4.4.1 Overview
Why calibrate? During operation, individual components of the Alyza IQ can age or become
dirty with time and thus change their characteristics, e.g.:
 Flow through cell
 LED of the photometer
 Photo diodes
 Color reagent
Regular automatic or manual calibration procedures help you to recognize any
changes of the measuring characteristics of the Alyza IQ.
2-point calibration The slope and offset of the characteristic curve are adjusted with a 2-point cali-
bration.
