IMPORTANT PRECAUTIONS
▪ DO NOT place fuel on the measuring surface.
▪ DO NOT SUBMERGE INSTRUMENT IN LIQUIDS.
▪ DO NOT STORE INSTRUMENT WITHOUT MAKING
SURE IT IS CLEAN AND DRY.
▪ DO NOT hold instrument under running water.
▪ DO NOT leave instrument in direct sunlight or in a
vehicle on a sunny day.
▪ DO NOT subject instrument to temperatures above
50°C (122°F) or below -10°C (14°F).
▪ DO NOT attempt to repair, modify, or disassemble any
portion of the instrument.
▪ DO NOT let liquid fall from instrument onto clothing or
other surfaces after taking readings.
▪ DO NOT drop or subject instrument to strong shocks or
vibrations.
▪ DO NOT use a metal device to transfer samples to the
measuring surface.
▪ DO NOT use an instrument unless you have personal
knowledge of its calibration.
▪ DO NOT attempt to recharge the batteries that came
with the instrument.
▪ DO NOT press the buttons with anything other than a
finger.
▪ DO NOT clean instrument with cleaners or solvents.
CALIBRATION
The refractometer MUST be calibrated before initial use and
periodically thereafter. Calibration is recommended at least
once a day as well as prior to performing tests requiring the
highest precision, or when moving between environments
with extreme changes in ambient temperature.
A clean container of water is all that is needed to
automatically calibrate the instrument. Although tap water
may be used, distilled or deionized water is recommended.
The water temperature should ideally be between 10°C to
30°C (50° to 86°F). It is important to independently verify that
you are indeed calibrating the instrument with water and not
just a clear liquid which you think is water.
Never use an instrument unless you have personal
knowledge of its calibration.
CALIBRATION PROCEDURE
1. Inspect the measuring surface to make sure it is clean
and dry. Place about 0.5 mL of distilled water on
measuring surface.
2. Close the sample cover and allow some time for the
temperature to equalize. The sample cover MUST be
closed to calibrate or take readings.
3. Press and release <GO> to turn the instrument on.
4. Press and release <MENU> until the display reads
“SET ZERO? (GO) TO SET.”
5. Press and release <GO> to automatically calibrate the
instrument. Remember to clean and dry the measuring
surface after calibration.
OBTAINING A TEST SAMPLE
Obtain a test sample by following the ASTM D5006
procedure. Distilled or deionized water is recommended.
TAKING READINGS
1. A single press and release of <GO> will turn the
instrument on.
2. Inspect the measuring surface to make sure it is clean
and dry. Use a clean, disposable, plastic pipette or
syringe (without a needle) to place about 0.5mL of the
sample to be tested on the measuring surface. This
sample must not have any fuel in it.
3. Always close the sample cover and allow some time for
the temperature to equalize. A good rule of thumb is to
wait at least 30 seconds for every 20°F (10°C)
difference in temperature between the fluid and the
instrument.
4. Press <GO> to automatically trigger a reading. The
display will indicate the scale on the first line of the
display and * READING * on the second line.
5. The reading will take about five seconds and the result
will be displayed on the screen.
6. Press and release <GO> to take a second reading.
7. Use the same pipette used for application to suck away
the sample and dispose of it properly. Wipe away any
remaining residue with a damp cloth and then wipe dry.
Make sure the surface is clean and dry before next use.

MENU OPTIONS
The Zero Set option will zero or calibrate the
instrument to water.
This function is not yet available.
This option allows you to turn the LCD
display backlight on or off. The options are
“Yes” and “No.”
Follow the prompts to select the display
language from the five options and press
<GO> to set.
AUTO TEMPERATURE COMPENSATION
The speed of light in a liquid increases as temperature
increases, and the refractive index, therefore, decreases.
Automatic temperature compensation ensures that
concentration readings of aqueous (water-based) solutions
will be accurate with respect to the sample’s temperature.
Samples should be read at an ambient temperature as close
to 20°C (68°F) as possible for the best precision. Scales are
programmed with temperature compensation specific to an
individual unit of measure. This will be noted on the
specification card accompanying the instrument.
For the most accurate possible results, the instrument, the
ambient temperature, and the fluid should be in equilibrium
with the instrument’s temperature range.
CARE AND MAINTENANCE
Keep the measuring surface clean! It is extremely important
to thoroughly clean the measuring surface after each use
with a wet, soft, clean cloth or paper towel. This will prevent
cross-contamination between samples and provide accurate
subsequent readings. Keep the measuring surface clean
and free of residue at all times. The instrument body may be
cleaned with a soft, clean cloth or paper towel, dampened
with a mild liquid dish soap and water. The use of solvents or
petroleum-based cleaners is not recommended.
TROUBLESHOOTING
The most common source of error is trying to take readings
with the cover open. If this is not the case, and you suspect
the instrument is malfunctioning or giving an erroneous
reading, try calibrating it and take a reading of water to check
the zero set. If the instrument readings are still suspicious,
replace the battery and repeat the above procedure.
If the instrument “locks up” and will not read or shut off, clear
the instrument by removing the batteries. If the unit fails to
display “GAMMON/PALM ABBE II” when starting, check the
battery insertion and polarity. If the unit still will not start,
check the battery charge and/or replace the batteries. If
batteries are good and instrument still will not start, call GTP
for support.
