rapid tests are subject to stringent checks that ensure a consistently
high quality and a high batch reproducibility. Furthermore, the Picco colorimeters are pro-
grammed by means of calibration at several points.
In the event the user chooses to adjust the instrument, this takes place at only two points
of the measuring range (zero point and measurement result). In this case it is advisable to
check the adjustment using various concentrations of a standard solution.
