Hanna Instruments HI 95747 - Manual (Page 2)

Validation
In both cases “SIP” will blink during
measurement.
11•The instrument directly displays concentration
in mg/L of copper on the Liquid Crystal
Display.
INTERFERENCES
• Cyanide
• Silver
• For strongly buffered alkaline or acidic samples,
pH should be adjusted between 6 and 8 before
addition of reagent.
• To avoid interferences due to fingerprints, oil or
dirt it is very important that the cuvet is wiped
clean prior to insertion in the cuvet holder.
Replacement of scratched cuvets is strongly
recommended.
Calibration
Battery replacement
Battery replacement must only take place in a non-hazardous environment.
Simply slide off the battery cover on the back of the meter.
Detach the battery from the terminals and attach a fresh 9V battery
while paying attention to the correct polarity. Insert the battery and
replace the cover.

It is possible to restore factory calibration:
Factory calibration reset
Factory
Calibration
Reset
1• Enter the calibration mode by holding CAL
CHECK key for three seconds.
2• Hold ZERO for 10 seconds. The display will
show for 2 seconds “F.CAL” and the parameter
code “747” appears. The factory calibration
is automatically restored and the instrument
is ready for measurement.
Validation and Calibration procedures
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 optional CAL CHECK™ cuvets (see
“Accessories”) to validate or calibrate
instruments.
VALIDATION
1• Turn the meter on by pressing ON/OFF.
2• When the LCD displays “747”, it is ready.
3• Place the CAL CHECK™ Standard Cuvet A
into the holder and ensure that the notch on
the cap is positioned securely into the groove.
4• Press ZERO and “SIP” will blink on the
display.
5• After a few seconds the display will show
“-0.0-”. The meter is now zeroed and ready
for validation.
6• Remove the cuvet.
7• Place the CAL CHECK™ Standard
HI 95747-11 Cuvet B into the holder and
ensure that the notch on the cap is positioned
securely into the groove.
8• Press CAL CHECK key and “SIP” will blink
during measurement.
9• Wait for a few seconds and 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 cuvets are
free of fingerprints, oil or dirt and repeat
validation. If results are still found out of
specifications then recalibrate the instrument.
CALIBRATION
Note: It is possible to interrupt the calibration
procedure at any time by pressing ON/OFF.
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).
1• Turn the meter on by pressing ON/OFF.
2• When the LCD displays “747”, it is ready.
3• Enter the calibration mode by holding CAL
CHECK key for three seconds.
4• The date of the last calibration appears (e.g.:
month “01”, day “08”). “F.CAL” means that
the factory calibration is selected.
Note: at this point it is possible to reset the
instrument to restore FACTORY CALIBRATION
5• Place the CAL CHECK™ Standard Cuvet A
into the holder and ensure that the notch on
the cap is positioned securely into the groove.
6• Press ZERO and “SIP” will blink on the
display.
7• After a few seconds the display will show
“-0.0-”. The meter is now zeroed and ready
for calibration.
8• Remove the cuvet.
9• Place the CAL CHECK™ Standard
HI 95747-11 Cuvet B into the holder and
ensure that the notch on the cap is positioned
securely into the groove.
10•Press READ/TIMER and “SIP” will blink on the
display.
11•The instrument will show for three seconds the
CAL CHECK™ standard value.
Then the date of last calibration (e.g.:
“01.08”) appears on the display, or “01.01”
if the factory calibration was selected. In both
cases the number of the month is blinking,
ready for date input.
Note: if display will show “ERR” the calibration
procedure failed. Verify that the right CAL
CHECK™ Standard Cuvet B is inserted, that
both A and B cuvets are free from fingerprints
or dirt and that they are inserted correctly.
12•Keep READ/TIMER pressed to scroll to the
desired month number (01-12).
13•When the correct month has been set, press
ZERO to confirm. Now the display will show
the day number blinking.
Keep READ/TIMER pressed to scroll to the
desired day number (01-31).
Note: it is possible to change from day to month
and vice versa by pressing ZERO.
14•When both the day and month have been
selected, hold CAL CHECK key for three seconds
to store date and calibration values. The
instrument will show for one second “Stor”, to
confirm that the new calibration data has
been accepted.
15•The instrument will return automatically to
the measurement mode by displaying the
parameter code (“747”) on the LCD.
