To calibrate it:
Put a couple drops of RO water (no salt) on the glass end with the plastic flap. Close the flap and look through the viewing end. Then use the tiny screwdriver to adjust the blue line up or down to bring it to the "0" position. The screw should be in top of the refractometer.
After that you should be good. Put a couple drops of saltwater on the glass and look at the blue line to see what the SG is at.

Hope I made sense.
