Follow these simple steps to calibrate your refractometer: Step 1: Prepare a calibration liquid – Start by obtaining a calibration liquid with a known refractive index. Typically, distilled water is used for this purpose. Ensure that the liquid is clean and free from impurities. If there is a discrepancy with the reading and the value you know to be true, then you will need to calibrate your refractometer. The reading error (or tolerance) taken at a set .Value. For digital refractometers, place the solution in the well and press the start button. Record the value in Table 1. The value will remain on the LED display until the next sample is read. 6. Between samples, clean the refractometer prism surface with pure water and wipe dry. 7. Repeat steps 5 & 6 with bottles marked 10-packet and 20-packet.
