In my factory, we are setting the shelf life of paste on the printer to be 2hrs. What is the best way to measure this and when does the 2 hr start? It is quite difficult as sometimes the line is down for 1 hr and then start again. Should we cummulate all the down time or does it have to be a continuous 2 hrs.
I need to figure out a way to time the 2 hrs. Do give it some thought and share with me the best method.
