    OPERATIONAL GUIDE INITIAL PREPARATION Each meter is supplied complete with a 9V battery. Remove the battery compartment cover on the back of the meter and install the battery while observing its polarity. Connect the probe to the DIN socket on the top of the meter by aligning the pins with the socket and pushing in the plug.
  • Page 7 • Select the appropriate measurement range (EC or TDS). • Wait a couple of minutes for the temperature sensor to reach thermal equilibrium. The display will then show the measurement automatically temperature compensated for temperature with the appropriate indication among the following: “µS”...

  • Page 8: Ph Calibration

    pH CALIBRATION For greatest accuracy, frequent calibration of the instrument is recom- mended. The instrument should be recalibrated for pH: a) Whenever the electrode is replaced. b) At least once a month. c) After testing aggressive chemicals. d) Where extreme accuracy is required. PREPARATION Pour small quantities of pH7.01 (HI7007) or pH4.01 (HI7004) or pH10.01 (HI7010) solution into a clean beaker.
  • Page 9 Notes: • The probe should be submerged approximately 4 cm (1½”) into the solution. The thermometer has to be close to the probe. • If turning the knob the needed value can not be reached, clean the probe (see the “Probe Maintenance” section). If also after the probe cleaning the value can not be reached, replace the probe.

    pH VALUES AT VARIOUS TEMPERATURES For temperature compensation during calibration, please refer to the following chart. TEMP pH VALUES °C °F 4.01 6.86 7.01 9.18 10.01 4.01 6.98 7.13 9.46 10.32 4.00 6.95 7.10 9.39 10.24 4.00 6.92 7.07 9.33 10.18 4.00 6.90...

  • Page 11: Ec/Tds Calibration

    The TDS value in aqueous solutions is directly proportional to the con- ductivity. The ratio between the two parameters depends on the solution. HI9811-5 model has a fixed conversion factor set to 0.5. This means that 1 µS/cm is equal to 0.5 mg/L of TDS.

  • Page 12: Battery Replacement

    BATTERY REPLACEMENT The meters is powered by a 9V battery that is located on the rear of the instrument. When battery symbol is empty a low battery condition is indicated. When the low battery indication appears, only a few hours of working time remains.

  • Page 13: Probe Maintenance

    For better accuracy in measurements and to ensure a good performance of the probe, a frequent cleaning is recommended. For this purpose, soak it in Hanna Instruments HI700661 Cleaning Solution for 5 minutes. Notes: • For particular dirt (as for example protein, oil or grease) see the “Accessories”...
