Sie können die Besaitungshärte nach dem Besaiten ihres Schlägers messen. Diesen gemessenen Wert vergleichen Sie mit dem Messwert in einer Woche. Wenn sich dieser Wert zu stark ändert, und größer als drei bis fünf kg ist, besaiten Sie ihren Schläger neu. So ist immer gewährleistet, daß Sie die richtige Bespannhärte auf ihrem Schläger haben. Der Minni STT arbeitet über Schwingungen. Das Racket wird in Schwingungen versetzt. Diese Schwingungsänderungen, bei verschiedenen Bespannungshärten, werden gemessen. Die Racketkopfgröße muß vorher eingestellt werden. Die deutsche Bedienungsanleitung ist leicht zu verstehen. Der Mini STT gehört in jeder Tennistasche.
