  • Page 38: Operational Guide

    OPERATIONAL GUIDE The setting of the various keys are made via the front panel keys and trimmers. When each key is pressed the LED is lighted indi- cating to the user that the function is in operation. Make sure that the pH or the ORP meter with the electrode is calibrated before operat- ing the instruments (see page 40-42).
  • Page 39 Use a small screwdriver to adjust the trim- mers "ACID SET"/"COARSE" and "FINE" un- til the desired base set value is displayed. ACID BASE COARSE ACID SET FINE To set the working point of base dosage, press the "BASE SET" key. The display will show the set value for base dosage.
  • Page 40 Use a small screwdriver to adjust the trim- mers "∆AL" until the desired tolerance is displayed. ∆AL ∆AL For example: in HI 8710 if the set value is pH 3 and a ∆ Alarm of 1.5 pH is chosen, the instrument gives an alarm every time the measured pH value is higher than 4.5 pH or lower than 1.5 pH.

  • Page 43 Note: to get accurate readings, use pH 4.01 if you are going to measure acid samples or pH 10.01 for alkaline mea- surements. Shake briefly and wait one minute before adjusting the slope trimmer to display pH4.01 (or 10.01) on the LCD if the temperature of the buffer solution is at 25°C, if not refer to the chart on page 43 for appropriate buffer value for the corresponding temperature.

  • Page 44: Orp Calibration

    ORP CALIBRATION Make sure you are in the mea- surement mode (MEASURE SURE COARSE LED light is on) and not in the FINE set mode before proceeding with the calibration (not for HI 8512). Immerse the electrode in HI 7020 ORP solution. HI 7020 Adjust the slope trimmer until an ORP value of between 200 mV and 250 mV is displayed.

  • Page 50: Taking Redox Measurements

    TAKING REDOX MEASUREMENTS Redox measurements allow the quantifica- tion of the oxidizing or reducing power of a solution, and are commonly expressed in Oxidation may be defined as the process during which a molecule (or an ion) loses electrons and reduction as the process by which electrons are gained.
  • Page 51 To make correct redox measurements the following conditions must prevail: The surface of the electrode must be cleaned and smooth. The surface of the electrode must un- dergo a preventive treatment depending on the solution to be measured has oxidizing or reductive characteristics. Because the Pt/PtO system depends on the pH, the pretreatment of the electrode may be determined by the pH and the redox potential...
  • Page 52 In the event that measurements are performed with solutions containing sulfides or proteins, the cleaning of the diaphragm of the refer- ence electrode must be performed (see page 20, "Cleaning Procedure").

  • Page 55 Follow the Preparation Procedure above be- fore taking measurements. Note: NEVER STORE THE ELECTRODE IN DISTILLED WATER OR DRY. PERIODIC MAINTENANCE Inspect the electrode and the cable. The cable used for the connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the elec- trode stem or bulb.
  • Page 56 IMPORTANT: After performing any of the cleaning procedures rinse the electrode thor- oughly with distilled water, drain and refill the reference chamber with fresh electrolyte, (not necessary for GEL filled electrodes) and soak the electrode in HI 70300 or HI 80300 Stor- age Solution for at least 1 hour before taking measurements.
