The Single Wavelength mode can be used in three ways. For
sample readings at a single wavelength, the instrument can be
programmed to measure the absorbance, % transmittance or
concentration of the analyte.

Switches from % transmittance to concentration or absorbance in reading mode.
To input the wavelength setting. Use the alphanumeric keypad to enter the reading wavelengths.
A wavelength in the range of 190–1100 nm can be entered.
This functions as a stopwatch. It helps to make sure that the steps of an analysis are correctly
timed (e. g. reaction times, wait times, etc., can be exactly specified). When the specified time
has elapsed, a sound is emitted. The use of the timer has no influence on the reading program.

Note: If the stored program is deleted in User Programs, it will also
be deleted in Favorites Programs.
Absorbance readings: The light absorbed by the sample is
measured in absorbance units.
% Transmittance measures the percent of the original light
that passes through the sample and reaches the detector.
Turning on the concentration factor allows selection of a
specific multiplier for converting absorbance readings to
concentration. In a graph of concentration versus the
absorbance, the concentration factor is the slope of the line.
