For the most accurate results, the
Attenuation option should be chosen
when samples are over 500 NTU.
The range for the attenuation option
is 40–4000 NTU. C a l i b r a t i o n

Note: StablCal â standards below 50 NTU should not be used to calibrate the
TC-3000. The diluent has a different refractive index than traditional formazin
standards and will affect the results. The Japan Standard calibration mode should
be used only with Japanese Polystyrene Standards (0–100 NTU).
