Hi Pascal
you haven't provided much information. But as a starter:
Assumptions: column A stores your measurment data
- enter the following in B2
=IF(ABS(A2-AVERAGE($A$1:$A1))epsilon,"massive change","")
and copy down (replace epsilon with a value of your choice)

or you may use
=IF(ABS(A2-A1)epsilon,"massive change","")
