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

• Use matched square cuvettes, having 4 clear faces and 10

mm path length.

• Do not touch the cuvette walls with hands.

• Whenever the cuvette 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 reading.

• Samples should be completely free of air bubbles. If bubbles are present tap the cuvette on

the table to remove them.

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

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

• Do not use the same cuvette with glycerol for more than 5-10 times to perform calibration

and dispose of it after 1 day has passed.

• Never re-use honey sample cuvettes, dispose them after use.

Note: Honey samples exposed to direct sun light and/or air will darken over time. This is

caused by microorganisms.

GENERAL TIPS FOR AN ACCURATE MEASUREMENT

Over Range: A flashing value of the maximum concentration

indicates an over range condition. The concentration of the

sample is beyond the programmed range.

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.

d) other errors and warnings

Battery low: The battery must be replaced soon.

Dead battery: 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 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.
