Measuring The Baseline - wtw PhotoLab Spektral Operating Instructions Manual

10.1.3 Measuring the baseline

This function is used to newly determine the reference
absorbance or transmission for a wavelength range.
The baseline is stored and is used as a new reference
value for the spectrum measurement.
After the measurement is finished:
The measured baseline remains valid for all
the following spectrum measurements in the
same wavelength range and with the same
cell type.
Erasing the baseline
The baseline can be erased by
using the menu item, erase baseline
switching off the meter.
