4. Maintenance

WARNING!

– When testing battery uid do not allow

the uid to come in contact with eyes or skin. Wear

appropriate PPE as specied in the relevant Safety

Data Sheet.

• This is an optical instrument, it requires careful handling

and storage. Failure to do so can result in damage to the

optical components and its basic structure. With care,

this instrument will provide years of reliable service.

• Do not expose the instrument to damp working conditions

and do not immerse the instrument in water. If the

instrument becomes foggy, water has entered the body.

Call a qualied service technician or contact your dealer.

• Clean the instrument between each measurement using a

soft, damp cloth. Failure to clean the prism on a regular

basis will lead to inaccurate results and damage to the

prism’s coating.

• Do not measure abrasive chemicals with this instrument.

They can damage the prism’s coating.

• Accurate measurement depends on careful calibration.

The prism and test uid sample must be at the same

temperature for accurate results (20°C recommended).

5. Calibration

This refractometer is a precision optical measuring device.

Before rst use it must be calibrated. This device is tted with

Automatic Temperature Compensation (ATC) and must be

initially calibrated at 20°C (68°F) ambient temperature for

both the calibration uid and the refractometer.

Open cover plate and place 2-3 drops of calibration uid

(distilled water) on the main prism (Fig.1). Close the cover

plate so the water spreads across the entire surface of the

prism without air bubbles or dry spots. Allow the sample to

temperature adjust on the prism for approximately 30

seconds before proceeding further. (This allows the sample to

adjust to the ambient temperature of the refractometer).

Hold cover plate in the direction of a light source and look into

the eyepiece. You will see a circular eld with graduations

down the centre (you may need to focus the eyepiece to clearly

see the graduations). The upper measurement eld should be

blue, while the lower up to the waterline should be white (Fig.2).

Remove the rubber cap above the calibration screw and look

into the eyepiece slowly turn the Calibration screw until the

boundary between the upper blue eld and the lower white

eld meet exactly on the waterline, shown in Fig.3. That is the

end of the calibration process.

Once calibrated, shifts in ambient temperature within the

acceptable range between 10°C-30°C should not aect

accuracy. Recalibration can be conducted as required by

the user.

6. OperationandUse

Ensuring the prism and cover plate are clean and dry, place a

few drops of the sample to be tested onto the main prism, close

the cover plate and check reading. Take the reading where the

boundary line of blue and white cross the graduated scale.

The scale will provide a direct reading of the concentration

on the relevant scale to the uid being measured. After use,

clean and dry the prism face and cover plate. Always store in

carry case when not in use and do not drop or immerse in

uid as this will irrevocably damage the refractometer.
