Wavelength λ
:
x
Press a λ
key and use the alphanumeric keypad to enter a
x
wavelength. Press another λ
necessary, repeat until all the wavelengths for the formula have
been entered. The wavelengths must be in the range from
190–1100 nm. Press OK.
Concentration Factor Kx
Multiplication factor for converting absorbance values into
concentration values.
Press a factor key and use the alphanumeric keypad to enter a
factor. If the formula includes more than one factor, press another
factor key and enter another factor and repeat until all the factors
have been entered. Press OK. When all the relevant data have
been entered, press Next.
Note: Up to five digits can be entered, including a maximum of 4 decimal
places to the right of the decimal.
