6-2. Periodic Check
Periodic check is necessary to verify performance of refractometer. When unexpected
physical force is given to the unit, precision of measurement must also be checked to see
if different results should appear.
Check by user
1) Check or calibrate the unit according to the instruction in manual.
2) Measure Refractive index standard liquid or Brix converted RI standard liquid. For
check reference solution, it is recommended to use a standard liquid of which refractive
index is close to the value that you frequently obtain in measurement.
(RI standard liquid and Brix converted RI standard liquid are available from KEM.
See [6-4. Consumables and parts])
3) If repeated measurements result with an error deviated from range in [8-3.
Specifications], consult with your local dealer or sales representative.
