Functional description:
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 re-
run the test.
Standard Low: The standard reading is less
than expected.
Standard High: The standard reading is higher
than expected.
Errors and warnings:
Measurement procedure:
5• Replace the cap to the cuvette, and shake
gently a couple of times.
6• Place the cuvette with the reacted deionized
water (blank) into the cuvette holder and
ensure that the notch on the cap is
positioned securely into the groove.
7• 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.
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 µ L
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.

ON SAMPLE READING:
DURING CALIBRATION PROCEDURE:
OTHER ERRORS AND WARNINGS:
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.

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.
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.
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 µ L
automatic pipette (see “Accessories”).
