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)

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.
