Determination of the
Repeatability (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.

2. Select reproTEST
3. Start reproTEST
4. Number of measurements
is displayed; 6 measurements will
now be performed
The standard deviation
is displayed
5. End reproTEST
or restart reproTEST
Purpose
The "reproTEST" function auto-
matically determines the
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 displayed with the
balance's accuracy.
