MEASUREMENT PROCEDURE
9
Measurement
1
1• Turn the meter on by pressing ON/OFF.
2
2• When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
The blinking “CAL” indicates that the
instrument needs to be calibrated first.
3• Fill one cuvette with 4 mL of Glycerol,
up to 5 mm (0.2”) below the rim. This
is the Glycerol Standard Reference.

5
4• Place the cuvette into the holder paying
attention to the direction of the light
indicated by the arrow on the instrument. Then put the light shield cap on
and ensure that the notch on the cap
is positioned securely into the groove.
5• Press CAL and the lamp, cuvette and
detector icons will appear on the display, depending on the measurement
phase.

9• Place the sample cuvette into the holder
paying attention to the direction of the
light indicated by the arrow on the
instrument. Then put the light shield
cap on and ensure that the notch on
the cap is positioned securely into the
groove.
10• Press READ and the lamp, cuvette and
detector icons will appear on the display,
depending on the measurement phase.
11• At the end of measurement, the
instrument directly displays the honey
color intensity value expressed in mm
Pfund, as compared to analytical grade
Glycerol (fixed at zero mm Pfund).
INTERFERENCES
Interference may be caused by air bubbles or turbidity in the sample.
Scratched or dirty cuvettes will also affect readings. Always check
clearness of cuvettes prior to use.
ERRORS AND WARNINGS
On Calibration Reading
6
6• After a few seconds the display will
show “-0.0-”. The meter is now calibrated and ready for measurement.
7• Remove the cuvette.
8
8• Add to a second clean cuvette about
4 mL of honey, up to 5 mm (0.2”)
below the rim. This is the sample.
Light High: There is too much light to
perform a measurement. Please check the
preparation of the calibration cuvette.
Light Low: There is not enough light to
perform a measurement. Please check the
preparation of the calibration cuvette.
BATTERY MANAGEMENT
On Sample Reading:
Inverted cuvettes: The sample and the
calibration cuvette are inverted.
CAL: A calibration reading was not taken.
Follow the instructions of the measurement
procedure for calibrating the meter.
Under range: A blinking “0” indicates
that the sample absorbs less light than the
calibration reference. Check the procedure
and recalibrate the instrument.
Over Range: A flashing value of the
maximum concentration indicates an over
range condition (on both wavelenghts). The
concentration of the sample is beyond the
programmed range.
A flashing value lower than the maximum
concentration (e.g. “120”) indicates an
over range condition on one wavelenght.
The displayed concentration value (e.g.
“120”) is the reading obtained on the other
wavelenght.
Other Errors and Warnings:
Cap error: Appears when external light
enters in the analysis cell. Assure that the
light shield cap is present.
Cooling lamp: The instrument waits for the
lamp to cool down.
Battery low: The battery must be replaced
soon.
No Light: The instrument cannot adjust the
light level. Please check that the calibration
cuvette does not contain any debris.
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.
Dead battery: This indicates that the battery
is dead and must be replaced. Once this
indication is displayed, normal operation of
the instrument will be interrupted. Change
the battery and restart the meter.
• Extract the battery from its location and replace it with a fresh one.
• Insert back the battery cover and turn it clockwise to close.

SIGNIFICANCE AND USE
Honey color varies naturally in a wide range of tonalities, ranging
from light yellow to amber, dark amber and black in extreme cases;
sometimes green or red hues may also occur.
Color of untreated honey depends on botanical origin: for this reason
color is very important for definition and commercial classification of
monofloral honeys. Honey darkens with ageing, and other changes in
color may result from beekeeper’s interventions and from the different
ways of conservation (e.g.: use of old honeycombs, contact with metals,
high temperatures, exposition to light, etc.).
The primary characteristic for commercial honey classification is
color. Color classes are expressed in millimeters (mm) Pfund grades,
compared to an analytical grade Glycerol Standard Reference.
Table 1 reports the USDA classification for honey samples and the
related mm Pfund values.
Table 2 shows the color of different monofloral honeys: data are
obtained from a statistical set of honey samples. The table reports for
each type of honey: average value of color, standard deviation, and
the minimum and maximum values measured.

Analysis Kit
AVERAGE
(mm Pfund)
The HI96785 portable microprocessor analyzer measures the percent
light transmittance of honey compared to analytical reagent grade
glycerol. The transmittance value allows identification of the honey
Pfund grade. The instrument directly displays the measurement
result expressed in mm Pfund.
Measurements are made using matched square optical cuvettes
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.
