3.2.3.3 RP1 Method for Repeatability Test
The RP1 Method calculates the mean value and standard deviation (symbol s) of a measurement series using a single test weight to
determine the repeatability of the balance.
Method Sequence:
1. Zero
2. Load Test Weight
3. Unload Test Weight
4. Repeat steps 2 and 3
5. Unload all weights
6. Zero
“Test Weight”: A pre-defined test weight and its corresponding test tolerances can be selected here (see section
3.2.3.1).
Note: The test tolerances of the test weight are valid for every individual weight value, but do not apply
to the standard deviation that is to be calculated.
Note: If you require the repeatability test to be fully executed the test weight tolerances should be set
to 100 %.
“Tolerances s”: The RP1 Method uses two result tolerances (method tolerances) s T1 and s T2 which are applied to the
calculated standard deviation of the Test Sequence and functions in the same way as described for T1
and T2 in section 3.2.3.1. If Tolerance s T1 is exceeded, the Repeatability Test will pass with warning.
If Tolerance s T2 is exceeded, the Repeatability Test will fail.
“Number of Repetitions”: Define the number of weight measurements in the series.
Valid range of input: 2 - 15
Factory Setting: 10
