I bought a refractometer from Dr. Fosters and I also bought the Pinpoint 53.0 µS Calibration/Reference Fluid. The directions that came with the refractomeeter said that you can use either distilled water or calibration fluid. I decided to use distilled water because I was not sure how to calibrate it using the calibration fluid. I read in a few places that it is better to use the calibration fluid rather than distilled water.

The calibration fluid did not come with any directions, so what level should I be looking for when calibrating with it? Thanks.
