Functional description:

1. Liquid Crystal Display.

2. Cuvet Holder with transparent protective

cup and alignment indicator.

3. ON/OFF key: to turn the meter on and

off.

4. ZERO key: press to zero the meter prior to

measurement.

5. READ/TIMER key: press for making a

measurement, or hold the key for 3

seconds to start a pre-programmed

countdown prior to measurement.

6. CAL CHECK key allows direct validation

with the exclusive Hanna CAL CHECK™

NIST traceable standards.

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 re-

placed. 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 mode

is entered. If

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.

Guide to display codes:

Measurement procedure:

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.

Measurement

“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 zero-

ing 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 concentra-

tion of the sample is beyond the programmed

range: dilute the sample and re-run the test.

A flashing value lower than the maximum concen-

tration indicates a low signal-to-noise ratio

condition. In this case accuracy of the result is not

guaranteed. Repeat the measurement procedure.
