1st,I will go to ask the user what's up :
1 Did the instrument work normally before?
1.1 --Yes: go to 2;
1.2 --No: check instrument or call the supplier service engineer.
2 What or where has been changed?
2.1 Change back when we confirm we can keep it under control;
2.2 Try another way when it dosen't work ;
2.3 GO to 1.2 (check instrument or call the supplier service engineer) when the instrument is out of order yet.
I don't think it is very diffcult,
I think english is very diffcult :)
