After the first entry, another input field appears for the motor speed (not turntable speed). The rpm value displayed there is determined automatically. If a second value is displayed in red next to it, the speed displayed in red should also be tried, if the actual speed is not known.
A second motor speed displayed in red can also indicate a pulley or platter dimension that is only a few tenths of a millimetre off. In both cases, the calculated thickness of the belt may deviate and the entries should be checked.
The pre-tension of the belt is derived from the natural frequency of the belt in the free-hanging part, the tension surface on the pulley, the motor speed and the properties of the silicone used.
