Errors and warnings:

ON ZERO READING:

Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette.

Light Low: There is not enough light to perform a measurement. Please check the preparation of the zero cuvette.

No Light:The instrument cannot adjust the light level. Please check that the sample does not contain any debris.

ON SAMPLE READING:

Inverted cuvettes: The sample and the zero cuvette are inverted.

Zero: A zero reading was not taken. Follow the instructions of the measurement procedure for zeroing the meter.

Under range: A blinking “0.00” indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure you use the same cuvette for reference (zero) and measurement.

Over Range: A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and rerun the test.

DURING CALIBRATION PROCEDURE:

Standard Low: The standard reading is less than expected.

Standard High: The standard reading is higher than expected.

OTHER ERRORS AND WARNINGS:

Cap error: Appears when external light enters in the analysis cell. Assure that the cuvette cap is present.

Cooling lamp: The instrument waits for the lamp to cool down.

Battery low: The battery must be replaced soon.

Dead battery: This indicates that the battery is dead and must be replaced. Once this indication is displayed, the meter will lock up. Change the battery and restart the meter.

Measurement procedure:

Measurement

1• Turn the meter on by pressing ON/OFF. 2• When the beeper sounds briefly and the

LCD displays dashes, the meter is ready. The blinking “ZERO” indicates that the instrument needs to be zeroed first.

3• Fill one cuvette with 10 mL of deionized

water. For most accurate results, use of a class A laboratory pipette is strongly recommended. Alternatively, fill the cuvette up to the 10 mL mark.

4• Add 2 mL of HI 93729-0 Fluoride Reagent

to the cuvette by use of the 2000 µL

automatic pipette (see “Accessories”).

8• Press ZERO/CFM and the lamp, cuvette

and detector icons will appear on the display, depending on the measurement phase. Wait for a few seconds and the display will show "-0.0-". Now the meter is zeroed and ready for measurement.

9• Remove the blank from the instrument. 10•Remove the cap from the cuvette and

discard the blank.

11•Rinse the cuvette a couple of times with

the unreacted sample and discard it. Turn upside down the empty cuvette and

shake it to remove excess of liquid.

12•Fill the same cuvette with 10 mL of

unreacted sample. For most accurate results, use of another clean class A laboratory pipette is strongly recommended (see “Accessories”). Alternatively, fill the cuvette up to the 10 mL mark.

13•Add 2 mL of HI 93729-0 Fluoride Reagent

to the cuvette by use of the 2000 µL

automatic pipette.

14•Replace the cap to the cuvette, and shake

gently a couple of times.

15• Place the cuvette with the reacted sample into

the cuvette holder and ensure that the notch on the cap is positioned securely into the groove.

16•Press and hold READ/ /TIMER for three

seconds. The display will show the countdown prior to measurement. The beeper is playing a beep at the end of countdown period.

Alternatively, wait for two minutes and just press READ/ /TIMER. In both cases, the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase.

17•The instrument directly displays concentration

in mg/L (ppm) of fluoride on the LCD.

Note: For wastewater or seawater samples, be-

fore performing measurements, distillation is required.

INTERFERENCES

• Chlorine interferes at all levels: to eliminate Cl interference add to the 10 mL unreacted sample, 1 drops of the optional HI 93703-53 Chlorine Remover, for each 2 mg/L of chlorine.

• Positive error: Chloride above 7000 mg/L; Phosphate, ortho above 16 mg/L; Sodium hexametaphosphate above 1.0 mg/L; Sulfate above 200 mg/L

• Negative error: Alkalinity (as CaCO3) above 5000 mg/L; Aluminum above 0.1 mg/L; Iron, ferric above 10 mg/L
