Quality Assurance Tests
Even if a self check of the DOSIMAX plus A dosimeter detector combination is done after every switchon,
QA tests should be carried out at regular intervals in order to verify the general functionality, safety and general condition of the dosimeter, the detector(s) and all accessories. Please observe the environmental reference conditions stated below.
