivity and temperature reading are correct. Calibrate them if necessary. To calibrate the D.O.

  • Page 38: Conductivity Calibration (Hi98194, Hi98195 Only)

    A conductivity calibration is used to adjust for variations in cell factors by using a standard solution of known conductivity. Oily coating and biological contaminants are the primary cause of calibration drift in conductivity sensors. This type of fouling changes the apparent cell geometry, resulting in a shift in cell constant. Before performing a conductivity calibration inspect the EC sensor for debris or blockages.
  • Page 39 • Immerse the sensor into the rinse standard by raising and lowering the beaker a few times to ensure that the EC sensor channels are filled with fresh standard. • Place the calibration beaker over the EC sensor and dislodge any trapped bubbles. Screw the beaker into place.
  • Page 40 • Place the calibration beaker over the EC sensor and dislodge any trapped bubbles. Screw the beaker into place. Wait for the reading to stabilize. The stability timer will count down and Confirm will appear. • Note the temperature and adjust the conductivity value if needed. •...

  • Page 41: Temperature Calibration

    Notes: These procedures calibrate the slope value. To calibrate the offset, set the calibration point at 0 μS/cm and repeat the procedure. If the temperature input is not within the acceptable range (0 to 50 °C), the message “Invalid temperature” is displayed.

  • Page 42: Atmospheric Pressure Calibration

    Place HI9819X in a wind‑free area and choose “Custom pressure” to perform a user calibration or “Restore factory calib”. Note: “Custom pressure” procedure requires a reference barometer. Select the “Atm. pressure” from the “Calibration” menu. • Select the “Custom pressure” option. •...
