Guide to display codes:

This prompt appears for 1 second each time the instrument is turned on.

The parameter code “747” indicates that the meter is in a ready state and zeroing can be performed.

Sampling In Progress. Flashing “SIP” prompt appears each time the meter is performing a measurement.

“-0.0-”, the meter is in a zeroed state and measurement can be performed.

“CAP”, Light over range: the cuvet is not inserted correctly and an excess ambient light is reaching the detector. If the cover is properly installed, then contact your dealer or the nearest Hanna Customer Service Center.

The blinking “BAT” indicates that the battery voltage is getting low and the battery needs to be replaced.

“-bA-”, the battery is dead and must be replaced. Once this indication is displayed, the meter will lock up. Change the battery and restart.

“Conf”, the meter has lost its configuration. Contact your dealer or the nearest Hanna Customer Service Center.

CALIBRATION MODE MESSAGES

The date of the last calibration appears on the LCD each time the calibration is performed for the first time, “F.CAL” appears.

“F.CAL” indicates that the factory calibration is selected.

The flashing digits indicate that:

1. the month can be set

2. the day can be set “Stor”, appears for 1 second at the end of the

calibration procedure, to indicate that the calibration data has been stored.

“Error”, the concentration of the calibration solution used is not correct. Repeat the calibration procedure with the right standard solution, and verify it is not expired. If the calibration procedure fails again, contact your dealer or the nearest Hanna Customer Service Center.

ERROR MESSAGES

On zero reading

Blinking “-0.0-” indicates that the zeroing procedure failed due to a low signal-to-noise ratio. In this case press ZERO again.

“no L”, the instrument cannot adjust the light level. Please check that the sample does not contain any debris.

calibration mode

is entered. If

“L Lo”, there is not enough light to perform a measurement. Please check the preparation of the zero cuvet.

“L Hi”, there is too much light to perform a measurement. Please check the preparation of the zero cuvet.

On sample reading

“-SA-”, there is too much light for the sample measurement. Please check if the right sample cuvet is inserted.

“Inv”, the sample and the zero cuvet are inverted. “ZErO”, a zero reading was not taken. Follow the

instruction in the measurement procedure for zeroing the meter.

Under range. A blinking “0.000” indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure you use the same cuvet for reference (zero) and measurement.

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.

A flashing value lower than the maximum concentration indicates a low signal-to-noise ratio condition. In this case accuracy of the result is not guaranteed. Repeat the measurement procedure.

Measurement procedure:

Measurement

1• Turn the meter on by pressing ON/OFF. 2• When the LCD displays “747”, it is ready. 3• Fill the cuvet with 10 mL of unreacted

sample, up to the mark, and replace the cap.

4• Place the cuvet into the holder and ensure

that the notch on the cap is positioned securely into the groove.

5• Press ZERO and “SIP” will blink on the

display.

6• After a few seconds the display will show

“-0.0-”. The meter is now zeroed and ready for measurement.

7• Remove the cuvet and add the content of

one packet of HI 95747-0 Copper Low Range reagent.

8• Replace the cap and shake gently for 15

seconds.

9• Replace the cuvet into the holder and ensure

that the notch on the cap is positioned securely into the groove.

10•Hold READ/TIMER for three seconds. The

display will show the countdown prior to measurement. Alternatively, wait for 45 seconds and just press READ/TIMER.

In both cases “SIP” will blink during measurement.

11•The instrument directly displays concentration

in mg/L of copper on the Liquid Crystal Display.

INTERFERENCES

• Cyanide

• Silver

• For strongly buffered alkaline or acidic samples, pH should be adjusted between 6 and 8 before addition of reagent.

• To avoid interferences due to fingerprints, oil or dirt it is very important that the cuvet is wiped clean prior to insertion in the cuvet holder. Replacement of scratched cuvets is strongly recommended.

Validation and Calibration procedures

Warning: do not validate or calibrate the instrument with standard solutions other than the Hanna CAL CHECK™ Standards, otherwise erroneous results will be obtained. For accurate validation and calibration results, please perform tests at room temperature (18 to 25°C; 64.5 to 77.0°F).

Use the optional CAL CHECK™ cuvets (see “Accessories”) to validate or calibrate instruments.

VALIDATION

1• Turn the meter on by pressing ON/OFF. 2• When the LCD displays “747”, it is ready. 3• Place the CAL CHECK™ Standard Cuvet A

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

4• Press ZERO and “SIP” will blink on the

display.

5• After a few seconds the display will show

“-0.0-”. The meter is now zeroed and ready for validation.

6• Remove the cuvet. 7• Place the CAL CHECK™ Standard

HI 95747-11 Cuvet B into the holder and ensure that the notch on the cap is positioned securely into the groove.

8• Press CAL CHECK key and “SIP” will blink

during measurement.

9• Wait for a few seconds and the display will

show the validation standard value.

Validation

The reading should be within specifications as reported on the CAL CHECK™ Standard Certificate. If the value is found out of specifications, please check that the cuvets are free of fingerprints, oil or dirt and repeat validation. If results are still found out of specifications then recalibrate the instrument.

CALIBRATION

Note: It is possible to interrupt the calibration

procedure at any time by pressing ON/OFF.

64.5 to 77.0°F).

1• Turn the meter on by pressing ON/OFF. 2• When the LCD displays “747”, it is ready. 3• Enter the calibration mode by holding CAL

CHECK key for three seconds.

4• The date of the last calibration appears (e.g.:

month “01”, day “08”). “F.CAL” means that the factory calibration is selected.

Note: at this point it is possible to reset the

instrument to restore FACTORY CALIBRATION

5• Place the CAL CHECK™ Standard Cuvet A

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

6• Press ZERO and “SIP” will blink on the

display.

7• After a few seconds the display will show

“-0.0-”. The meter is now zeroed and ready for calibration.

8• Remove the cuvet. 9• Place the CAL CHECK™ Standard

HI 95747-11 Cuvet B into the holder and ensure that the notch on the cap is positioned securely into the groove.

10•Press READ/TIMER and “SIP” will blink on the

display.

11•The instrument will show for three seconds the

CAL CHECK™ standard value.

Then the date of last calibration (e.g.: “01.08”) appears on the display, or “01.01” if the factory calibration was selected. In both cases the number of the month is blinking, ready for date input.

Note: if display will show “ERR” the calibration

procedure failed. Verify that the right CAL CHECK™ Standard Cuvet B is inserted, that both A and B cuvets are free from fingerprints or dirt and that they are inserted correctly.

Calibration

12•Keep READ/TIMER pressed to scroll to the

desired month number (01-12).

13•When the correct month has been set, press

ZERO to confirm. Now the display will show the day number blinking. Keep READ/TIMER pressed to scroll to the desired day number (01-31).

Note: it is possible to change from

day

month

and vice versa by pressing ZERO.

14•When both the day and month have been

selected, hold CAL CHECK key for three seconds to store date and calibration values. The instrument will show for one second “Stor”, to confirm that the new calibration data has been accepted.

15•The instrument will return automatically to

the measurement mode by displaying the parameter code (“747”) on the LCD.
