Repeatability Test (reproTEST)
Definition
Repeatability is the ability of the balance
to display identical readouts when it is
loaded several times with the same weight
under constant ambient conditions. The
standard deviation for a given number of
measurements is used to quantify the
repeatability.

Purpose
The "reproTEST" function automatically
determines the repeatability (also called
"reproducibility") of results (based on
6 individual measurements). In this way,
the balance determines one of the most
important quantities in relation to the
place of installation. The results are dis-
played with the balance's accuracy.
