Precautions & Maintenance

After using, please do not use the tap water to clean directly; Otherwise the water may go into the pipe of

optical systerm.

Using method

1. Let the deviation prism point to the light, adjust the visual ring till the gage mark becomes clear.

2. Adjustment benchmark: Before using, pls keep the standard liquor (purified water), instrument and

liquid under measurement at the same temperature.Open the cover plate and apply 1~2 drops of

standard liquor onto the diviation prism, and then use hand to press the cover plate lightly to get a

dividing line. Turn the calibration screw to coincide the dividing line with the benchmark (0%). The one for

honey will be an exception.

Note: The instrument has been calibrated before delivering, you are allowed to use it directly.

3. Open the cover plate and use the soft rag to clear the surface of prism: apply 1~2 drops of liquid under

measurement onto the deviation prism and close the cover plate to press lightly; afterwards read the

relevant scale for dividing line; the reading will be the concentration value and destiny value of the liquid

under measurement.

4. After measuring, use the wet rag to clean the prism and cover plate; when it becomes dry, please store

the prism safely.
