3.1 Colour correction
Light-absorbent colorants in the sample can distort the results of the luminescent
bacteria test. The LUMIStox 300 has an automatic colour and turbidity compensation
feature. This means that the absorbed light can be automatically determined and
corrected with the built-in photometer function each time a measurement procedure is
carried out. The measurement takes a few seconds longer than usual. The colour
correction can be performed in the extinction range from 20 - 1800 mE.
Sequence:
The colour correction feature can be switched off, permanently switched on, or
switched on as required. In the latter case, each time a measurement program is
selected the user is asked whether the colour correction feature should be switched on.
