The instructions listed below should be carefully followed
during testing to ensure best accuracy.
• Use matched square cuvets, having 4 clear faces and a
10 mm path length.
• Do not touch the cuvet walls with hands.
• Whenever the cuvet is placed into the measurement cell,
it must be dry outside, and completely free of fingerprints,
oil or dirt. Wipe it thoroughly with
HI 731318
or a lint-
free cloth prior to insertion.
• It is important that the sample does not contain any
debris. This would corrupt the readings.
• Samples should be completely free of air bubbles. If
bubbles are present, let the samples stand until air
bubbles have completely disappeared (not more than
30 minutes, see note below).
• It is recommended to take the sample of maple syrup in
the middle of the container.
• It is recommended to take and analyze samples at room
temperature.
GENERAL TIPS FOR AN
ACCURATE MEASUREMENT
Recommendations for Users
Before using these products, make sure that they are entirely suitable for your specific
application and for the environment in which they are used.
Operation of these instruments may cause unacceptable interferences to other electronic
equipments, this requiring the operator to take all necessary steps to correct interferences.
Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.
To avoid damages or burns, do not put the instrument in microwave oven. For yours and
the instrument safety do not use or store the instrument in hazardous environments.

BATTERY REPLACEMENT
Battery replacement must only take place in a non-hazardous
area. 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. Replace the battery and replace the cover.

“Light Low”: there is not enough light
to perform a measurement. Please check
the preparation of the Glycerol cuvet.
“Light High”: there is too much light to
perform a measurement. Please check
the preparation of the Glycerol cuvet.
b) on sample reading
There is too much light for the sample
measurement. Please check if the right
sample cuvet is inserted.
“Cal”: calibration was not performed.
Follow the instruction in the
operational guide
for calibrating
the meter.
A blinking “100.0” on sample reading
is a warning that the Glycerol Reference
cuvet is still inserted in the instrument,
or indicates that the sample absorbs less
light than the Glycerol Reference. Check
the procedure and recalibrate the
instrument.
IST95759R1 09/02
• Do not use the same cuvet with glycerol for more than
5-10 times to perform calibration and dispose of it after
1 day has passed.
• Never re-use maple syrup sample cuvets, dispose of
them after use.
• Use one syringe for glycerol, and the other one for syrup
in order to avoid contamination.
Note:
Maple Syrup samples exposed to direct sunlight
and/or air will darken over time. This is caused by
microorganisms.
• Turn the meter on by pressing ON/OFF.
When the LCD displays “759”, it is ready.
• To perform calibration, use a
first syringe to fill one cuvet
with 4 mL of Glycerol, up to 5
mm (0.2”) below the rim. This
is the Glycerol Standard
Reference.
• Place the Glycerol cuvet into
the holder paying attention to
the direction of the light
indicated by the arrows on the
instrument. Then put the light
shield cap on and ensure that
the notch on the cap is
positioned securely into the
groove.
• Press CAL and “SIP” will blink on the display.
• After a few seconds the display
will show “100.0”. The meter is
now calibrated and ready for
measurement.
OPERATIONAL GUIDE
• Remove the Glycerol cuvet.
• Use the second syringe to add
to a clean cuvet 4 mL of maple
syrup, up to 5 mm (0.2”)
below the rim. This is the
sample.
• Place the sample cuvet into
the holder paying attention to
the direction of the light
indicated by the arrows on the
instrument. Then put the light
shield cap on and ensure that
the notch on the cap is
positioned securely into the
groove.
• Press READ and “SIP” will blink during measurement.
• The instrument directly displays percent of light
transmittance as compared to Glycerol Standard (fixed
at one hundred percent).
• Check in the manual or on the front panel to which
color class the transmittance value corresponds.
INTERFERENCES
Interference may be caused by air bubbles or turbidity in
the sample. Scratched or dirty cuvets will also affect readings.
Always check clearness of cuvets prior to use.
