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 the cuvette with 10 mL of

unreacted sample, up to the mark,

and replace the cap.

4• Place the cuvette into the cuvette

holder and ensure that the notch on

the cap is positioned securely into the

groove.

5• Press ZERO/CFM and the lamp, cuvette

and detector icons will appear on the

display, depending on the measurement

phase.

6• After a few seconds the display will

show “-0.0-”. The meter is now zeroed

and ready for measurement. Remove

the cuvette.

7• Fill one graduated mixing cylinder up

to the 25 mL mark with sample.

8• Add the content of one packet of

HI 93730A-0 Molybdenum reagent,

close the cylinder and invert it several

times until the powder is completly

dissolved. This is the blank.

9• Add the content of one packet of

HI 93730B-0 Reagent B to the

cylinder, close it and invert several

times until the powder is completely

dissolved.

10•Add the content of one packet of

HI 93730C-0 Reagent C to the

cylinder, close and shake it vigorously.

11•Fill a cuvette with 10 mL of the reacted

sample up to the 10 mL mark and

replace the cap.

12•Place the cuvette into the cuvette

holder and ensure that the notch on

the cap is positioned securely into the

groove.
