PREPARATION PROCEDURE 1. Remove the protective cap. Do not be alarmed if salt deposits are present, this is normal. Rinse the electrode with water.

  • Page 26: Storage Procedure

    For a faster response and to avoid cross-contamination of the samples, before taking measurements, rinse the electrode tip with a few drops of the solution to be tested. 11.2. STORAGE PROCEDURE To ensure a quick response, the glass bulb and the junction should be kept moist and not allowed to dry.

    5. Press the CAL or ESC key to save the current calibration. 6. To continue calibrating with additional buffers, rinse and submerse the electrode approximately 4 cm (1½”) into the next buffer solution and stir gently. Follow the procedure above to add the buffer to the calibration.

  • Page 30: Ph Measurement Messages & Warnings

    For improved accuracy, calibration of the instrument is recommended (see pH CALIBRATION section details). When not in use, add a few drops of Storage solution to the protective cap to keep the electrode hydrated. Ensure the electrode is rinsed thoroughly with the sample to be measured before use. As pH readings are directly affected by temperature, it is recommended to allow the sample and the pH electrode to reach thermal equilibrum.

    After the electrode has been cleaned, perform a new calibration. Note: If the calibration data is cleared, the comparison is done with the default values. 12.4. TEMPERATURE MEASUREMENTS HI98169 the temperature sensor is integrated in the FC10483 probe. Note: The temperature can be displayed in Celsius degrees ( ° C) or in Fahrenheit degrees ( ° F)

    13. mV 13.1. mV MEASUREMENT Submerge the electrode tip (4 cm/1½”) into the sample to be tested and wait a few seconds for the reading to stabilize. mV measurements are generated by the pH electrode and are displayed with 0.1 mV resolution.

  • Page 33: Mv Measurement Messages & Warnings

    13.4. mV MEASUREMENT MESSAGES & WARNINGS Wrong Relative Offset The absolute mV reading is out of range or the relative mV offset is out of the offset window. Change the input value or the relative mV value to complete the calibration process.

  • Page 34: Mv & Temperature Calibration (For Technical Personnel Only)

    All instruments are factory calibrated. Calibration is only required if the temperature or mV measurements are inaccurate. Recalibration should only be performed by technical personnel. Contact your local Hanna Instruments Office or follow the instructions below to recalibrate the instrument.

  • Page 35: Mv Calibration

    Notes: The “WRONG” tag will blink if the reading is not within the range of the selected calibration point. Verify calibration condition or contact your local Hanna Instruments Office if you cannot calibrate. Press CAL (or ESC) key to return to measurement mode.
