Calibration:
1. Calibration should be made in an ambient environment of 20degree Celsius.
2. Open the Light Plate & place a tiny drop of calibration fluid in the center of the
prism.

RBX4582 78.8% Sucrose Solution 78.8%
RBX5890 78.8% Sucrose Solution 78.8%
3. Use the provided Glass Block and place the frosted side of block on the
center of prism where the fluid is. Ensure the water is spread across the entire
surface of the Glass Block. There must not be any bubbles or dry spots on
the glass block, which is cause by too little liquid use.
4. Wait for about 30 seconds, this is to allow the temperature compensation to
take place.
5. Hold the meter in the direction of light source and look into the Eyepiece.
6. Adjust the Focus Dial until image is clear and sharp. Each person has his
own focusing adjustment.
7. Remove the rubber cap on the Calibration knob, with the use of the provided
trimming tool and adjust it until the bottom line of the darkest blue section is at
the brix scale reads precisely the Calibration Point above. Disregard faint or
white lines
8. Calibration Completed.
9. Rinse the Glass Block and Prism with water and wipe them with soft lint-free
clothes before proceeding with measurement.

Making Measurement:
1. Open the light plate & place 2 to 3 drops of the test liquid on the prism.
2. Close the Light Plate. Ensure the water is spread across the entire surface of
the Prism. There must not be any bubbles or dry spots.
3. Wait for about 30 seconds, this is to allow the temperature compensation to
take place.
4. Hold the meter in the direction of light source and look into the Eyepiece.
5. Select the scale, which is the intended unit of measurement.
6. Take the reading from the scale on the line where the darkest blue and white
area meets. Disregard faint or white lines
7. Wipe dry the Light Plate and Prism with a soft lint-free clothe after each and
every test and before storing away.
8. It is important to maintain the Light Plate and Prism dust and stain free in order
to have good repeatability measurement.
Precautions in Usage:
1. Clean the instrument between each measurement and before storage with a
soft cloth. Residue of samples stained on the prism could damage the coating
on the prism.
2. Do not measure with abrasive or corrosive chemicals. This will damage the
prism’s coating.
3. Do not immerse the instrument in water. If the view inside the Eyepiece
becomes foggy, water has entered into the body. Call a qualified service
technician or contact your dealer.
4. Do not clean the prism with thinner as this will remove the special coating on
the prism and damage the unit.
5. Do not store the instrument in a damp environment. Store only in a cool and
dry environment.
6. This is an optical instrument and requires careful handling and storage. With
care, this instrument will provide years of reliable service.
