OPERATIONAL GUIDE INITIAL PREPARATION: The meter is supplied with four 1.5V AA alkaline batteries. Remove the battery cover on the back of the meter and insert the batteries while paying attention to their polarity. Attach the fluoride electrode (#3 on page 4), the reference electrode (#2) and the temperature probe (#1) to their respective connectors on top of the meter. Make sure that the electrodes are not touching the bottom of the beaker.
CALIBRATION In order to obtain accurate measurements, frequent calibration is recommended. For better results, calibrate at a temperature close to that of the solution to be tested (no more than ±3°C apart). The instrument can be calibrated at 1 or 2 points. Two-point calibration is always recommended for better accuracy. Calibration points can be chosen among 1 ppm fluoride, 2 ppm , 10 ppm, 100 ppm and 1000 ppm.
• Immerse the fluoride and reference electrodes at least 1 cm (½”) in the second calibration solution. Make sure that the electrodes are not touching the bottom of the beaker. Immerse the temperature probe close to the tip of the other electrodes. • The CON symbol appears to indicate that the second calibration solution has also been recognized and the reading is stable. Press CFM to confirm. • Calibration is now complete and the meter automatically returns to the normal operational mode.
PREPARATION The HI 4010 fluoride electrode is shipped dry. The HI 5313 reference electrode should be maintained wet with some storage solution in the protective cap. Remove the protective cap from the reference electrode. Any salt deposit around the electrode tip is normal and it will dissolve if rinsed with water. If the junction of the HI 5313 reference electrode is dry, soak the tip in HI 7082 solution for at least one hour prior to operation.
