Calibration:

1. Calibration should be made in an ambient environment of 20degree Celsius.
2. Open the Light Plate & place few drops of distilled water ½ fill the prism.
3. 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 on the Prism, 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 blue section is at 1.000sg
or 0%.
8. Calibration Completed.
9. Wipe dries the Light Plate and Prism with soft lint-free clothes before
proceeding with measurement.
