E Manual calibration with mini-screw driver provided

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
