Glossary

12 Glossary    

12.1 Terms and Formula Symbols

This chapter explains the most common terms and symbols in 

-ferrite 

content measurement and related fields (e.g., quality assurance). In 
some cases, alternate terms or synonyms are mentioned in parentheses.

-Martensit Content

Between the measured 

-ferrite content and the 

-Martensite content 

there are a correlation /28/. The following equation is used for conver-
sion the measured 

-ferrite content (Fe%) to the 

-Martensite content 

(

M%, quantity %):

²-Test  

Chi squared test (c²-Test)

AC adapter

The FERITSCOPE

®

 FMP30 can be connected to a power outlet via the 

AC adapter.

Accuracy

Qualitative designation for the degree of approximation of a measure-
ment result to the true value. Usually, the accuracy is divided into 

 Trueness (Accuracy of the mean) and 

Precision.

Accuracy

Trueness

Agreement between the “true” value 
and the mean value of a measurement 
result generally obtained under practi-
cal circumstances.

Precision

Agreement between the individual mea-
surement results under precisely defined 
test conditions.

Repeatability

Reproducibility
