The Japan Standard calibration mode should be used only with Japanese
Polystyrene Standards (0–100 NTU).
Note: StablCal ® standards below 50 NTU should not be used to calibrate the
2020. The diluent has a different refractive index than traditional formazin
standards and will affect the results.

average of the readings that have been taken until the final average is displayed. The
