VALIDATION AND CALIBRATION PROCEDURES
Warning: do not validate or calibrate the instrument with standard solutions other than the Hanna Instruments CAL Check™ Standards, otherwise
erroneous results will be obtained.
For accurate validation and calibration results, please perform tests at room
temperature (18 to 25 °C; 64.5 to 77.0 °F).
Use the Hanna Instruments CAL Check™ cuvettes (see
“Accessories”) to validate or calibrate instruments.
Validation
1• Turn the meter on by pressing ON/OFF.
2• When the beeper sounds briefly and the
3
LCD displays dashes, the meter is ready.
3• Place the CAL Check™ Standard
HI96738-11 Cuvette A into the holder
and ensure that the notch on the cap is 4-5
positioned securely into the groove.
4• Press ZERO/CFM and the lamp, cuvette and
detector icons will appear on the display,
depending on the measurement phase.
5• After a few seconds the display will show
“-0.0-”. The meter is now zeroed and ready
for validation.
6• Remove the cuvette.
7• Place the CAL Check™ Standard 7
HI96738-11 Cuvette B into the holder
and ensure that the notch on the cap is
positioned securely into the groove.
8• Press CAL CHECK key and the lamp,
cuvette and detector icons together with
“CAL CHECK” will appear on the display,
depending on the measurement phase.
9• At the end of the measurement the display
will show the validation standard value.
The reading should be within specifications as reported on the CAL Check™
Standard Certificate. If the value is found
out of specifications, please check that the
cuvettes are free of fingerprints, oil or dirt
and repeat validation. If results are still
found out of specifications then recalibrate
the instrument.

2• When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
3''
3• Press and hold CAL CHECK for three 3
seconds to enter calibration mode. The
display will show “CAL” during calibration
procedure. The blinking “ZERO” asks for
instrument zeroing.
4• Place the CAL Check™ Standard
HI96738-11 Cuvette A into the cuvette 4
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, 5-6
depending on the measurement phase.
6• After a few seconds the display will show
“-0.0-”. The meter is now zeroed and ready
for calibration. The blinking “READ” asks
for reading calibration standard.
7• Remove the cuvette.
8• Place the CAL Check™ Standard
HI96738-11 Cuvette B into the holder
and ensure that the notch on the cap is 8
positioned securely into the groove.
9• Press READ and the lamp, cuvette and
detector icons will appear on the display,
depending on the measurement phase.
9-10
10• The instrument will show for three seconds
the CAL Check™ standard value.
Note: If the display shows “STD HIGH”, the
standard value was too high. If the display
shows “STD LOW”, the standard value
was too low. Verify that both CAL Check™
Standard HI96738-11 Cuvettes, A and B
are free of fingerprints or dirt and that they
are inserted correctly.

11• Then the date of last calibration (e.g.: 11-13
“01.08.2009”) appears on the display,
or “01.01.2009” if the factory calibration
was selected before. In both cases the year
number is blinking, ready for date input.
12• Press GLP/ to edit the desired year
(2009-2099). If the key is kept pressed,
the year number is automatically increased.
13• When the correct year has been set, press
ZERO/CFM or READ to confirm. Now
the display will show the month blinking.

To save the battery, the instrument shuts down after 10 minutes of non-use
in measurement mode and after 1 hour of non-use in calibration mode.
If a valid measurement was displayed before
auto-shut off, the value is displayed when the
instrument is switched on. The blinking “ZERO”
means that a new zero has to be performed.
One fresh battery lasts for around 750 measurements, depending on the
light level.
The remaining battery capacity is evaluated at the instrument startup and
after each measurement.
The instrument displays a battery indicator with three levels as follows:
• 3 lines for 100 % capacity
• 2 lines for 66 % capacity
• 1 line for 33 % capacity
• Battery icon blinking if the capacity is under 10 %.
If the battery is empty and accurate measurements can’t be taken any
more, the instrument shows “dEAd bAtt” and turns off.
To restart the instrument, the battery must be replaced with a fresh one.
To replace the instrument’s battery, follow the steps:
• Turn the instrument off by pressing ON/OFF.
• Turn the instrument upside down and remove the battery cover by
turning it counterclockwise.
• Extract the battery from its location and replace it with a fresh one.
• Insert back the battery cover and turn it clockwise to close.
RECOMMENDATIONS FOR USERS
Factory Calibration Restore
It is possible to delete the calibration and
restore factory calibration.
1• Press GLP/ to enter GLP mode.
2• Press READ to enter in the factory calibration restore screen. The instrument asks
for confirmation of user calibration delete.

ERRORS AND WARNINGS
On zero reading:
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.
6• Add precisely 0.5 mL of HI93738C-0
Reagent C to each cylinder (#1 & #2),

It is recommended to analyze chlorine dioxide
samples immediately upon collection. Chlorine
dioxide samples must be stored in dark, glass
stoppered bottles, with minimal head space.
Excessive heat (greater than 25 °C / 78 °F),
agitation and exeposure to light must be
avoided.
Other errors and warnings:
Cap error: Appears when external light enters
in the analysis cell. Assure that the cuvette cap
is present.
Interference may be caused by strong oxidants.
5• Add the content of one packet of
HI93738B-0 Reagent B to only one of
the two cylinders (#1), close it and invert

PRELIMINARY EXAMINATION
12
No Light: The instrument cannot adjust the
light level. Please check that the sample does
not contain any debris.
On sample reading:
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 “0.00” 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.
