  • Page 30: Color Correction Factor (Ccf)

    When measuring under a light source which has a considerably different spectral distribution from T-10A/T-10MA’s calibration light source, the instrument will cause an indication error due to a slight deviation of the relative spectral response from spectral luminous efficiency (Vλ). To correct this error, this instrument has CCF function (mode), allowing you to set the color correction factor (CCF).
