Successful verification of the WM | Quartis by the PTB

May 26th, 2020 - Successful verification of the WM | Quartis by the Physical Technical Federal Institution (PTB).

The evaluation algorithms according to Gauss and Chebyshev (minimum zone) used in WM | Quartis were successfully tested by the Physical Technical Federal Institution (PTB).
The maximum deviations are smaller than 0.10 µm and 0.10 µrad. Details on the performance of the test and the results can be found in the PTB test reports.

The correctness of the evaluation software was proved by comparing computed results with reference results provided by the PTB for the same set of data. The calculation of the parameters transmitted to the PTB was performed with WM | Quartis R2020-1.

A new test by PTB is initiated as soon as something is changed in the source code of the evaluation algorithm.
