Determination of the Repeatability (
reproTEST
)
Definition
Repeatability is the ability of the scale 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 of results
(based on 6 individual measurements).
In this way, the scale determines one of
the most important quantities in relation
to the place of installation. The results are
displayed with the scale’s accuracy.
