Reprotest - Sartorius FB Operating Instructions Manual

Determination of the
Reproducibility (reproTEST)
Definition
Reproducibility 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 reproducibility.
Check the Reproducibility of the Scale
Step
1. If parameter 1 9 11 is set
(reproTEST), proceed with step 4
2. Access the Selection Mode for
calibration/adjustment
3. Select reproTEST
4. Start reproTEST
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 automa-
tically calculates the reproducibility
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.
