Before you begin RI calibration, you must perform preparatory actions.
  1. Remove the refractometer from the process and place it on a table, prism pointing upwards.
  2. Clean the prism and the sample holder with ethanol cleaning solution. Make sure by looking closely that the prism is clean.
  3. Mount the sample holder on the prism.
  4. Prepare the necessary refractive index reference liquids and de-ionized water (sample liquids) and place them near the refractometer.
  5. Let the refractometer and sample liquid temperature settle to room temperature, +20 … +30 ℃ (+68 … +86 ℉). Calibration must be done within this temperature range.
    The cooling of the refractometer may take several hours.
