Hi all,

I have been searching for a while the exact meaning of the stars (asterisks) in the probe quality grades. The documented grades are  Bad, Good, No match, Perfect.

The package actually classifies my probes with the following categories:

Bad, Good, Good***, Good****, No match, Perfect, Perfect***, Perfect**** 

What is the definition of the 3 and 4 asterisks?

Are also available 1 and 2 (or more than 4) starred quality grades?

Many thanks,

Rosario
