FUNCTIONAL DESCRIPTION
DISPLAY ELEMENTS DESCRIPTION:
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.
On sample reading:
During calibration procedure:
Other errors and warnings:
Cooling lamp:
The instrument waits for the
lamp to cool down.
Standard High:
The standard reading is higher
than expected.
On zero reading:
ERRORS AND WARNINGS
Battery low:
The battery must be replaced soon.
3•
Calcium:
Using a 5 mL syringe add exactly
3 mL of sample to the cuvette. Use the pi-
pette to fill the cuvette up to the 10 mL mark
with the
HI93752A-Ca
Buffer Reagent. Add
4 drops of Buffer Reagent.
Magnesium
: Using a 1 mL syringe add
exactly 1 mL of
HI93752A-Mg
Buffer Re-
agent. Use the pipette to fill the cuvette up
to the 10 mL mark with the
HI93752B-Mg
Indicator Reagent.
4•
Replace the cap and invert several times
to mix. 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
HI93752B-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 en-
sure 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 cuvette 10
times again before the timer expires.
Alternatively, wait for 5 minutes then
invert the cuvette 10 times and press
READ /TIMER.
Magnesium only: Alternatively, wait for
15 seconds and press
READ /TIMER
. In
all cases the lamp, cuvette and detector icons
will appear on the display, depending on the
measurement phase.
12•
The instrument directly displays concentration
in mg/L of Calcium or Magnesium on the
LCD, depending on the selected parameter.

No Light:
The instrument cannot adjust the
light level. Please check that the sample does
not contain any debris.
Light Low:
There is not enough light to perform
a measurement. Please check the preparation of
the zero cuvette.
Light High:
There is too much light to perform
a measurement. Please check the preparation of
the zero cuvette.
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.
Standard Low:
The standard reading is less
than expected.
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.
Cap error:
Appears when external light enters
in the analysis cell. Assure that the cuvette cap
is present.
