Step 1
Enter the first wavelength by using the keypad
numbers or the left and right arrows.
Press the down arrow key.
Step 2
Enter the second wavelength as above.
Press the down arrow key.
Step 3
Select whether or not to adjust the name of your
sample before each new run, using left and arrow
keys to select Yes or No.
Pres the down arrow key.
Step 4
Select whether a background correction is on or off.
Step 5 (If background correction is On)
Enter the third wavelength, from which the
background correction will be obtained.
Step 6

Step 7 (Dilution Factor known)
Enter a dilution factor by using the keypad numbers
within the range 1.00 – 9999 or calculate a dilution
factor.
Absorbance Ratio
This makes simple absorbance ratio measurements on samples, measuring the amount of light that has passed through a
sample relative to a blank (this can be air) at two wavelengths.
The procedure is as follows:
