List of available absorbance formulas
A1 is the absorbance at wavelength 1,
A2 is the absorbance at wavelength 2 and so on K1 is the factor at wavelength 1,
K2 is the factor at wavelength 2 and so on
If a subtraction has to be completed, the factors can be entered with a minus sign.
Wavelength λx:
Press a λx key and use the alphanumeric keypad to enter a wavelength. Press another λx key and enter the next wavelength. If necessary, repeat until all the wavelengths for the formula have been entered. The wavelengths must be in the range from
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 5 digits can be entered, including a maximum of 4 decimal places to the right of the decimal.
Concentration resolution (number of decimal places)
Select the required number of decimal places from the displayed list and press Next.
