Functional description:
Light High: There is too much light to perform a
measurement. Please check the preparation of the
zero cuvet.
Light Low: There is not enough light to perform a
measurement. Please check the preparation of the
zero cuvet.
No Light:The instrument cannot adjust the light
level. Please check that the samples does not contain
any debris.
Inverted cuvets: The sample and the zero cuvet
are inverted.
Zero: A zero reading was not taken. Follow the
instructions of the measurement procedure for zero-
ing the meter.
Under range: A blinking “0” indicates that the
silica content in the sample is less than 0 mg/L.
Over Range: A flashing value of the maximum
concentration indicates an over range condition. The
concentration of the sample is beyond the

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
“deaddead
deaddead
dead” 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.
FACTORY CALIBRATION RESET
It is possible to restore the factory calibration.

Warning: do not validate or calibrate the instrument with standard
solutions other than the HANNA 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 CAL CHECK™ cuvets (see
“Accessories”) to validate or calibrate
instruments.

CALIBRATION
Note: It is possible to interrupt the
calibration procedure at any time
by pressing CAL CHECK or
ON/OFF.
1• Turn the meter on by pressing ON/OFF.
2• When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
3• Press and hold CAL CHECK for three 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 Cuvet A
into the cuvet holder and ensure that the
notch on the cap is positioned securely into
the groove.
6• Press ZERO/CFM and the instrument status
indicator will appear on the display,
depending on the measurement phase.
7• 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.
8• Remove the cuvet.
9• Place the CAL CHECK™ Standard
HI 96770-11 Cuvet B into the cuvet
holder and ensure that the notch on the
cap is positioned securely into the groove.
10• Press READ /TIMER and the instrument
status indicator will appear on the display,
depending on the measurement phase.
11• 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 HI 96770-11 Cuvets, A
and B are free from fingerprints
or dirt and that they are inserted
correctly.
Then the date of last calibration (e.g.:
“01.08.2005”) appears on the display,
or “01.01.2005” if the factory calibration
was selected before. In both cases the year
number is blinking, ready for date input.
