Recall measurement
data symbol Recall saved measurement data, wavelength scans or time courses, refer to section 5.3,
page 42 .
% Trans/Abs Switches from % transmittance to concentration or absorbance in reading mode.
λ Wavelength
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.
Timer icon
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.
Concentration Factor Multiplication factor for converting absorbance values into concentration values.
Concentration
Resolution
To select the number of decimal places.
Absorbance Formula Calculation basis for evaluating samples
