Repeatability Test - Sartorius ME215 Operating Instructions Manual

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.
Check the Repeatability of the Balance
Step
1. If reproTEST is set:
and proceed with step 4.
If Selection mode
2. Select reproTEST
3. Start reproTEST
4. Number of the current measurement
is displayed; in this example, the 6
measurement will now be performed
The standard deviation is displayed
5. End reproTEST
or restart reproTEST
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 impor-
tant quantities in relation to the place of
installation. The results are displayed with
the balance's accuracy.
