ERRORS AND WARNINGS
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.
On Sample Reading:
No Light:
The instrument cannot adjust the light
level. Please check that the sample does not contain
any debris.
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
“0.0”
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.
During Calibration Procedure:
Standard Low:
The standard reading is less than
expected.
Standard High:
The standard reading is higher
than expected.
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.
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.
1•
Turn the meter on by pressing
ON/OFF
.
2•
When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
The blinking
“ZERO”
indicates that the
instrument needs to be zeroed first.
3•
Fill a cuvette with 10 mL of unreacted
sample, up to the mark, and replace the
cap.
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•
Fill a beaker up to the 25 mL mark with the
sample, add the content of one packet of
HI93722-0
reagent and stir gently to mix.
9•
Fill a second cuvette with 10 mL of the
reacted sample, up to the mark, and replace
the cap.
10•
Place the second cuvette into the holder
and ensure that the notch on the cap is
positioned securely into the groove.
11•
Press and hold
READ /TIMER
for three
seconds. The display will show the count-
down prior to measurement. The beeper is
playing a beep at the end of countdown
period.
Alternatively, wait for 45 seconds and just
press
READ /TIMER.
In both cases, the lamp, cuvette and
detector icons will appear on the display,
depending on the measurement phase.
