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].
1. RANGE/GLP/ key: press to change the paramter, press and hold
for three seconds to enter GLP mode. In calibration mode press to edit
the date and time.
2. CAL CHECK key: press to perform the validation of the meter, or
press and hold for three seconds to enter calibration mode.
3. ZERO/CFM key: press to zero the meter prior to measurement, to
confirm edited values or to confirm factory calibration restore.
4. READ/ /TIMER key: In measurement mode, press to make a
measurement, or press and hold for three seconds to start a
pre-programmed countdown prior to measurement. In
GLP mode
press to view the next screen.
5. ON/OFF key: to turn the meter on and off.
6. Liquid Crystal Display (LCD)
7. Cuvette alignment indicator
8. Cuvette holder
DISPLAY ELEMENTS DESCRIPTION:
Functional description:
1. The measuring scheme (lamp, cuvette, detector), appears during
different phases of zero or reading measurement
2. Error messages and warnings
3. The battery icon indicates the charge state of the battery
4. The hourglass appears when an internal check is in progress
5. Status messages
6. The chronometer appears when the reaction timer is running
7. The month, day and date icons appear when a date is displayed
8. Four digit main display
9. Measuring units
10. Four digit secondary display
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.
Errors and warnings:
ON ZERO READING:
ON SAMPLE READING:
DURING CALIBRATION PROCEDURE:
OTHER ERRORS AND WARNINGS:
Cap error: Appears when external light enters
in the analysis cell. Assure that the cuvette cap
is present.
Cooling lamp: The instrument waits for the
lamp to cool down.
Standard Low: The standard reading is less
than expected.
Standard High: The standard reading is higher
than expected.
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” 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.
1• Turn the meter on by pressing ON/OFF.
2• When the beeper sounds briefly and the LCD
displays dashes and “P1” (Calcium) and
“P2” (Magnesium) the meter is ready. The
code that appears on the secondary display is
the one of the last selected parameter. If
necessary, press RANGE/GLP/ to change
parameter. The blinking “ZERO” indicates
that the instrument needs to be zeroed first.
3• Calcium: Using a 5 mL syringe add exactly
3 mL of sample to the cuvette. Use the
pipette to fill the cuvette up to the 10 mL
mark with the HI 93752A-0 Ca Buffer
Reagent. Add 4 drops of Buffer Reagent.
Magnesium: Using a 1 mL syringe add
exactly 1 mL of HI 93752A-0 Mg Buffer
Reagent. Use the pipette to fill the cuvette
up to the 10 mL mark with the HI 93752B-0
Mg
Indicator Reagent. Replace the cap
and invert several times to mix.
4• Place the cuvette into the 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.
7• Remove the cuvette.
8• Calcium: Using a 1 mL syringe add exactly
1 mL of the HI 93752B-0 Ca Oxalate reagent.
Magnesium: Using another 1 mL syringe,
add to the cuvette exactly 0.5 mL of sample.
Note
: Do not mix up the two 1 mL syringes!
9• Calcium: Replace the cap and invert the
cuvette 10 times to mix.
Magnesium: Replace the cap and invert
several times to mix.
10•Replace the cuvette into the holder and
ensure that the notch on the cap is
positioned securely into the groove.
11•Press READ/ /TIMER for three seconds.
The display will show the countdown prior to
measurement. The beeper is playing a beep
at the end of countdown period.
Calcium only: invert again the cuvette 10
times replace the cuvette and press READ/
/TIMER .
Battery low: The battery must be replaced
soon.
Dead battery: This indicates that the battery
is dead and must be replaced. Once this
indication is displayed, normal operation of the
instrument will be interrupted. Change the
battery and restart the meter.
