low reagent content 

The Colormetry CMU 324 unit performs a self-diagnosis at regular intervals.

If „NEW CARTRIDGE“ is displayed during self-diagnosis, the remaining content of the reagent is low and the error message „EVALUATION ERROR“  may appear. 

→ The reagent cartridge should be replaced soon




The alarm "lack-of-reagent"  [output 3 terminals 7 + 8]  is issued when the unit has performed a certain number of analysis intervals.

Requirement for a correct timing of the "lack-of-reagent" alarm is the counter reset was correctly carried out when the cartridge was replaced.
