Page 6: Operational Guide
OPERATIONAL GUIDE INITIAL PREPARATION The instrument is supplied complete with batteries. For placing the batteries inside the meter, see page 14. To prepare the instrument for use, connect the Fluoride and the reference electrodes to the input sockets on the top of the instrument. Connect the temperature probe to the temperature socket too. - Page 7 • Pour about 10-20 mL of the sample in a clean beaker and add the same quantity of HI 4010-00 (TISAB) solution to the beaker. Mix the solution for a few minutes. • Rinse the electrodes with deionized wa- ter and dry them attentively with a non-abrasive cloth.
- Page 8 TEMPERATURE MEASUREMENT The temperature can be measured independently from fluoride con- centration. • Immerse the temperature probe at least 1 cm (½”) in the prepared sample. • Wait for the reading to stabilize. The temperature of the solution will be shown on the lower part of the display.

Page 9: Calibration
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 in 1 or 2 points. Two-point calibration is always recommended for better accuracy. - Page 10 TWO-POINT CALIBRATION • Press CAL. The instrument will dis- play the measured Fluoride concentration on the primary LCD, if a previous calibration exists, or “10.0” standard on the secondary LCD, together with “CAL” and “Cal Point 1” tags. • If necessary, press the STD key to select a different standard value. •...

Page 11: Setup
Notes: • Press and hold Setup then Select before “CFM” tag appears, to toggle between standard and temperature display on secondary LCD line reading during calibration. • If the value measured by the instrument is not close to the selected standard, “WRONG” “ ” and “WRONG” “ ” tags will blink alternately. -

Page 15: Lcd Message Guide
The instrument is provided with the BEPS (Battery Error Prevention System) feature, which automatically turns the instrument off when the batteries level is too low to ensure reliable readings. At start up the display will show “0 bAtt” message for a few seconds, then the instrument automatically turns off. -
Page 16: Electrode Conditioning & Maintenance
ELECTRODE MAINTENANCE PREPARATION The HI 4010 fluoride electrode is shipped dry. The HI 5313 reference electrode should be main- tained 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. - Page 17 FLUORIDE ELECTRODE CLEANING General: Rinse the fluoride electrode with deionized water. Protein, oil & fat: Clean the electrode tip with a cotton wool soaked in alcohol, then rinse with deionized water. IMPORTANT: After cleaning, rinse the fluoride electrode thoroughly with deionized water and dry it attentively with a non- abrasive cloth.
