PRELIMINARY EXAMINATION

GENERAL DESCRIPTION

The C 219 instrument measures the percent light transmittance
of maple syrup as compared to analytical reagent glycerol. The
transmittance value allows identification of syrup quality class.

Measurements are done by 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.

FUNCTIONAL DESCRIPTION

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 fixed at one hundred percent transmis­sion. All syrup is considered to be at minimum density, 66.0
degrees Brix at 68 degrees F (20

0

C), and to have no flavors

nor other characteristics extraneous to pure maple syrup.

COLOR CLASS RANGE (% Transmittance)
Extra light 75.0 to 100.0
Light 60.5 to 74.9
Medium 44.0 to 60.4
Amber 27.0 to 43.9
Dark less than 27.0

Sampling in Progress. This flashing prompt appears
each time the meter is performing a measurement.

The microprocessor is adjusting the light level, indi­cated by a scrolling “SIP”.

This indicates that the meter has been calibrated
and measurement can be performed.

Calibration was not performed. Follow the instructions
described in the measurement procedures for
calibrating the meter.

The instrument is performing an internal check-up.

The instrument cannot adjust the light level. Please
check that the sample does not contain any debris.

There is not enough light to perform a measurement.
Please check the preparation of the Glycerol cuvet.

There is too much light to perform a measurement.
Please, check the preparation of the Glycerolcuvet.

There is too much light for the sample measurement.
Please check if the right sample cuvet is inserted.

The sample and Glycerol cuvet are inverted.

The blinking "LOBAT" 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.

Light over range. The cuvet is not inserted correctly
and an eccess ambient light is reaching the detector.
If the cap is properly installed, contact your
dealer or the nearest Hanna Customer Service Center.

This indicates that the calibration procedure failed
due to a low signal-to-noise ratio. In this case press
CAL again. Or, it may indicate over range: a flash­ing 100.0% value as result of a reading
indicates that the sample absorbs less light than
the glycerol standard.

CE DECLARATION
OF CONFORMITY

• Press CAL and
“SIP” will appear
on the display.

• Wait for a few seconds and the
display will show “100.0%”. Now
the meter is calibrated and ready
for measurement.

• Remove the Glycerol cuvet.

• Add to a second cuvet 4 ml of maple syrup,
up to 5 mm (0.2") below the rim, using a
second syringe. This is the
sample.

• Place the sample cuvet into the
holder, then put the black cap on.

• Press READ and “SIP”
will appear 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 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.

%

• It is recommended to take and analyze samples at room
temperature.

• It is recommended to take the sample of maple syrup in
the middle of the container.

• 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 one use.

• Use 1 syringe for glycerol, and the other one for syrup in
order to avoid contamination.

• Samples should be completely free of air bubbles. If bub­bles are present, let the samples stand until air bubbles
have completely disappeared (not more thant 30 minutes,
see note below).

NOTE: Maple syrup samples exposed to direct sunlight and/or

air will darken over time. This is caused by microorganisms.

OPERATIONAL GUIDE

START
STOPSTOP

POWER CONNECTION
Plug the 12VDC adapter (HI 710005 - 110VDC, or HI 710006

- 220VDC) into the DC socket. Plug the adapter into the outlet.
Alternatively, remove the battery cover on the back of the

meter; attach two fresh 9 V batteries and replace the cover.
Note: insure the main line is surge protected.
Note: always turn the meter off before unplugging it to

insure no data is lost.

MEASUREMENT PROCEDURE

• Turn the meter on by pressing
ON/OFF.

• The meter will first perform an LCD
self diagnostic test by displaying a full
set of figures.

• Then it will show a scrolling
"C219 Hanna Inst"
message.

• When the LCD displays “----”,
the meter 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.

• Place the Glycerol cuvet into the
holder paying attention to the
direction of the light indicated by
the arrow, then put the black cap
on.

BATTERY REPLACEMENT

Battery replacement must only take place in a non-hazardous
area using two 9V alkaline batteries.

Remove the battery cover on the back of the meter, attach two
fresh 9V batteries and replace the cover while paying attention
to the correct polarity.

Light over range. The standard is to light for proper
calibration. If this is not the case, contact your dealer
or the nearest Hanna Customer Service Center.

This indicates that the meter has lost its configura­tion. Contact your dealer or the nearest Hanna
Customer Service Center.

To connect your meter to the PC use the optional HI 920010
cable (available from your Hanna Dealer). Make sure that your
meter is switched off and plug the connectors, one into the meter
RS 232C socket, the other into the serial port of your PC.

Note

: cables other than HI 920010 may use a different config­uration, in which case, communication between the meter and
the PC may not be possible.

Data transmission from the instrument to the PC is now much
easier with HI 92000 Windows®compatible application soft­ware offered by Hanna Instruments.

HI 92000 allows you to use the powerful capabilities of most
spread sheet programs (e.g. Excel®, Lotus 1-2-3®). Simply
open your file downloaded by HI 92000 from your spread
sheet program and then it is possible to make any elaboration
available with your software (e.g. graphics, statistic analysis).

User friendly, HI 92000 offers a variety of features and has an
on line help to support you throughout any situation.

To install HI 92000 you need a 3.5” drive and a few minutes to
follow the instructions conveniently printed on the disk label.

For acquiring data with PC from the C219 instrument select
“Real-Time Logging”. Click on “Settings” and then select the
communication port (1 to 4) and set the baud rate. The
transmission speed (baud rate) of the meter and the external
device must be identical. The meter is factory set to 2400.

If you wish to change this value, please contact your nearest
Hanna Center.

Data are recorded on PC by pressing “log sample” after
measurement has been performed. Follow the on line help for
more details.

TIPS FOR AN ACCURATE

MEASUREMENT

The instruction listed below should be carefully followed during
testing to ensure best accuracy.

• Do not touch the cuvet walls with hands.

• Whenever the cuvet is placed into the measurement cell, it
must be 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.

• Use matched square cuvets, having 4 clear faces and a
10 mm path length.

Recommendations for Users
Before using these products, make sure that they are entirely suitable for

the environment in which they are used.
Operation of these instruments in residential area could cause unacceptable

interferences to radio and TV equipments, 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 perform any measurement in micro­wave ovens.
