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.
