Advantages:– Tracking form information is only entered in WinW3S

– Instrument information is entered only in WinDEM

– No double entry of hierarchical identification codes is necessary

– No empty instruments need to be entered in WinDEM

... is ensured by introducing the– CheckSum procedure

– (WinW3S Linkcheck)

Reduces mispunches, time, and costs

Linkage between WinW3S & WinDEM

12


CheckSum is created for each unique identification code (ID)

CheckSum is printed on all labels and tracking forms produced by WinW3S

WinDEM accepts unique IDs only in combination with corresponding CheckSum
