PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
The HI 95759 portable microprocessor analyzer measures
the percent light transmittance of maple syrup compared to
analytical reagent grade glycerol. The transmittance value
allows identification of the syrup quality class.
Measurements are made using matched square optical
cuvets having a 10 mm light path.
Display codes aid the user in routine operations.
The meters have an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

GUIDE TO DISPLAY CODES
SIGNIFICANCE AND USE
The primary characteristic for classifying maple syrup is color.
When syrup is very light in color, as matching the minimum
light transmittance standards, the grade assigned to syrup
is high. When syrup color is dark, the grade is low. Color
classes are expressed in percent of light transmission as
compared to an analytical Glycerol Standard Reference fixed
at one hundred percent transmission. All syrup is considered
to be at minimum density, 66.0 degrees Brix at 68 °F (20
This prompt appears for 1 second
each time the instrument is turned
on.
This indicates that the meter is in a
ready state and calibration can be
performed.
Sampling in Progress. This flashing
prompt appears each time the meter
is performing a measurement.
This indicates that the meter has
been calibrated and measurement
can be performed.
Light over range: the cuvet is not
inserted correctly and an excess
ambient light is reaching the detector.
If the cap is properly installed, then
contact your dealer or the nearest
Hanna Customer Service Center.
The blinking "BAT" indicates that the
battery voltage is getting low and
the battery needs to be replaced.
This indicates that the battery is
dead and must be replaced. Once
this indication is displayed, the meter
will lock up. Change the battery and
restart.
“Configuration”: this indicates that
the meter has lost its configuration.
Contact your dealer or the nearest
Hanna Customer Service Center.
ERROR MESSAGES
a) on calibration
This indicates that the calibration
procedure failed due to a low signal-to-
noise ratio. In this case press CAL again.
“No Light”: the instrument cannot adjust
the light level. Please check that the
sample does not contain any debris.
