How do I calibrate my VEE GEE MDX-Series refractometer?

Perform a zero calibration daily using distilled water. Ensure the sample well is clean, add 4-5 drops of distilled water, close the prism cover, and press and hold the ZERO key until 'CAL' is displayed. Press it again while flashing to confirm.

What is the warranty on VEE GEE digital refractometers?

VEE GEE digital refractometers come with a one-year warranty against defects in material and workmanship from the date of purchase.

How should I clean the refractometer prism?

Use distilled water or diluted isopropanol with a soft cloth or tissue. For oily residues, a mild detergent can be used. Never use abrasive materials that could scratch the optical glass.

What should I do if my MDX refractometer displays an 'A02' error?

An 'A02' error indicates a calibration sample error. Ensure you are using clean, distilled water only for zero calibration and that the sample well is free of debris.
