Ratio =
(b) NUM WL ‘3’ (Data Mode: Conc)
The photometric values A (WL1), A (WL2) and A (WL3) at three specified
wavelengths are calculated base on the following formula.
D = (WL2 – WL3) – (WL1 – WL3)
A(WL3) - A(WL1)
A(WL3) - A(WL2)
Ratio =
(c) When NUM WL Ranges from 2 to 6 (Data Mode: ABS or T%)
When data mode is ABS (or T%), absorbance (or transmittance) at each set
wavelength is displayed.
