7 Calculation of trum length, belt weight and trum force
7.1 Trum length
As a rule, the trum length can be measured directly on the belt. Measure the length described above
(trum length) and enter it in the "Force" menu as the length. Sometimes it is not possible to measure
this length - then you can determine the length using the following formula:
