Description
Measurements at a defined wavelength
In the Multi Wavelength mode, absorbance values can be measured at up to four wavelengths
and the results can be mathematically processed to obtain sums, differences and relationships.
This is an advanced form of programming for original user-developed methods. In Free
Programming, the user defines the measurement process, variables and calculations involved in
obtaining a reading.
