Dear Customer,

Thank you for choosing a Hanna product. This manual will provide you

with the necessary information for the correct use of the instrument. Please

read it carefully before using the meter. If you need additional technical

information, do not hesitate to e-mail us at [email protected].

Functional description:

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.

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:

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 unreacted

sample, up to the mark and replace the

cap.

4• Add 6 drops of HI 93705A molybdate

reagent. Replace the cap and swirl the

solution.

5• Wait for 4 minutes, add the content of

one packet of HI 93705B citric acid reagent

and shake until it is completly dissolved.

6• Wait for 1 minute. This is the blank.

7• Place the cuvette into the cuvette holder

and ensure that the notch on the cap is

positioned securely into the groove.

8• Press ZERO/CFM and the lamp, cuvette

and detector icons will appear on the display,

depending on the measurement phase.

9• After a few seconds the display will show

“-0.0-”. The meter is now zeroed and

ready for measurement. Remove the cuvette.

10•Add one packet of the HI 93705C amino

acid reagent and shake until it has

dissolved.

11•Replace the cuvette into the holder and

ensure that the notch on the cap is

positioned securely into the groove.

12•Press and hold READ/ /TIMER for three

seconds and the display will show the

countdown prior to measurement or

alternatively wait for 3 minute and press

READ/ /TIMER. An audible “beep”

indicates the end of countdown period. In

all cases the lamp, cuvette and detector

icons will appear on the display, depending

on the measurement phase.
